One charge door, feed hopper bottom are provided with discharging opening；The rear and front end of the feeding preheating channel connects the discharging of the hopper respectively
The charging aperture of mouth and burner hearth, the bottom of feeding preheating channel are provided with transport mechanism, and the transport mechanism is including two driving wheels and together
Step is connected in the conveyer belt on two driving wheels；Thermal conductive pipe is provided between the top of feeding preheating channel and roof of the furnace, it is described
One end of thermal conductive pipe connection feeding preheating channel is provided with several heat conduction branch pipes for being uniformly distributed in feeding preheating channel roof；Send
Material preheating channel is provided with least one agitating roller, and agitating roller is provided with rake teeth.
Preferably, the agitating roller is provided with three altogether, and is equably installed on the length direction of feeding preheating channel.
Further, the burner hearth bottom is provided with a pressure fan that air is conveyed toward burner hearth charging aperture.
As described above, biomass solid formed fuel by feeding preheating channel toward during transmitting in burner hearth, pass through
It the stirring of agitating roller, can make pockets of fuel is dispersed to open, increase the contact area of fuel and air, promote the abundant of fuel
Burning, prevents coking phenomenon；Meanwhile the high-temperature gas in burner hearth constantly blows to fuel by thermal conductive pipe, it is carried out
Preheating, can not only dry the moisture remained in inside fuel, moreover it is possible to the charging temperature of fuel is improved, so as to improve heat energy utilization
Rate.

Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further：
Referring to Fig. 1, it is a kind of efficient novel biomass solid molding fuel burner of the present invention, including burner hearth
1st, hopper 3 and feeding preheating channel 2；The inside of burner hearth 1 has a combustion chamber 11, and the inside of combustion chamber 11 is provided with heat exchanger tube
40, one end of heat exchanger tube 40 connects with water inlet pipe 41, and the other end connects heat energy output device (not shown) by delivery line 42, changes
Heat pipe 40 is reciprocal roundabout tubular structure；During work, extraneous cold water is passed through in heat exchanger tube 40 from water inlet pipe 41, by repeatedly past
