The controller 4 is mainly used for controlling the start and stop of components, like the controller in the existing automatic control equipment, and can adopt the PLC controller which is widely used in various industries, for example, the PLC controller adopts a programmable memory for storing instructions for executing operations such as logic operation and the like in the controller, and can control various types of machinery or production processes through digital or analog input and output, and the model can be selected by oneself.

Specifically, the feeding anti-backfire system comprises a feeding motor 11 which is arranged on the lower side of an inner cavity of the right furnace body and is electrically connected with the control system, the output end of the feeding motor 11 is connected with a feeding auger 12, the upper side of the feeding auger 12 is communicated with a storage bin 3 which runs through the upper end of the right furnace body, and the discharge end of the feeding auger 12 runs through the left furnace body and is communicated with a suspension blanking port 13. The feeding motor 11 receives an operation instruction of the controller 4, drives the feeding auger 12 to enable stored materials in the storage bin 3 to fall onto the combustion grate 5 through the suspension falling port 13, the suspension falling port 13 and the combustion grate 5 are isolated by adopting space fall, meanwhile, a corresponding fireproof material distributing plate is arranged on the outer side of the suspension falling port 13, and finally tertiary combustion-supporting air of the combustion chamber 14 enters from the falling port, so that the combustion-supporting air is preheated and also cools the falling port.

Specifically, gasification combustion system is including seting up cooking mouth 2 in left furnace body upper end, and the discharge gate intercommunication of cooking mouth 2 has combustion chamber 14, and the bottom of combustion chamber 14 is connected with burning grate 5, and secondary combustion ash box 6 has been arranged to the lower extreme of burning grate 5. The biomass fuel falls into the combustion grate 5 from the suspension falling port 13 and completes gasification combustion on the grate, volatile components are fully combusted in the combustion chamber 14, a big fire cooking function is provided at the cooking port 2, most of the fixed carbon components of the fuel are combusted on the combustion grate 5, and a small amount of fixed carbon falls into the secondary combustion ash box 6 and then continues to complete combustion.

Specifically, the combustion-supporting air distribution system comprises a combustion grate 5, a suspension blanking port 13, a combustion chamber 14 and an air distribution cover plate 15 arranged at an air inlet on the outer side of the combustion chamber 14, and a middle partition plate of the air distribution cover plate 15 divides the air inlet on the outer side of the combustion chamber 14 into an upper part and a lower part. The primary air which is positioned below the combustion grate 5 penetrates through the material layer to provide partial heat for the gasification and volatilization of the fuel on the combustion grate 5 and the combustion of fixed carbon; secondary air enters from an air hole positioned above the combustion grate 5 and is used for burning fixed carbon on the grate and burning volatile matters on the upper part of the combustion chamber 14; the tertiary air directly enters the middle upper part of the combustion chamber 14 from the suspension blanking port 13 for completely combusting volatile matters and cooling the blanking port.

Specifically, the heat exchange application system comprises a combustion chamber 14, a water jacket 1 is sleeved on the periphery of the combustion chamber 14, a front hot air radiation plate 18 is arranged at the position where the combustion chamber 14 is connected with the water jacket 1, a return type flue bin 17 is arranged at one side of a cooking opening 2, the return type flue bin 17 is communicated with a flue 16 arranged on the outer side of the water jacket 1, and an outlet of the flue 16 is communicated with a smoke exhaust opening 10; a water return port 7 and a water outlet 8 which are respectively communicated with the water jacket 1 are arranged on the outer side of the stove body.

Specifically, the cleaning and purifying system comprises a secondary combustion ash box 6 and a heat exchange surface ash removing opening 19 which is communicated and arranged at the bottom side of the rear part of the secondary combustion ash box 6. The carbon fixed part of the fuel is finally burnt out on the secondary combustion ash box 6 and is directly shoveled out and poured out, the smoke and dust carried by a small amount of smoke are collected at the bottom under the inertia effect of a rear flue, and the dust cleaning treatment can be carried out at regular time by opening 19 heat exchange surface dust cleaning ports.

The working principle is as follows: when the biomass briquette fuel is started, the feeding motor 11 receives an operation instruction of the controller 4 and then drives the feeding auger 12 to drop the stored material in the storage bin 3 onto the combustion grate 5 through the suspension discharge port 13. When ignition and ignition are carried out, feeding is stopped, and after ignition is successful, the feeding motor 11 starts to intermittently operate and feed according to the operation instruction of the controller 4. After falling on the combustion grate 5, the biomass briquette fuel is heated by the fixed carbon accumulated on the combustion grate 5 and then is combined with primary air entering from the bottom to complete preheating, volatilization and gasification, the fuel is volatilized and analyzed and then is converted into the fixed carbon to be continuously combusted and released heat on the combustion grate 5, and then burnout ash and a small amount of small unburnt ash fall into the secondary combustion ash box 6 under the action of smashing and falling of new materials to complete the burnout and heat release process. After the combustion grate 5 is volatilized and analyzed, the secondary fan entering from the upper part of the combustion grate 5 is combined to finish full combustion under the combined action of tertiary air entering from the hanging falling port 13, and flame and high-temperature smoke are collected at the lower part of the cooking port 2 to provide a cooking function. The high-temperature flue gas passes through the cooking opening 2 and sequentially passes through the return type flue bin 17 and the flue 16 to exchange heat with the heat exchange surface of the water jacket 1. Meanwhile, the particles in the flue gas are deposited in the circulating flue due to the gravity inertia effect. The final relatively clean flue gas is discharged via the exhaust port 10. The outer side of the smoke outlet 10 is connected with a chimney, and the tail end of the smoke outlet can be connected with a pumping device. Heated circulating hot water enters the furnace body water jacket through the water return port 7, is finally discharged from the water outlet 8 after a series of reverse heat exchange in the water jacket 1, and the furnace water jacket 1 is provided with a safety valve port 9 which is mainly used for connecting an explosion-proof valve to ensure the use safety. The combustion-supporting air of the stove adopts three-level air distribution, and primary air enters from the lower part of the combustion grate 5 and penetrates through the material layer, and is mainly used for gasifying and volatilizing granular fuel on the combustion grate 5 and burning out fixed carbon; secondary air enters the hearth from the upper part of the combustion grate 5 and is mainly used for fully combusting volatile matters in the hearth and promoting the accumulated fixed carbon on the grate to be burnt out; the tertiary air is primarily drawn from the drop opening 13 and is preferably used to cool the drop opening to prevent fire and then to promote the burn-off of volatiles in the combustion chamber 14. The secondary ash burning box 6 is mainly used for storing fuel burnout ash and completing complete burning out of residual little unburned fixed carbon. The deposited ash in the secondary combustion ash box 6 can be periodically pumped out and directly poured out; the 19 heat exchange surface ash cleaning port is mainly used for cleaning buffer accumulated ash in a flue regularly and can be directly taken out during cleaning.
