Abstract
The utility model discloses a kind of biomass combustion boiler, comprising: fire box, is arranged on the upper drum in fire box, lower drum, material blanking tube, warm-air pipe, fire grate and air compartment; Connected by convection current endothermic tube between described upper drum, lower drum; It is characterized in that: on material blanking tube, be connected with high-pressure air tube, between the outlet of material blanking tube and fire grate, there is difference in height.During real work, fuel lighter in biomass fuel to be combusted is directly suspended in the aerial burning of fire box under the effect of pressure-air, and heavier fuel leaves and burns on fire grate; Make full use of biomass fuel easily (loose in transportation, disconnected) cause the phenomenon of powder, adopt a kind of anti-burning mode of aerial burning, biomass boiler 100% can be allowed to burn, then boiler heating is allowed to boost fast, what can meet user uses vapour demand, and the situation especially larger by vapour demand fluctuation is obvious especially, thus reduces energy waste.
Description
Technical field
The utility model relates to boiler, particularly relates to a kind of living beings that utilize as the boiler of fuel.
Background technology
Biomass combustion boiler, as the term suggests the boiler being exactly using biomass energy as fuel, its combustion apparatus adopted is reciprocating fire grate.
Concrete combustion process is: fuel sends into furnace top bin by conveyer, then sends into burner hearth by screw(-type) feeder, is evenly scattered on fire grate.When fuel is sent into burner hearth by screw(-type) feeder, due to high-temperature flue gas and a wind action progressively preheating, dry, catch fire, burn, separate out a large amount of volatile matter in this process, burning acutely.After the high-temperature flue gas produced washes away the main heating surface of boiler, enter heated surface at the end of boiler economizer and air preheater, then enter deduster, enter air finally by chimney.Move to back of furnace row in the fuel limit of not gasifying, until after-flame, finally remaining a small amount of lime-ash fall into fire grate below except cinder notch.
At present, the efficiency of this traditional type biomass combustion boiler is general all about 80%, for making the more abundant of burning, usually adopting and strengthening boiler model (size).According to market survey statistics, the boiler efficiency of maximum model is also about 88%.
Utility model content
The biomass combustion boiler that the purpose of this utility model is to provide a kind of, increasing temperature and pressure fast, sufficient combustion, efficiency are high.
For reaching above object, the utility model adopts following technical scheme.
A kind of biomass combustion boiler, is characterized in that, comprising: fire box, be arranged on the upper drum in fire box, lower drum, material blanking tube, warm-air pipe, fire grate and air compartment; Connected by convection current endothermic tube between described upper drum, lower drum; It is characterized in that: on material blanking tube, be connected with high-pressure air tube, between the outlet of material blanking tube and fire grate, there is difference in height.
Further illustrating as such scheme, described high-pressure air tube air outlet and material blanking tube export and connect together, and high-pressure air tube air outlet is positioned at material blanking tube outlet downside.
Further illustrating as such scheme, the difference in height between described material blanking tube outlet and fire grate is not less than 50cm.
Further illustrating as such scheme, described upper drum is arranged on fire box top.
Further illustrating as such scheme, described lower drum to be positioned at above material blanking tube and to be positioned at below warm-air pipe.
Further illustrating as such scheme, described material blanking tube and warm-air pipe are positioned at the not homonymy of fire box.
Further illustrating as such scheme, described fire grate is arranged on the bottom of fire box, and described air compartment is positioned at the below of fire grate and is communicated with fire box.
Compared with prior art, the beneficial effects of the utility model are: fuel lighter in biomass fuel to be combusted is directly suspended in the aerial burning of fire box under the effect of pressure-air, and heavier fuel leaves and burns on fire grate; Make full use of biomass fuel easily (loose in transportation, disconnected) cause the phenomenon of powder, adopt a kind of anti-burning mode of aerial burning, biomass boiler 100% can be allowed to burn, then boiler heating is allowed to boost fast, what can meet user uses vapour demand, and the situation especially larger by vapour demand fluctuation is obvious especially, thus reduces energy waste.

Detailed description of the invention
Understand essence of the present utility model better for convenience of those skilled in the art, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, a kind of biomass combustion boiler, comprise: fire box 1, be arranged on the upper drum 2 in fire box 1, lower drum 3, material blanking tube 4, warm-air pipe 5, fire grate 6 and air compartment 7, connected by convection current endothermic tube 8 between upper drum 2, lower drum 3.
Wherein, described upper drum 2 is arranged on the top of fire box 1, and described lower drum 3 to be positioned at above material blanking tube 4 and to be positioned at below warm-air pipe 5, and material blanking tube 4 and warm-air pipe 5 are positioned at the not homonymy of fire box 1.Described fire grate 6 is arranged on the bottom of fire box 1, and described air compartment 7 is positioned at the below of fire grate 6 and is communicated with fire box 1.
Between the outlet and fire grate 6 of material blanking tube 4, there is difference in height, material blanking tube 4 is connected with high-pressure air tube 9.The air outlet of described high-pressure air tube 9 and the outlet of material blanking tube 4 connect together, and the air outlet of high-pressure air tube 9 is positioned on the downside of the outlet of material blanking tube 4.In the present embodiment, the pressure of preferred pressure-air is 1.5 standard atmospheric pressures, and in other embodiments, the pressure of described pressure-air, more than 1.2 standard atmospheric pressures, is not limited to the present embodiment.
Like this, during real work, what utilize pressure-air carries biomass fuel to be combusted.Fuel lighter in biomass fuel to be combusted is directly suspended in the aerial burning of fire box 1 under the effect of pressure-air, heavier fuel leaves in fire grate combustion zone, the heat major part that burning produces acts directly on convection current endothermic tube, quick heat exchange.The tail gas that burning produces is discharged by warm-air pipe.
Compared with prior art, the present embodiment utilizes biomass fuel easily (loose in transportation, disconnected) cause the phenomenon of powder, adopt a kind of anti-burning mode of aerial burning, biomass boiler 100% can be allowed to burn, and then allow boiler heating boost fast, what can meet user uses vapour demand, situation especially larger by vapour demand fluctuation is obvious especially, thus reduces energy waste.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, such as material blanking tube and warm-air pipe are positioned at the same side of fire box, such as the difference in height between material blanking tube outlet and fire grate are limited to more than 50cm etc. again.It should be noted that these improve and modify all to drop within claims of the present utility model.
