[0002] A biomass burner is a device used to convert biomass materials such as wood, straw, wood chips, pellets, etc. into thermal energy. It can be used for heating, power generation or other industrial processes to meet thermal energy needs. Biomass burners usually use combustion or gasification technology to burn or gasify carbon, hydrogen, oxygen and other elements in biomass materials, releasing heat energy and producing combustion exhaust gas. Biomass burners are widely used to replace traditional fossil fuels to reduce the impact on the environment and promote the use of renewable energy.

[0003] At present, there are still some problems in the use of biomass burners. For example, the biomass is not fully burned due to the influence of air, resulting in low biomass utilization efficiency. Because the air is supplied from the ash layer, the highest combustion temperature is in the combustion layer, and the temperature of the combustion space above the reduction layer cannot meet the complete combustion conditions of the volatile matter, thus forming thick smoke, causing incomplete combustion, and causing a large amount of calorific value of solid combustibles to be lost, which greatly wastes energy.

[0040] Example 3

[0041] like Figure 3 and Figure 5 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, a water window 11 is opened on one side of the water tank 1, and the water window 11 is used to observe the water level in the inner cavity of the water tank 1.

[0050] When the biomass fuel is burned out, the ash will fall into the bottom wall of the inner cavity of the ash plate 51, and then accumulate in the inner cavity of the ash plate 51. When the device stops running and cools down, the tap water in the inner cavity of the water tank 1 can be transported to the inner cavity of the water diversion box 44 through the water pump 41 through the water pipe 42, and then the tap water can be transported to the inner cavity of the ash plate 51 through the cooperation of a plurality of diversion pipes 43 and water holes 53, so that the ash accumulated in the inner cavity of the ash plate 51 can be washed, and then the ash accumulated in the inner cavity of the ash plate 51 can be washed away. The ashes in the water will flow from the ash outlet trough 52 into the dust box 23 under the flushing of tap water, and then pass through the filter in the dust box 23 to filter the ashes in the tap water. The filtered tap water will flow back into the water tank 1 again, and the filtered ashes will fall into the dust box 23. Then the staff can slide the dust box 23 out of the connecting frame 22 to process the ashes in the dust box 23. After processing, the dust box 23 can be reset.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
