Detailed description of the invention
As shown in Figure 1, the biological particles hot-blast stove that the utility model provides, comprises body of heater, pay-off and heater, wherein:
Be provided with fire grate 12 in the burner hearth 10 of described body of heater, described fire grate 12 center is provided with peviform depression, is provided with igniter 13, is also communicated with ajutage 14 bottom described fire grate 12 at described peviform recess;
Described pay-off comprises feed bin (not giving diagram), feeding screw 21, variable-frequency motor 22 and conveying pipeline 23, the arrival end of described feeding screw 21 connects with the discharging opening of described feed bin, the port of export of described feeding screw 21 connects with one end of described conveying pipeline 23, the other end of described conveying pipeline 23 is tilted to down the top being communicated to described peviform depression, described variable-frequency motor 22 is connected with described feeding screw 21 power, carried to the port of export by material in feeding screw 21, then material falls under gravity in peviform depression;
Described heater comprises adjacent and disconnected exhaust gases passes 41 and heat exchanger channels 51, described exhaust gases passes 41 is arranged on below or the inside of described heat exchanger channels 51, its one end is connected with described burner hearth 10, the other end connects smoke exhaust fan 42 to downward-extension and is communicated to outdoor by flue 43 again, one end of described heat exchanger channels 51 is indoor air inlet 52, the other end is heating outlet 53, convection flow fan 54 is also provided with in described heat exchanger channels 51, air is entered from described indoor air inlet 52, absorb the heat in exhaust gases passes 41 in heat exchanger channels 51 after, discharging via described heating outlet 53, to provide warm braw heat to indoor.
When utility model works, biomass fuel in feed bin adds peviform recess to via feeding screw 21 and conveying pipeline 23, then lighted by igniter 13, and the biomass fuel of follow-up interpolation is under the oxygen supply effect of high temperature and ajutage 14, present half vaporized state, Boiling Combustion above peviform depression, can make its sufficient combustion, the discharge of decreasing pollution thing of trying one's best while obtaining the highest thermal efficiency; After the high-temperature flue gas produced transfers heat to the air in heat exchanger channels 51, via outside flue 43 discharge chamber.And room air is under the effect of convection flow fan 54, enter from described indoor air inlet 52, absorb the heat in exhaust gases passes 41 in heat exchanger channels 51 after, discharging via described heating outlet 53, to provide warm braw heat to indoor.
