This heat supply method has the characteristics of high efficiency, environmental protection and sustainability, and can effectively integrate the traditional power generation capacity and the environmental protection characteristics of renewable energy. In the context of the increasing shortage of traditional energy and the gradual emergence of environmental pollution problems, promoting the adjustment of the energy structure and the development of clean energy has become a global consensus. Cogeneration is a system based on the concept of cascade utilization of energy, integrating the power generation and heat supply processes. The core of this system lies in improving the utilization efficiency of fuel and reducing energy waste. The combined operation of a thermal power plant and a biomass boiler can achieve the optimal combination of fossil energy and renewable energy, further reducing carbon emissions and environmental pollution.

The outer right end of the rotating shaft 8 is fixedly connected to the inner wall of one of the gears 10, and the two gears 10 are meshed with each other. Due to the meshing relationship of the two gears 10, when the rotating shaft 8 drives one of the gears 10 to rotate, it will drive the other gear 10 to rotate.

[0045] Refer to Figure 3 , Figure 5 and Figure 6, a support leg 24 is fixedly connected to the left end of the top side of the bottom plate 1, a support plate 25 is fixedly connected to the top side of the support leg 24, the top of the support plate 25 is fixedly connected to the outside of the U-shaped tube 23, and a connection tube 26 is fixedly connected to the front end of the U-shaped tube 23. By providing a supporting force to the U-shaped tube 23, the connection tube 26 is prevented from tilting under gravity. A clamping component for clamping subsequent components is fixedly connected to the outside of the connection tube 26. The clamping component includes a fixing ring 27, and the inside of the fixing ring 27 is fixedly connected to the outside of the connection tube 26 to provide a supporting force for the fixing ring 27. Through the cavity formed inside the connection tube 26, the limiting ball 36 can move inside the connection tube 26 and will not fall off. A spring 28 is fixedly connected to the front end of the fixing ring 27, and a sliding ring 29 is fixedly connected to the front end of the spring 28. By fixing both ends of the spring 28, the spring 28 can be evenly stressed. A limiting ring 30 is fixedly connected to the inner wall of the connection tube 26 for resisting subsequent components. A sliding cylinder 31 is slidably connected to the inner wall of the connection tube 26. Due to the restriction of the connection tube 26 on the sliding cylinder 31, the sliding cylinder 31 can slide back and forth;

[0046] A connection tube 32 is fixedly connected to the front side of the sliding cylinder 31 to provide a supporting force for the connection tube 32. A plurality of springs 33 are fixedly connected to the inner wall of the rear end of the sliding cylinder 31, and a sealing ring 34 is fixedly connected to the rear ends of the plurality of springs 33. By fixing both ends of the springs 33, the springs 33 can be evenly stressed. The sealing ring 34 is in contact with the front side of the limiting ring 30. By fitting the sealing ring 34 with the limiting ring 30, the connection tube 32 can be sealed with the sliding ring 29. Arc-shaped openings 35 are formed on both the left and right sides of the sliding cylinder 31, and limiting balls 36 are movably connected to both the left and right ends of the connection tube 26. By restricting the limiting balls 36 through the formed arc-shaped openings 35, the limiting balls 36 can be clamped on the sides of the sliding cylinder 31. The left and right sides of the inner wall of the sliding ring 29 are respectively in contact with the outside of the two limiting balls 36.

[0047] Working principle: First, pour biomass into the interior of the limit frame 5 and let it fall onto the crushing roller 11. Then, drive the rotating shaft 8 to rotate by the driving motor 7, thereby driving one of the gears 10 to rotate. Then, one of the gears 10 will drive another meshing gear 10 to rotate, enabling the other gear 10 to drive the driven shaft 9 to rotate. At this time, the rotating shaft 8 and the driven shaft 9 will respectively drive a crushing roller 11 to rotate in opposite directions to crush the biomass. Then, the crushed biomass will fall onto the triangular frame 6 and slide onto the triangular plate 14 by the inclined gravity. At this time, the crushed biomass will accumulate from the left side to the right side of the triangular plate 14. Then, burn the crushed biomass. The crushed biomass can fully contact with the oxygen in the air for combustion, thereby improving the thermal efficiency. At the same time, water is introduced into the interior of the water storage tank 15 through the water inlet pipe 16, and the water can be higher than the heat receiving plate 13. At this time, the heat generated inside the biomass boiler body 2 will be transferred to the water inside the water inlet pipe 16 through the heat receiving plate 13. The designed water inlet pipe 16 boils to generate hot gas for heating. At this time, the rotating shaft 8 and the driven shaft 9 will also drive a connecting shaft 17 to slide respectively, thereby driving the cylinder 18 to rotate, and then driving a plurality of guide vanes 19 to rotate respectively. Through the rotation of the plurality of guide vanes 19, it can divert the hot steam inside the water storage tank 15 into the interior of the furnace body outlet pipe 21, thereby improving the efficiency of hot steam transportation. At the same time, the rotating shaft 8 and the driven shaft 9 will also drive the cleaning plate 12 to rotate and clean the heat receiving plate 13, removing the gas particles generated by combustion on the right side of the heat receiving plate 13, avoiding the formation of a pot due to dust accumulation and affecting the transfer of thermal efficiency, and then further improving the efficiency of heat transfer;

[0048] Then, the hot steam generated inside the water storage tank 15 will be transported to the inside of the U-shaped pipe 23 through the furnace body air outlet pipe 21 to the left, and the waste heat generated by the thermal power plant will be transported to the inside of the U-shaped pipe 23 through the thermal power plant air outlet pipe 22. At this time, the hot air will be transported through the connecting pipe 32. At the same time, by holding the sliding ring 29 and squeezing the first spring 28, the first spring 28 can store elastic potential energy. After the sliding ring 29 no longer wraps the limiting ball 36, the limiting ball 36 will no longer be subjected to the force resisted by the sliding ring 29. At this time, the connecting pipe 32 can be held and removed, thereby driving the sliding cylinder 31 to slide and pushing the limiting ball 36 to slide outwards, so that the limiting ball 36 no longer engages with the arc-shaped opening 35, so that the connecting pipe 32 can be quickly removed. On the contrary, driving the sliding cylinder 31 to slide inside the connecting pipe 26 by the connecting pipe 32 and contacting the limiting ring 30. At this time, the limiting ring 30 will resist the sealing ring 34, so that the sealing ring 34 is stressed and thus squeezes the sealing ring 34, so that the sealing ring 34 can store elastic potential energy, and then gives the sealing ring 34 a force in the opposite direction to fit with the limiting ring 30, thereby improving the sealing performance between the connecting pipe 32 and the connecting pipe 26, so as to avoid air leakage; at the same time, after the sliding cylinder 31 slides to the bottom, release the force on the sliding ring 29, so that the first spring 28 can reset and push the sliding ring 29 to reset and resist the limiting ball 36 to slide and engage inside the sliding cylinder 31, so that the docking of the sliding cylinder 31 can be quickly completed, and then the maintenance efficiency can be improved.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
