Detailed description of the invention

As shown in Figure 1, the biomass combustion furnace that the utility model provides, comprises body of heater, pay-off and air-supply arrangement, 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, and be provided with igniter 13 at described peviform recess, described body of heater side is also provided with the crater 11 that can connect with existing boiler; Also be provided with several roller 14 below described body of heater, make it easily mobile and dock with boiler or be separated;

Described pay-off comprises feed bin 20, close wind pay-off 21, variable-frequency motor 22 and conveying pipeline 23, the described wind pay-off 21 that closes has annular space, connect with the discharging opening of described feed bin 20 above this space, below 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, as shown in Figure 2, this space is also separated by the multiple dividing plates 211 arranged radially, described multiple dividing plate 211 drives rotation by described variable-frequency motor 22, the material falling into space from the discharging opening of feed bin 20 is made constantly to be delivered to conveying pipeline 23,
