The rotary shaft is driven by driving motor, is connected with chain or belt and gear drive；
Retarder is housed on the driving motor.
Exchange pipe is horizontal or tilting is connect with water jacket.
The course of work：
Blanking：Biomass granule fuel falls to blanking intracavitary by inclined plate, and rotation is pushed under the action of worm propeller
In fire grate, stopped by striker plate, can only cannot be returned to the inside propellant of rotary fire grate.
Burning：By the filling of granular bio-fuel in holding bin, then start driving motor, drives rotary fire grate rotation
Turn, while rotating, granular fuel is pushed ahead by worm propeller and material toggling tooth, is lighted a fire simultaneously, particular biological
Matter fuel burns therewith, first burns from extra-granular, and the ashes after outer layer burning are drained into the lower part of combustion chamber from ash leakage hole, fixed
Phase opens the discharge of deashing bucket, and with the successively burning of granular fuel, last after-flame forms ashes, is discharged by ash leakage hole, and
Afterwards, fuel gradually promotes under the action of material toggling tooth, and combustion process, the flame of biomass fuel combustion is maintained to be drained into heat exchanger
It is interior, and water jacket and tube heat exchange is exchanged, the water in heating heat exchanger is discharged, heat supply makes by water inlet tube of intaking by outlet pipe
With.
Technical principle：
Biomass granule fuel is added directly into the cylinder of rotary fire grate, is pushed ahead in the effect of material toggling tooth, with particle
Surface is burnt, and the sufficient outer layer skin that burns is fallen, and continues to keep graininess without the complete fuel that burns, with after afterflame
It burns until burning totally, completes combustion process.
