Description

Technical Field

[0001] This utility model belongs to the technical field of heating furnace equipment accessories, specifically relating to a tubular heating furnace burner assembly with automatic ignition function. Background Technology

[0002] Tubular furnaces are process heating furnaces used in industries such as petroleum refining, petrochemicals, coal chemicals, tar processing, and crude oil transportation. The heated substances are gases or liquids flowing inside the tubes, and these are often flammable and explosive, requiring harsh operating conditions. They also require long-term, uninterrupted operation, with direct heating via flame. The burner is the heat-generating device that atomizes the fuel and mixes it with air for combustion. Currently, in production, when the burner nozzles need to be ignited, workers typically use a hand igniter to ignite each nozzle individually through the inspection port at the bottom of the burner. Due to differences in personnel skill levels, this often results in long ignition times and low ignition efficiency, causing fluctuations in the furnace outlet temperature and, in severe cases, affecting the stable and continuous operation of the unit.

[0003] Therefore, it is necessary to design a tubular furnace burner assembly with automatic ignition function, which can quickly and timely ignite multiple burners when the burner nozzle needs to be ignited, ensuring a stable furnace outlet temperature and avoiding fluctuations in production equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model proposes a tubular heater burner assembly with automatic ignition function to solve the technical problem that when the burner nozzle needs to be ignited in actual production, the long time and low efficiency of manual ignition affect the operation of the heater and cause fluctuations in process parameters such as flow rate, temperature and pressure.

[0006] (II) Technical Solution

[0007] To address the aforementioned technical problems, this utility model proposes a tubular furnace burner assembly with automatic ignition function. This assembly includes a main control panel and multiple burners. The main control panel is equipped with multiple burner control and display components. Each burner control and display component includes an ignition switch and a combustion gas regulating valve, and each component is connected to its corresponding burner. Each burner includes a pulse igniter, a thermocouple solenoid valve, an ignition probe, and a burner nozzle. When ignition is required, the ignition switch is activated, and current flows through the pulse igniter to the ignition probe, forming an electric spark. The fuel gas regulating valve is opened, and the thermocouple solenoid valve opens, allowing fuel gas to be ejected through the burner nozzle. Upon contact with the electric spark released by the ignition probe, combustion occurs.

[0008] Furthermore, each burner control and display unit includes a flame combustion status indicator light to display the combustion status of the fuel gas.

[0009] Furthermore, each burner group includes multiple ignition probes and burner nozzles.

[0010] Furthermore, multiple burner nozzles surround the outer periphery of multiple ignition probes.

[0011] Furthermore, each burner group includes a thermocouple induction needle, which converts thermal energy into electrical energy to ensure that the thermocouple solenoid valve is in the normally open state. When the burner nozzle is extinguished, the thermocouple induction needle transmits a signal to the thermocouple solenoid valve, which immediately closes to stop the fuel gas from entering the heating furnace.

[0012] Furthermore, each burner group includes a thermocouple induction needle.

[0013] Furthermore, the thermocouple sensing needle is positioned inside the multiple ignition probes.

[0014] (III) Beneficial Effects

[0015] This utility model proposes a tubular heater burner assembly with automatic ignition function, including a main control panel and multiple burners. The main control panel is equipped with multiple burner control and display components. Each burner control and display component includes an ignition switch and a combustion gas regulating valve. Each burner control and display component is connected to the corresponding burner. Each burner includes a pulse igniter, a thermocouple solenoid valve, an ignition probe, and a burner nozzle.

[0016] After the ignition switch is activated, the pulse igniter discharges, and the ignition probe generates an electric spark near the burner nozzle. Simultaneously, the fuel gas regulating valve opens, completing ignition and saving ignition time. This increases the success rate of ignition on the first attempt, ensuring the stability of the heating furnace process parameters and preventing fluctuations in process parameters such as flow, temperature, and pressure caused by prolonged failure to ignite, which could lead to substandard product quality. By adding a thermocouple induction needle, the thermocouple solenoid valve can be immediately cut off when the heating furnace is shut down, protecting the safe and stable operation of the device. This invention has the advantages of simple operation, easy construction, easy maintenance, easy modification, low cost, and no impact on normal production. Attached Figure Description

[0017] Figure 1 This is a schematic diagram showing the composition and working principle of the burner assembly of the tubular heating furnace of this utility model. Detailed Implementation

[0018] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0019] This embodiment proposes a tubular heater burner assembly with automatic ignition function, the composition and working principle of which are as follows: Figure 1 As shown, it mainly includes the main control panel 1 and multiple burners.

[0020] The main control panel 1 is equipped with multiple sets of burner control and display components. Each set of burner control and display components includes an ignition switch 2, a flame combustion status indicator 3, and a combustion gas regulating valve 4. Each set of burner control and display components is connected to the corresponding burner.

[0021] Each burner group includes a pulse igniter 5, a thermocouple solenoid valve 6, an ignition probe 7, a thermocouple induction needle 8, and a burner nozzle 9. In actual production, when the heating furnace needs to be ignited after being shut down, the ignition switch 2 is activated. Current flows through the pulse igniter 5 to the ignition probe 7, forming an electric spark on the ignition probe 7. At this time, the fuel gas regulating valve 4 is opened, and the thermocouple solenoid valve 6 opens. Fuel gas is sprayed out through the burner nozzle 9, and combustion occurs upon contact with the electric spark released by the ignition probe 7. The combustion status is displayed by the flame combustion status indicator light 3.

[0022] After ignition, the fuel gas supply is controlled to remain consistent with the previous level by adjusting the combustion gas regulating valve 4 in each burner group, ensuring no fluctuation in the furnace outlet temperature and stable process parameters such as system flow, temperature, and pressure. Simultaneously, each burner group converts heat energy into electrical energy through its respective thermocouple induction needle 8, ensuring the thermocouple solenoid valve 6 remains normally open. If the burner nozzle 9 extinguishes due to any problem, the thermocouple induction needle 8 transmits a signal to the thermocouple solenoid valve 6, which immediately closes, stopping fuel gas from entering the furnace and ensuring the safety of the device.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
