Description

1 / 15 Portable automatic pellet burner with remote electronic monitoring. TECHNICAL FIELD OF THE INVENTION

[001] The present invention falls within the field of heat energy generation equipment, comprising furnaces, ovens and dryers, where a diverse variety of fuel sources are used, such as gas, electricity, biomass and fossil fuels. Hundreds of professional and business activities require thermal energy daily to carry out their work. Bakeries, pizzerias, hotels, clubs, laundries, swimming academies, motels, poultry farms, candy factories, ceramics factories, greenhouses, among others, need equipment capable of generating heat to capture this thermal energy in their activities, and this generation of thermal energy is one of their main costs.Many of these businesses need to continually adapt to new ways of obtaining thermal energy, since many variables interfere with the results they achieve through the use of equipment and different types of fuels used to generate the thermal energy they need to perform their activities competitively, in addition to respecting environmental legislation and meeting consumer desires for products and services that meet their expectations of good socio-environmental practices.

[002] The generation of heat energy through pellet combustion is considered by the market to be the most advanced biomass consumption system. In addition to replacing fossil fuels, pellets are a trend because they reduce costs and are a sustainable, clean, and renewable source that generates wealth and development. To strengthen this trend of using this type of fuel, the market needs pellet burners with various characteristics related to flexibility of use, since the types of furnaces and their applications are varied. Therefore, pellet combustion equipment needs to adapt easily to many types and sizes of furnaces. Petition 870210057189, dated 06 / 24 / 2021, page 7 / 21 2 / 15

[003] Although the use of thermal power generation equipment through pellet burning is widely used in several developed countries, Brazil is still a market with a low level of use of this method. STATE OF THE ART

[004] There are technologies currently available on the market that meet the demands for heating furnaces through energy generation using pellet fuel. Many of these, through burners adapted to furnaces that are in operation with other types of fuels, as is the case with the patents and processes identified in the INPI databases themselves: BR 202014027664-0, BR 20 2012 031550-0, PI 1106173-1, MU8702268-0, PI 0202296-6. All these technologies, quite focused on the fuel combustion process, although aiming to replace other types of fuels in furnaces with the most varied uses and in many sectors, do not present characteristics that facilitate this replacement, as they do not focus on the mobility of pellet combustion equipment, presenting technologies that are poorly adaptable to furnaces that already exist on the market, and even less so to those that are already in operation with other types of fuels.Currently available on the market are static pellet burners, which require the burner to be incorporated into the furnace. The technology focuses on transforming the furnace to operate with the new system, losing the characteristics it had when operating with the previous fuel. These pellet burner models need to be installed and incorporated into the furnace, where they remain without the possibility of movement, making it difficult for the equipment to operate with any fuel other than pellets.

[005] The “PORTABLE AUTOMATIC PELLET BURNER WITH REMOTE ELECTRONIC MONITORING” presents a differentiated solution compared to what is already known in the state of the art. This technology focuses on the mobility of fuel systems, adopting concepts that facilitate the coupling and uncoupling of the pellet burner to the furnaces. It is a portable, compact piece of equipment with an internal silo that operates on casters. Petition 870210057189, dated 06 / 24 / 2021, page 8 / 21 3 / 15 installed on vertical tubular telescopic metal columns, which have height adjustment to facilitate their coupling and uncoupling from the furnace. It is worth highlighting that these requirements are decisive for many entrepreneurs to adopt the pellet combustion system, since a large number of businesses do not have the physical space that allows the incorporation of the combustion system into the furnaces they use, as many use fuels such as gas, electricity, etc.

[006] Maintaining the furnace as a multi-fuel furnace is also an important attribute, because if it becomes necessary to operate with another type of fuel besides pellets, the furnace becomes more flexible in its use and the solutions for adapting to logistics and fuel costs are more favorable to the business. In this regard, the “PORTABLE AUTOMATIC PELLET BURNER WITH REMOTE ELECTRONIC MONITORING” offers the solution of easy decoupling and movement. It is a compact piece of equipment, with the dimensions of a cabinet, that operates on mobile and vertically adjustable casters, facilitating its movement and storage in small spaces available in users' facilities.

[007] The technologies available on the market, with regard to the control and monitoring of pellet burner operations, are simple commands, activation by operators at the machine and on-site monitoring. The present invention presents innovative solutions that enable remote activation, control and command, being the most technologically advanced on the market within power ratings up to 200,000 kcal / hour, being the only industrial pellet burner to have Industry 4.0 integration, as there is no equipment with these characteristics that allow remote access.

[008] With regard to the commands, controls, actuations and monitoring of the functions of a pellet burner, important points of its operation can be compared with the technologies available on the current market and with the innovations of the present invention. In the technology available in the state of the art, the fire must be started manually and the operator must visually check, whereas the technology provided by the “PORTABLE AUTOMATIC PELLET BURNER WITH Petition 870210057189, dated 06 / 24 / 2021, p. 9 / 21 4 / 15 "REMOTE ELECTRONIC MONITORING": The ignition of the fire is done automatically and does not require monitoring. With current technology, the fire has a pre-programmed time to ignite, and after this time the burner moves to the next phase. Even if the pellets have not started burning, filling the combustion chamber with unlit pellets, the machine does not identify the unburned fuel and ends up obstructing the passage of pellets, causing problems in the equipment. The technology of the present invention monitors the flame ignition in real time and only releases the pellet feeding phase if a fire is detected; otherwise, it emits alerts and enters the shutdown process to prevent obstruction of the combustion chamber by excess fuel inside.The technology currently available on the market does not identify a lack of pellets in the fuel injection system, maintaining the combustion process even without pellets. In such cases, the burner stops heating without the operator noticing. The technology of the present invention, however, identifies a lack of pellets, alerting the operator audibly and visually to add more pellets to the equipment's silo. In current state-of-the-art technology, pellet burners have proportional, mechanical feed and air controls, depending on the operator's expertise, who often finds it difficult to adjust and is left unaware of the power output due to a lack of information.With the technology presented in this invention, the control of pellet and proportional air feed is automated, ensuring combustion efficiency, and the operator knows exactly the power being used based on the information the system provides on the equipment's monitoring display. Technologies available in commercially available pellet burners do not allow for the emission of warning signals for electronic problems in their peripherals, nor do they provide consumption information or activity history. They are also not prepared for remote access and monitoring. In the case of this invention, the developed technology enables the emission of alerts from all its peripherals (motors, sensors), consumption information, and activity history, all of which can be accessed remotely.

[013] The design of the “PORTABLE AUTOMATIC PELLET BURNER WITH REMOTE ELECTRONIC MONITORING” comprises a structure formed by square metal tubes, constructed of stainless steel or carbon steel, in the form of a cabinet, with integral closure by fairings constructed of stainless steel or carbon steel metal sheets (01), and in this housing are incorporated the following equipment and resources: Metal silo with movable lid for pellet supply (09), constructed of stainless steel or carbon steel, conveyor screw A (07) which has the purpose of removing the pellet fuel from the silo and injecting the fuel into the conveyor screw B (08), this conveyor having the function of injecting the pellet fuel directly into the combustion chamber (10), and both conveyor screws are driven by two geared motors, driven by motor A (3.10) and motor B (4.8).The system is equipped with two exhaust motors, one (C) with the function of injecting and controlling the volume of oxygen flow in the combustion chamber, and the other (D) with the additional function of carrying out greater heat movement within the furnace, normally used in large-scale equipment where it is necessary to better spread the generated heat. The combustion chamber, equipped with a grate and electronically controlled, receives fuel and oxygen, generating energy that is conducted to the furnace. The grate is fixed to the base of the structure and projects through the side to reach the coupling opening. The assembly is equipped with a heating element, air chamber, 12-volt switched-mode power supply for low-voltage operation, and a battery to keep the system running in the event of a power outage.The monitoring and control systems include switched-mode power supplies, a photoelectric sensor, a flame sensor, a temperature sensor, and a dedicated electronic controller for the equipment.

[014] All mechanisms and controls are activated and commanded by a panel with an HMI - Home Machine Interface system (12), which aims to allow all equipment commands to be performed electronically and automatically, and to enable its remote electronic monitoring. The design of Petition 870210057189, dated 06 / 24 / 2021, page 14 / 21 9 / 15 “PORTABLE AUTOMATIC PELLET BURNER WITH REMOTE ELECTRONIC MONITORING” also aims to meet the concept of equipment aligned with Industry 4.0, and to this end incorporates a wide range of controls and functions, as described below:

[015] Equipment Startup Step: When the main switch is turned on, electricity is supplied (110 or 220 volts alternating current) to the power sources and electronic controller, which initiate battery charging and also (12 volts direct current) to the electronic controller, and starts motor “C” at low power. The electronic controller checks the battery status to verify charge and connection, the alternating current status to see if the machine is plugged in, the pellet sensor status to see if the silo is loaded (if the pellet sensor menu is selected in the manual, the system skips the pellet check); the flame sensor status to check if there is a fire; and the status of motors “A, B, C, D”. If any of these checks are identified as negative, the equipment will be unable to start the work process.If the flame sensor status is positive or the menu setting is manual, motor “C” starts at medium power and the work process becomes available to start, if the operator wishes. All this data can be sent to the server to generate a history, if the equipment is connected.

[016] Menu Levels for system administration: Consists of 3 menu levels: Level 1: For Operator function, no password required, has access to all operator level menus - Level 2: For Maintenance function - Production Leader requires client password and has access to operator and client menus - Level 3: For Manufacturer, has access to all menus.

[017] Menu 1 - Temperature Control - In this menu, the operator selects the desired temperature for the equipment. Menu 2: Recipes - In this menu, the operator can select cooking recipes for the selected products, ramps, and heating times. Menu 3: Offset - In this menu, the programmer or manufacturer selects how many degrees before reaching the programmed temperature the equipment should cut power to prevent exceeding the programmed temperature. Menu 4: Temperature Offset - In this menu, the Petition 870210057189, dated 06 / 24 / 2021, page 15 / 21 10 / 15 programmers or manufacturers can perform a temperature calibration by referencing an external temperature controller or meter, adjusting the temperature by up to 40 degrees more or less.

[018] Menu 5: Flame sensor - In this menu, the programmer or manufacturer can select flame sensor in manual mode (for cases where the sensor is not working; in this way, the controller works with different times in the fire ignition stage, performs the work process without the flame sensor, but does not guarantee ignition, as the operator must monitor it) and automatic mode, where the sensor monitors the flame and ensures ignition before proceeding to the work stage - Menu 6: Pellet sensor - In this menu, the programmer or manufacturer can select pellet sensor in manual mode (this mode will cause the controller to always indicate that there are pellets inside the silo even if there are not), or automatic mode, where the sensor monitors the pellet stock level in the silo.

[019] Menu 7: Burn Control - In this menu, the programmer or manufacturer selects internal temperature control (causes temperature control to be done through the equipment's own electronic controller, via a temperature sensor), or can select external temperature control (causes temperature control to be done through an external controller, which sends a 220v signal whenever temperature is needed).

In this menu, the equipment can be programmed for hibernation by selecting the "Yes" or "No" options on the control panel. This function is used when the equipment operates at low power for more than an hour and the ambient temperature continues to fluctuate significantly due to external weather conditions (e.g., poultry houses in summer are practically hot every day, but if it gets cold one day, the system automatically starts the equipment without the need for operator presence or any intervention). Although the controller enters hibernation and its display turns off, the temperature sensor remains active in the background, and as soon as a temperature change is detected, it restarts the entire process.To exit hibernation mode, simply press the "S" key and the system will turn on the display to the home screen.

[022] Menu 15: Turbo Burn - In this menu, the programmer or manufacturer configures manual or automatic turbo burn. If it is manual, the operator must activate it manually.

[026] Stage Starting the Fire - When the PORTABLE AUTOMATIC PELLET BURNER WITH REMOTE ELECTRONIC MONITORING is switched on, the system reads and verifies the peripherals and the equipment is ready to start the work process, waiting for the operator to start the work process, which begins by pressing the S key. Its display shows the information "Starting Fire" and "Loading Pellets", and the system turns on the heating element. Petition 870210057189, dated 06 / 24 / 2021, page 18 / 21 13 / 15 Fire start: Pellet injection motor 1 (one) starts, and this motor shuts off 8 (eight) seconds after pellet injection motor 2 shuts off. Combustion motor C starts, and after 1 (one) second, the pellet metering motor starts, and this motor shuts off after 12 (twelve) seconds of operation. An auxiliary motor also starts. At this moment, TI starts a 480-second background counter, which is the time limit for the fire to ignite. Otherwise, the system emits an alert indicating that the fire has not ignited. If there is an interruption of 5 (T2_l) seconds or more continuously, the 30 (T2) second counter will reset and start again. After 30 (T2) continuous seconds have elapsed, the heating element will turn off T2_l, reset, and stop counting. A new 30 (T3) second countdown begins for the fire to become consistent.If the flame sensor is set to automatic (T2 and T3 are multiplied by 1), if it is set to manual (T2 and T3 are multiplied by 4), upon completion of the T3 time, it proceeds to the next stage. T1, T2, T2_1, and T3 are reset, and the counters stop counting. The automated firing stage begins.

[027] Automated Burning Stage: Through the Burning Control Menu, configured as external control, the electronic controller monitors the 220v power input and, when the signal is identified, enters the high power burning cycle configured according to the High Power Menu + Reserve Power Menu, with the sum only occurring if the High Power Menu is at 100%. The cycle length is set in seconds and defined by the Burner Model Menu. The display shows an external control message and a resume message if the signal is not identified. The equipment enters the low power burning cycle configured according to the Low Power Menu; the display shows an external control message and a Stabilizing message.If the Burn Control Menu is configured as internal control, the Temperature Control Menu and Delay Menu are monitored, and the high-power burn cycle remains active as long as the Temperature Control Menu shows results higher than the temperature read by the temperature sensor. The display shows a temperature message from the sensor and a resume message. If the temperature sensor reading is between... Petition 870210057189, dated 06 / 24 / 2021, page 19 / 21 If the temperature reading from the temperature sensor is higher than the temperature programmed in the Temperature Control Menu and the temperature from the Temperature Control Menu are lower than the temperature from the Offset Menu, the active firing cycle is the offset cycle, the display shows the sensor temperature message and the message “Offset”. If the temperature reading from the temperature sensor is higher than the temperature programmed in the Temperature Control Menu, the low power firing cycle is activated according to the Low Power Menu setting, the display shows the sensor temperature message and the message “Stabilizing”.

[028] Safe Shutdown Process: The safe shutdown process follows these steps: If no 110~220 voltage signal is detected for 15 (T4) seconds, the process begins and the message “Safe Shutdown” appears on the display. The time count in minutes starts at 20 (T5) minutes, which is the cycle time of the safe shutdown process. Then MOTOR “A” stops feeding pellets, MOTOR “B” continues running for 1 minute to ensure complete removal of pellets from the transport system, and after this time the system shuts down. MOTOR “C” remains at 60% PWM for 6 (T6) minutes, and MOTOR “D” remains at 100% PWM. After T(6) is completed, the PWM of MOTOR “C” is at 100% and the information on the display changes to “Cooling System”, while the time counter continues counting. After T(5) is completed, the display turns off and waits for a new system power-on command, remaining connected to the control unit via Wi-Fi.If, during the shutdown process, the machine receives the "Turn On Again" command, MOTOR "C" changes PWM to 60% and MOTOR "D" remains at PWM to 100% and enters the "Starting Fire Ignition" stage.

[029] Pellet Shortage Alert Process - During the Equipment Startup stage, if the silo is not filled, the display shows the message “Pellet Shortage” (F2). After filling, the process continues. While the silo is not filled, the fault continues to appear on the display and an alarm is activated cyclically with 3 beep pulses and a pulse interval of 300ms on and 300ms off, with the interval between each 3 pulses being 3 seconds. In the “Automated Burning” operation, the display shows the message “Pellet Shortage” (F2). The automated burning process continues and the Petition 870210057189, dated 06 / 24 / 2021, page 20 / 21 / 15: The temperature message is replaced by the message "Lack of Pellets" and an alarm is activated with 3 beep pulses with a pulse interval of 300ms on and 300ms off, and the interval between each 3 pulses is 3 seconds. In the safe shutdown process, the photoelectric sensor that monitors the lack of pellets inside the silo is not monitored.

[030] Active recipe menu process - In this process, the automated burning stage is changed and the equipment follows specific customer settings such as burning times and power levels, which can be configured via the equipment controller or via a mobile application or web application.
