Description

Use biomass boiler more
Technical field
The utility model relates to a kind of multipurpose boiler, relates in particular to the boiler that a kind of thermal source is living beings.
Background technology
Usually thermal source is the horizontal chained fire grate of the many employings of boiler of living beings, and the traditional air-supply combustion system of this boiler is the air-supply of fire grate bottom, and this has just caused following several problems:
1. biomass fuel fugitive constituent height, adopt the combustion system of fire grate bottom air-supply easily to cause ignition zone fugitive constituent incomplete combustion, boiler is smoldered even the over-emitting black exhaust phenomenon, adopts any deduster all can't eliminate, soot emissions are seriously defective, reduced efficiency of combustion simultaneously significantly.
2. biomass fuel density is little, easily flies upward during burning.Adopt the combustion system of fire grate bottom air-supply, can particularly form a lot of burners and fuel is piled up in the primary zone, cause grate inhomogeneous and leak out in a large number and the slag incomplete combustion, reduce efficiency of combustion significantly at fire grate.
3. the biomass fuel ash fusion point is less than 900 ℃, easily coking.Adopt the air-supply of fire grate bottom combustion system can fire grate particularly the high temperature that produces greater than 1200 ℃ of primary zone cause slagging scorification phenomenon on the fire grate, serious slagging scorification meeting causes the fire grate mechanical breakdown and stops up flue, influences boiler and normally moves.
The utility model content
Technical problem to be solved in the utility model is the drawback that exists when overcoming conventional chains furnace grate biological substance for combustion, and a kind of multipurpose boiler of burning living beings preferably is provided.
Adopt following technical scheme for solving the problems of the technologies described above: a kind of biomass boilers of using more, comprise burner hearth, lower furnace portion is provided with traveling-grate stoker, both sides are respectively face arch and rear arch before and after the burner hearth, the face arch front side is provided with coal bunker and coal gate, be provided with wind apparatus in the traveling-grate stoker one time, described face arch and rear arch place are furnished with overfire air device respectively.
Described overfire air device is made up of an air main and some wind pipe arrangements, is positioned at the face arch and the rear arch place at furnace outlet place.
Described wind pipe arrangement is perpendicular to the air main setting, and its quantity is at least two.
The utility model increases overfire air device respectively at forward and backward arch place; purpose is: strengthen flow perturbation between the arch of burner hearth front and back; strengthen fuel and Air mixing; prolong the time of staying of fuel at burner hearth; make that furnace cavity burning is more violent, burning is more abundant, reduce the gas incomplete combustion loss, prevent the boiler over-emitting black exhaust; improve boiler combustion efficiency, be beneficial to environmental protection.After adopting overfire air device, traveling-grate stoker bottom air output reduces, and moves in the anoxycausis mode on the traveling-grate stoker, and the wind speed of fire grate and temperature all are in controlled fully low-level.The utlity model has compact conformation, volume is little, cost is low, floor space is little and advantage such as cleaning, environmental protection, efficient energy-saving.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram.
Fig. 2 is the utility model overfire air device structural representation.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of biomass boiler of using more, comprise burner hearth 4, burner hearth 4 bottoms are provided with traveling-grate stoker 3, both sides, burner hearth 1 front and back are respectively face arch 5 and rear arch 6, face arch 5 front sides are provided with coal bunker 1 and coal gate 2, are provided with wind apparatus 8 in the traveling-grate stoker 3 one time, and described face arch 5 and rear arch 6 places are furnished with overfire air device 7 respectively.Overfire air device 7 is made up of an air main 9 and 7 wind pipe arrangements 10, and wind pipe arrangement 10 is provided with perpendicular to air main 9, and overfire air device 7 is positioned at the face arch 5 and rear arch 6 places in burner hearth 4 exits.
Described wind pipe arrangement 10 quantity are at least two, can be 3,4,5,8,10 or more.
Described wind pipe arrangement 10 also can tilt to be fixed on the air main 9.
Biomass fuel is through coal bunker 1, fall on the traveling-grate stoker 3 by coal gate 2, wind apparatus 8 is set in the traveling-grate stoker 3 one time, a certain proportion of wind enters traveling-grate stoker 3 bottoms by air blast in the air blast mode, after regulating blast and air quantity, each air compartment air register sends into each air compartment, under a wind effect, biomass fuel carries out low temperature, anoxycausis on traveling-grate stoker top, produces unburnt gas.Face arch 5 and rear arch 6 in the exit are provided with overfire air device, and secondary wind is sent into the air main 9 of overfire air device 7 after blower fan is regulated blast and air quantity by air register, send into burner hearth 4 middle parts by distributing pipe 10.The secondary wind that the overfire air device 7 of face arch 5 and rear arch 6 produces produces flow perturbation at burner hearth 4 middle parts, strengthen biomass fuel and Air mixing, prolong the time of staying of biomass fuel at burner hearth, simultaneously, biomass fuel carries out the anoxycausis generation on traveling-grate stoker top unburnt gas fully mixes with air, make that furnace cavity burning is more violent, burning is more abundant, reduce the fugitive constituent heat loss due to incomplete combustion, improve boiler combustion efficiency.
The utility model is many not only to burn living beings with biomass boiler, and coal can well burn equally.When burning coal, secondary wind is turned off, coal gate also lowers, and makes the coal seam keep certain thickness to send into burner hearth, and this moment is wind for once, makes coal be in optimal combustion state by blast and the air quantity of regulating a wind.
