Description

Technical Field

[0001] The invention relates to the technical field related to burners, and in particular to a high-efficiency burner for a biomass boiler. Background Art

[0002] Boiler burner is a device that provides heat to the boiler. When using the burner to burn biomass fuel, a large amount of biomass will accumulate and eventually form impurities. After the device is used for a long time, these impurities will affect the subsequent combustion efficiency, which will not only lead to incomplete combustion of the accumulated biomass and waste of fuel, but also produce a large amount of pollutants due to incomplete combustion, thus forming thick smoke and polluting the environment.

[0003] In order to overcome the above-mentioned defects, prior art 1 (application number 202322026001.0, Chinese patent application date 2023-07-31) a high-efficiency biomass boiler burner, including a transport base, a burner is fixedly installed on the top of the transport base, a partition plate is fixedly installed on one side of the burner, a rotating rod is rotatably installed on one side of the partition plate, and a full combustion mechanism is detachably installed on the rotating rod. By driving the igniter on the bottom side of the burner, the biomass is efficiently burned, and at the same time, the servo motor on one side drives the half gear to rotate, and the half gear ring rotating with the half gear will drive the rotating rod to rotate, so that the filter cover on one side of the rotating rod drives the burning material to flip, so as to avoid the biomass from being unable to burn fully inside the filter cover. When the half gear ring is separated from the half gear, the filter cover will automatically reset due to the first spring sleeved on the rotating rod, and after waiting for the half gear ring to mesh with the half gear for the second time, the filter cover can be repeatedly flipped left and right inside the burner, which greatly improves the combustion of biomass inside the filter cover;

[0004] There is also prior art 2 (Chinese patent with application number 201910328597.5 and application date 2019-04-23), a self-controlling temperature biomass boiler, which belongs to the field of biomass boilers and includes a furnace body, a burner, a smoke hood, a heat exchange box, a water temperature sensor and a controller. A furnace is provided inside the furnace body, and a furnace wall is provided with a furnace port connected to the furnace. The burner includes a gas collecting cylinder arranged in the furnace and a combustion cylinder arranged in the furnace port. The axial outer side of the gas outlet end of the combustion cylinder forms a flame zone. The smoke hood is connected to the furnace body. The heat exchanger hood is arranged outside the flame zone and is provided with a smoke exhaust port. The inner cavity of the heat exchanger box is a flue. The air inlet end is connected with the smoke exhaust port, and the exhaust end is connected with a smoke exhaust fan. The box wall is provided with a first water jacket, a water inlet pipe and a water outlet pipe. The water temperature sensor is arranged in the first water jacket or the water outlet pipe. The controller is electrically connected with the water temperature sensor and the smoke exhaust fan respectively. The controller monitors the water temperature through the water temperature sensor. When the water temperature is too low, the controller controls to increase the exhaust volume of the smoke exhaust fan, so as to suck more high-temperature smoke into the flue and quickly increase the water temperature of the first water jacket.

[0005] And prior art 3 (Chinese patent with application number 202223399638.6 and application date 2022-12-19) A high-efficiency biomass boiler burner, comprising a combustion barrel, the front end of the combustion barrel is an opening, a grid plate is arranged in the opening, a bellows and a feeding mechanism are arranged on the top of the combustion barrel, the bellows is connected to the rear end of the combustion barrel through a ventilation pipe, an ash storage box is arranged below the front end of the combustion barrel, a connecting port is arranged between the ash storage box and the combustion barrel, a motor 2 and a front door are arranged on the side of the ash storage box, a drive shaft of the motor 2 is connected to a drum located in the ash storage box, the drum is embedded in the connecting port, the outer cylindrical surface of the drum is tangent to the inner cylindrical surface of the combustion barrel, and the side wall of the combustion barrel is provided with a telescopic ignition device aligned with the connecting port, which has certain stirring and ash discharge functions for the burning biomass, effectively improves the contact between the biomass and the air, and improves the combustion efficiency.

[0006] Although the existing technology can improve the combustion efficiency by turning the biomass and controlling the exhaust volume, during the working process, improving the combustion efficiency by controlling the air volume requires the installation of additional structures, which increases the overall installation cost. If the biomass is poured into the burner as a whole, if the amount of biomass introduced is too small, it is easy to cause insufficient fuel supply in the boiler, thereby reducing the overall efficiency of the boiler. If the amount of biomass introduced is too large, it will not only cause uneven heat output and affect the stable operation of the boiler system, but also easily lead to incomplete combustion of the biomass, resulting in fuel waste, thereby increasing the cost of combustion.

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original high-efficiency burner for biomass boilers. Therefore, we proposed a high-efficiency burner for biomass boilers that can solve the above problems well. Summary of the invention

A partition 8 is arranged inside the combustion box 7, and a temporary storage box 5 is installed at the bottom of the feed pipe 3. The side end of the temporary storage box 5 is connected to a conveying pipe 6, and a processing box 9 is arranged at the bottom of the conveying pipe 6. A gas pipeline 10 is installed at the side end of the combustion box 7. The biomass is introduced into the combustion chamber 1 through the cooperation of the feed hopper 2 and the feed pipe 3. The biomass fuel falls into the temporary storage box 5 through the feed pipe 3, and the biomass fuel is transported to the combustion chamber 1 through the conveying pipe 6. At the side end of the combustion box 7, the combustion box 7 is blocked by a partition 8, and the biomass fuel that falls into the bottom of the combustion box 7 through the processing box 9 is conveniently burned using an ignition component, so that the burning flame and gas are output through the gas pipeline 10, thereby improving the overall combustion efficiency and reducing the problem of increased overall cost due to the need for additional installation structures. The drive motor 11 is turned on, and the drive motor 11 drives the rotating shaft 12 to rotate, so that the rotating shaft 12 drives the full gear 14 to rotate through the half gear 13, so that the full gear 14 drives the rotating rod 15 to rotate, so that the full gear 14 conveniently drives the baffle 4 to rotate, so that the biomass fuel can fall into the temporary storage box 5 through the feed pipe 3, and a torsion spring 16 is arranged on the outside of the rotating rod 15.

The push plate 22 pushes the biomass fuel inside the temporary storage box 5 to the conveying pipe 6 for conveying operation, and the movable plate 19 is connected to the side end of the temporary storage box 5 by the first spring 20. Therefore, after the first eccentric wheel 18 continues to rotate and leaves the surface of the movable plate 19, the movable plate 19 recovers its initial position through the cooperation of the first spring 20, which is convenient for moving again. The whole is used in conjunction with the drive motor 11, which reduces the problem of cost increase caused by the need to set up more drive structures, and is convenient for pushing the biomass fuel, which can effectively avoid the problem of fuel blockage in the conveying pipe 6, facilitates the full combustion of the fuel, and greatly improves the overall service life. The dual-axis motor 24 inside the auxiliary box 23 is opened, and the dual-axis motor 24 drives the stirring member 26 to rotate through the rotating shaft 25, so that the stirring member 26 mixes the introduced fuel, which not only makes the later oxygen supply more uniform, but also makes the overall combustion sufficient, thereby improving the overall combustion efficiency.
