Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] The utility model provides a combustion chamber for burning high-moisture wood chips, such as Figure 1-Figure 3As shown, it includes a furnace body 1, a furnace chamber 3 is provided at the lower part of the furnace body 1, a hopper 4 is installed at one end of the furnace body 1, a dust collecting bin 12 is provided at the upper part of the furnace body 1, a smoke folding wall 121 is installed at the upper part of the dust collecting bin 12, a chain grate 2 is installed at the bottom of the furnace body 1, a smoke outlet 124 is provided at one end of the furnace body 1, a front arch refractory layer 32 is installed at the front of the furnace chamber 3, a rear arch refractory layer 36 is installed at the top of the furnace chamber 3, a side wall refractory layer 34 is installed on the side of the furnace chamber 3, a side wall insulation layer 35 is installed on the outer wall of the side wall refractory layer 34, and a rear side refractory layer 37 is installed at the rear of the furnace chamber 3. The design of the furnace chamber 3 at the lower part of the furnace body 1, combined with the hopper 4 installed at the front end, facilitates the continuous supply and combustion of wood chips; while the dust collecting bin 12 at the upper part of the furnace body 1 and the smoke folding wall 121 at the upper part of the furnace body 1 effectively capture and guide smoke, reduce direct smoke emissions, and improve the environmental performance of the combustion chamber.
[0022] The chain grate 2 installed at the bottom not only ensures uniform combustion of the wood chips but also improves combustion efficiency. Furthermore, the front arch refractory layer 32 at the front of the hearth 3, the rear arch refractory layer 36 at the top, the side wall refractory layers 34, and the rear side refractory layer 37 at the rear together form a robust refractory system that can withstand high-temperature combustion environments, protect the furnace structure from damage, and extend the service life of the combustion chamber.
[0023] In this embodiment, the outer wall of the furnace body 1 is provided with a steel frame outer shell 11 to ensure external protection.
[0024] Specifically, an air regulating port 122 is provided on one side of the dust collecting bin 12 for regulating the air intake volume.
[0025] Furthermore, a furnace door 31 is installed on one side outer wall of the furnace 3 to facilitate the adjustment of the internal fuel turnover and assist in sufficient combustion.
[0026] Furthermore, the outer wall of the front arch fireproof layer 32 is installed with a front arch insulation layer 33, the outer wall of the side wall fireproof layer 34 is installed with a side wall insulation layer 35, and the outer wall of the rear side fireproof layer 37 is installed with a rear wall insulation layer 38, which has a good insulation effect.
[0027] Furthermore, a top fire-resistant layer 39 is installed on the top of the dust collecting bin 12 to improve the fire-resistant effect of the top.
[0028] Furthermore, a cleaning port 123 is provided on one side of the lower portion of the dust collecting bin 12 for cleaning impurities in the dust collecting bin 12 .
[0029] Furthermore, a blast port 13 is provided at the bottom of the furnace body 1 near one end of the chain grate 2 for performing a blast operation on the chain grate 2 .
[0030] During use, the high-moisture wood chip combustion chamber of this utility model first continuously feeds high-moisture wood chips into the furnace 3 within the furnace body 1 via the hopper 4. The design of the furnace 3, combined with the front-mounted hopper 4, ensures smooth entry of the wood chips and stable combustion. During the combustion process, the bottom-mounted chain grate 2 plays a key role, not only carrying the wood chips but also ensuring uniform chip rotation through chain transmission, thereby ensuring sufficient combustion and improving combustion efficiency.
[0031] At the same time, the front, top, sides, and rear of the furnace 3 are respectively equipped with a front arch refractory layer 32, a rear arch refractory layer 36, a side wall refractory layer 34, and a rear side refractory layer 37. These refractory layers together form a robust refractory system that can withstand high-temperature combustion environments, protect the furnace structure from damage, and effectively extend the service life of the combustion chamber. The front arch insulation layer 33, side wall insulation layer 35, and rear wall insulation layer 38 installed on the outer walls of the refractory layer further reduce heat loss and improve the thermal efficiency of the combustion chamber.
[0032] The smoke generated during the combustion process is captured and collected by the dust collection bin 12 located above the furnace body 1. The smoke deflection wall 121 above the dust collection bin 12 effectively guides the flow of smoke, reducing direct smoke emissions and thus improving the environmental performance of the combustion chamber. Furthermore, an air adjustment port 122 is provided on one side of the dust collection bin 12 to adjust the air intake according to combustion needs to optimize combustion.
[0033] In addition, a furnace door 31 is installed on one side of the outer wall of the furnace 3, allowing operators to enter the furnace to stir and adjust the fuel to promote the full combustion of the wood chips. A cleaning port 123 is provided on one side of the lower portion of the dust collection bin 12 to facilitate the regular cleaning of impurities inside the dust collection bin, maintaining a clean and efficient operation of the combustion chamber.
[0034] Finally, a blast port 13 is provided at the bottom of the furnace body 1 near one end of the chain grate 2 for blowing air to the chain grate, thereby further promoting the full combustion of the wood chips and the effective emission of smoke.
[0035] In summary, the combustion chamber for burning high-moisture wood chips of the present invention achieves efficient combustion and smoke control of high-moisture wood chips through exquisite structural design and reasonable working principle, demonstrating excellent technical effects and environmental value.
