[0012] As a further technical solution of the present invention, a guide pipe is fixedly provided on the upper end surface of the main box body, the other end of the guide pipe passes through the water storage chamber, the other end of the guide pipe is fixedly connected to the heat dissipation pipe, and two groups of left-right symmetrical exhaust pipes are fixedly provided on the left and right end surfaces of the guide pipe.

[0013] As a further technical solution of the present invention, multiple groups of oxygen pipes are fixedly provided on the left and right end faces of the main box body, which are symmetrical in front and back.

Multiple groups of nozzles are fixedly provided on the left and right walls of the combustion chamber, which are evenly distributed in the front and back and correspond to the valves one by one.

[0014] The beneficial effects of the present invention are:

[0015] 1. The biomass in the combustion chamber of the present invention begins to burn at a high speed. The heat generated at this time will be transferred to the outside through the main box body. However, since the heat needs to accumulate and pass through the main box body to heat the water in the water storage chamber, the high-temperature gas generated by the combustion will enter the heat dissipation pipe through the guide pipe, and then be discharged through the exhaust pipe. At this time, the gas will preheat the gas in the water storage chamber in advance, further raising the water temperature in advance, thereby increasing the efficiency of heat penetrating the main box body and reducing the heating time of the water in the water storage chamber, thereby ensuring that the heat can be quickly transferred. Moreover, since the heat dissipation pipes are all in the water in the water storage chamber, the heat of the discharged high-temperature gas will also be fully absorbed, thereby ensuring that the high heat generated by the biomass combustion boiler is fully and thoroughly absorbed, thereby ensuring the practicality of the biomass combustion boiler.

[0016] 2. The pneumatic cylinder of the present invention starts to telescope, thereby driving the lifting frame, the push plate and the push rod to start moving up and down along the guide hole, thereby creating sufficient gaps between the accumulated burning biomass, further preventing incomplete combustion, and when the valve starts to start, driving the oxygen transported by the oxygen pipe to spray from the nozzle into the combustion chamber, and further enter the gaps of the burning biomass, thereby ensuring sufficient and thorough combustion of the biomass, thereby ensuring maximum utilization of resources.

[0017] 3. The present invention fills sufficient biomass in the combustion chamber, and biomass can still be added in the storage chamber. As the biomass in the combustion chamber burns, the biomass will turn into ashes, and the space in the combustion chamber will be reduced. As a result, the biomass in the storage chamber will be filled downward under the influence of gravity, which extends the combustion time of the biomass, thereby changing the number of times that the existing timed filling is required, thereby ensuring the practicality of the biomass combustion boiler.

[0018] 4. The push rod of the present invention begins to reset, and the ashes adhered to the outer cylindrical surface of the push rod will be cleaned by the positioning frame. At this time, the ashes will be in the combustion chamber, and the two groups of threaded motors symmetrically on the left and right begin to start, thereby driving the threaded screw to start rotating, and then driving the threaded slider and the scraper and the sliding frame to start moving forward along the inner wall of the combustion chamber. At this time, the ashes adhered to the inner wall of the combustion chamber are quickly cleaned, thereby preventing the ashes from accumulating in the combustion chamber, further ensuring the space for storing biomass in the combustion chamber, thereby ensuring the rapid cleaning and practicality of the biomass combustion boiler.

[0039] The high heat absorption rate biomass combustion boiler of the present invention has the following working process:

[0040] During operation, the water inlet pipe 30 and the drain pipe 31 begin to connect to the external heating air, and water will fill the water storage chamber 27 between the water storage frame 26 and the heat dissipation pipe 28. The biomass to be burned is placed in the combustion chamber 12 and ignited. The biomass in the combustion chamber 12 begins to burn at a high speed, and the heat generated at this time will be transferred to the outside through the main box body 11. However, since the heat needs to accumulate and pass through the main box body 11 to heat the water in the water storage chamber 27, the high-temperature gas generated by the combustion will enter the heat dissipation pipe 28 through the guide pipe 29, and then be discharged from the exhaust pipe 39. At this time, the gas will preheat the gas in the water storage chamber 27 in advance, further raising the water temperature in advance, thereby increasing the efficiency of heat penetrating the main box body 11, and reducing the time for heating the water in the water storage chamber 27, thereby ensuring that the heat transfer can be achieved quickly, and since the heat dissipation pipe 28 is all in the water in the water storage chamber 27, the heat discharged from the high-temperature gas will also be fully absorbed.

[0041] When the biomass is burning, the pneumatic cylinder 21 starts to telescope, thereby driving the lifting frame 22, the push plate 40, and the push rod 25 to move up and down along the guide hole 24, thereby creating sufficient gaps between the accumulated burning biomass, further preventing incomplete combustion, and starting the valve 37, thereby driving the oxygen transported by the oxygen pipe 36 to spray from the nozzle 38 into the combustion chamber 12.

[0042] And when sufficient biomass is filled in the combustion chamber 12, biomass can still be added in the storage chamber 34. As the biomass in the combustion chamber 12 burns, the biomass will turn into ashes. At this time, the space in the combustion chamber 12 will be reduced, so that the biomass in the storage chamber 34 will be filled downward under the influence of gravity.

[0043] When use is completed, the push rod 25 begins to reset, and the ashes adhered to the outer cylindrical surface of the push rod 25 will be cleaned by the positioning frame 23. The ashes will be in the combustion chamber 12, and the two groups of threaded motors 14 symmetrically on the left and right begin to start, thereby driving the threaded screw 15 to start rotating, and then driving the threaded slider 16 and the scraper 17 and the sliding frame 18 to start moving forward along the inner wall of the combustion chamber 12, and the ashes adhered to the inner wall of the combustion chamber 12 are quickly cleaned.
