The biomass fuels boiler includes a hearth, a grate is arranged at the bottom of the hearth, and an air compartment is arranged below the grate. The lower part of the front side of the hearth is provided with a furnace mouth, the front side of the furnace mouth is provided with a feeding chamber. One end of the feeding chamber is connected to the furnace mouth, the other end of the feeding chamber is provided with a pusher. A hopper is arranged at the top part of the feeding chamber in front of the pusher. The utility model is characterized in that the grate is a crossbeam type chain grate. Such a biomass fuels boiler can greatly improve combustion efficiency.
Description
Technical field
The utility model relates to a kind of boiler.Specifically, be the biomass fuel boiler that acts as a fuel with agricultural crop straw, tree branches, agriculture and forestry organic waste material and domestic waste.
Background technology
Know all that in the boiler for producing industry at present, the biomass fuel boiler that acts as a fuel with agricultural crop straw, tree branches, agriculture and forestry organic waste material and domestic waste all is a conventional boiler.This conventional boiler comprises burner hearth, and burner hearth bottom has fire grate, and side lower part has fire door before the burner hearth, and there is the feeder compartment fire door front side.Feeder compartment's one end links to each other with fire door, and the other end has pusher.Hopper is arranged at the top, feeder compartment in pusher the place ahead.Fire grate wherein mainly contains three kinds of water-cooled vibrating-grate stoker, reciprocating fire grate and combined type fire grates, and the shortcoming of these three kinds of fire grates is that burning is insufficient, and efficiency of combustion is low.In addition, the pusher of above-mentioned boiler all is spiral pusher, and the material of spiral pusher dead ahead and its both sides is very inhomogeneous, and like this, the material that enters both sides in the burner hearth burnouts easily, and the material in the middle of entering in the burner hearth just is difficult to burnout.Therefore, adopt the boiler of spiral pusher, can further reduce the efficiency of combustion of material.Moreover above-mentioned boiler only is provided with air compartment below fire grate, makes the material that enters in the burner hearth be difficult to stir back and forth, so also can influence the efficiency of combustion of material.
The utility model content
The utility model relates to a kind of biomass fuel boiler.Adopt this biomass fuel boiler, can improve efficiency of combustion greatly.
For addressing the above problem, take following technical scheme:
Biomass fuel boiler of the present utility model comprises burner hearth, and burner hearth bottom has fire grate, and there is air compartment the fire grate below.Side lower part has fire door before the burner hearth, and there is the feeder compartment fire door front side.Feeder compartment's one end links to each other with fire door, and the other end has pusher.Hopper is arranged at the top, feeder compartment in pusher the place ahead.Its design feature is that described fire grate is a crossbeam type chain-grate.
Wherein, described pusher contains hydraulic cylinder, and hydraulic cylinder is fixed on the outer end, feeder compartment, and its piston rod stretches in the feeder compartment and is connected to push pedal.The plate face of described push pedal is vertical with piston rod.When the piston rod indentation, push pedal is in the outside of hopper.
Before and after crossbeam type chain-grate, on the hearth wall of side the secondary wind inlet is arranged all.
Described crossbeam type chain-grate waits to expect that by cross beam type traveling-grate stoker and cross beam type combustion chain furnace row form, wherein, cross beam type waits to expect that traveling-grate stoker and cross beam type combustion chain furnace row are in the bottom of the fire door outside and burner hearth respectively, and the two is gap-like and is close together.
Take such scheme, have the following advantages:
By such scheme as can be seen, because described fire grate is a crossbeam type chain-grate.Compare with combined type fire grate with traditional water-cooled vibrating-grate stoker, reciprocating fire grate, can improve the efficiency of combustion of material.Because described pusher contains hydraulic cylinder, and hydraulic cylinder is fixed on the outer end, feeder compartment, its piston rod stretches in the feeder compartment and is connected to push pedal again.Compare with spiral pusher, can make the material that enters in the burner hearth even, make the material that enters in the burner hearth be easy to burnout, thereby improved the efficiency of combustion of material.
In addition owing to be on the basis of air compartment at a wind inlet below original fire grate, before and after crossbeam type chain-grate, all be provided with the secondary wind inlet on the hearth wall of side again, make the material that enters in the burner hearth to stir back and forth, so also can further improve the efficiency of combustion of material.
Description of drawings
Fig. 1 is a biomass fuel boiler structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, biomass fuel boiler of the present utility model comprises burner hearth 6, burner hearth 6 bottoms are provided with fire grate, this fire grate is a crossbeam type chain-grate, it waits to expect that by cross beam type traveling-grate stoker 2 and cross beam type combustion chain furnace row 3 form, wherein, cross beam type waits to expect that traveling-grate stoker 2 and cross beam type combustion chain furnace row 3 are in the bottom of the fire door outside and burner hearth 6 respectively, and the two is gap-like and is close together.The fire grate below is provided with the i.e. wind inlet 4 of air compartment, is provided with secondary wind inlet 5 on burner hearth 6 walls of side before and after the fire grate.
Burner hearth 6 rear sides are provided with cooling chamber 7, are provided with high temperature superheater 8 in the cooling chamber 7.Cooling chamber 7 rear sides are provided with flue 9, and low temperature superheater 10 is installed in the flue 9.Flue 9 rear sides are provided with province coal chamber 11, economize in the coal chamber 11 and are provided with economizer 12.Cooling chamber 7 all communicates with 9 of flues, flue 9 and 11 of province coal chambers.
Be processed with fire door on the furnace wall of side lower part before the burner hearth 6, the fire door front side is provided with feeder compartment 1.Feeder compartment's 1 one ends link to each other with fire door, and the other end is provided with pusher.1 top, feeder compartment in pusher the place ahead is equipped with hopper 16.Described pusher contains hydraulic cylinder 15, and hydraulic cylinder 15 is fixed on 1 outer end, feeder compartment, and its piston rod 14 stretches in the feeder compartment 1 and is connected to push pedal 13, and the plate face of described push pedal 13 is vertical with piston rod 14.When piston rod 14 indentations, push pedal 13 is in the outside of hopper 1.
During work, material enters feeder compartment 1 through hopper 16, driving push pedals 13 by the piston rod 14 of hydraulic cylinder 15 pushes the material in the feeder compartment 1 on the fire grate in the burner hearth 6 and burns, a wind inlet 4 by fire grate below is that material on 5 pairs of fire grates of secondary wind inlet on burner hearth 6 walls of side before and after air compartment and the fire grate stirs again, makes the material on the fire grate be able to abundant burning.
