Description

Technical Field

[0001] This invention relates to the field of burner technology, and more specifically to a combined burner for a vertical boiler. Background Technology

[0002] With the rapid development of industry and the continuous growth of energy demand, boilers, as important thermal power equipment, play an indispensable role in industrial production and daily life. Vertical boilers are widely used in small-scale industrial production and civil heating due to their advantages such as compact structure, convenient installation and small footprint. The core of the combined burner lies in the design of its combustion chamber and fuel supply system.

[0003] In the existing technology, combined burners used in vertical boilers are difficult to accurately adjust the fuel quantity according to different operating conditions, resulting in unstable combustion efficiency. When it is necessary to increase or decrease the combustion power, it is impossible to make a quick and accurate adjustment, resulting in energy waste or failure to meet actual needs. It is also difficult to dynamically adjust the air supply according to the fuel quantity and combustion state, which can easily lead to insufficient air supply, resulting in incomplete combustion of fuel, or excessive air supply, which reduces combustion temperature and efficiency. Summary of the Invention

The conveyor frame 305 is equipped with a screw conveyor rod 307 fixedly connected to the end. A feed hopper 308 is located at the center of the upper end face of the conveyor frame 305, and a material box 309 is located at the center of the upper end face of the feed hopper 308. One end of the material box 309 passes through the inner wall of the box body 1 and leads to the upper end of the box body 1. Stabilizing blocks 310 are provided at the center of both side walls, the center of the front face, and the center of the rear face of the material box 309. A discharge port 311 is inclined at the center of the lower end face of the conveyor frame 305. Fuel is stored in the material box 309. The fuel enters the conveyor frame 305 through the feed hopper 308.

The treated air is then delivered to the burner 402 by the first blower pump 401, where it mixes with the fuel delivered from the discharge port 311. The igniter 403 at the center of the burner 402 generates an ignition source, igniting the fuel and air mixture and initiating the combustion process. The burner 402 is responsible for further organizing and ensuring the stable progress of combustion.

[0036] In this embodiment, a combustion structure 5 is provided at the center of the combustion chamber 6. The combustion structure 5 includes two baffles 501, which are respectively located at the front and rear of one side of the lower inner wall of the combustion chamber 6. A top plate 502 is provided at the center of the upper surface of the two baffles 501. A waste box 505 is provided on the lower inner wall of the combustion chamber 6 between the two baffles 501. A first filter plate 503 is provided at the upper center of the waste box 505. A second filter plate 504 is provided at the side of the center of the upper surface of the first filter plate 503. A combustion rack 506 is provided inside the combustion chamber 6 on one side of the two baffles 501. A flow chamber 507 is provided at the center of the upper surface of the combustion rack 506. A discharge port 508 is provided at the side of the center of the upper surface of the combustion chamber 6. Pressure relief pipes 509 are provided on both sides of the upper rear surface of the combustion chamber 6. A second blower pump 510 is provided on one side of the upper front surface of the combustion chamber 6. An exhaust port is provided at the other side of the center of the upper surface of the combustion chamber 6. 511. Adjusting gates are provided at the upper center of the outer walls of the two pressure relief pipes 509. The combustion structure 5 inside the combustion chamber 6 optimizes the combustion process. The two baffles 501 and the top plate 502 create a stable combustion space. The first filter plate 503 and the second filter plate 504 inside the waste box 505 filter and collect the waste residue generated during combustion. The second blower pump 510 may further supplement and adjust the amount of combustion air to ensure complete combustion. The exhaust gas generated during combustion is discharged through the exhaust port 508. During the discharge process, some purification treatment is carried out on the exhaust gas discharge path. In addition, when the exhaust gas pressure is too high, part of the gas is discharged through the exhaust port 511. The discharge pressure and other parameters can be adjusted through the adjusting gates inside the two pressure relief pipes 509. When the pressure inside the combustion chamber 6 is too high, the pressure is released and adjusted through the pressure relief pipes 509 to ensure the safe and stable operation of the equipment.

[0037] Implementation Plan: Fuel is stored in hopper 309 and fed into conveyor frame 305 via feed hopper 308. Larger fuel particles can also enter the conveying process during coal combustion. Servo motor 306 drives screw conveyor 307 to rotate, pushing fuel along conveyor frame 305 from feed hopper 308 to discharge port 311, and then into burner 402. PLC controller 304 can control parameters such as conveying speed and time according to instructions, adjusting the amount of fuel entering burner 402. If increased combustion power is required, PLC controller 304 increases the speed of servo motor 306 to increase fuel delivery. External air is introduced through the air intake. The air enters through the intake frame 405. The filter screen 407 of the intake frame 405 can intercept dust and large particulate impurities, the absorbent cotton 408 absorbs small particles and some water vapor, and the activated carbon 409 absorbs harmful gases and odors, purifying the air. In smoggy weather, this can effectively reduce pollutants entering the burner 402. The treated air is pressurized and delivered to the burner 402 by the first fan pump 401 and fully mixed with the fuel sent from the discharge port 311, providing sufficient oxygen for combustion. The speed of the first fan pump 401 is controlled by the PLC controller 304 to avoid insufficient air supply, incomplete combustion of fuel, or excessive reduction in combustion efficiency.

[0038] The igniter 403 inside the burner 402 generates an ignition source, igniting the fuel-air mixture and initiating combustion. The igniter 403 ignites the fuel-air mixture, starting the combustion process. The baffle 501 and the top plate 502 inside the combustion chamber 6 form a relatively stable combustion space, which is conducive to flame concentration and heat accumulation, improving combustion efficiency. In a limited space, combustion is more intense and heat loss is less. The first filter plate 503 and the second filter plate 504 inside the waste box 505 filter and collect the waste generated by combustion in layers, preventing the waste from entering the next stage and affecting equipment operation or clogging the pipeline. The second fan pump 510 supplements the air volume of the gas generated after combustion, adjusting the air distribution in the combustion chamber 6. The exhaust gas is discharged through the exhaust port 508. When the exhaust gas flows, some gas is released through the exhaust port 511. The regulating gate on the outside of the pressure relief pipe 509 can regulate the discharge pressure. When the pressure in the combustion chamber 6 is too high, the gate is opened, and the pressure is released through the pressure relief pipe 509 to maintain stable equipment pressure and ensure safe operation.
