Technical field
The utility model relates to a kind of boiler of biomass burning, particularly a kind of horizontal fast-assembling traveling-grate stoker biomass boiler.
Background technology
At present, horizontal fast-assembling chain grate boiler structurally all is to adopt air zoning in chain fire-gate both sides, it is combustion-supporting promptly only to use air supply device to carry out air feed, but the gas componant of emitting at each section of the fuel bed on the traveling-grate stoker still has nothing in common with each other like this, chain fire-gate rear and front end exists excess air, and at chain fire-gate middle part, then because fuel bed (coal seam) exists the reducing zone, can produce fuel gas, a part that adds the upper chain-grate stoker front portion has little time the volatile ingredient of after-flame, makes in the gas componant on grate top and exists many fuel gas.In order to allow these fuel gas, ickings and burner hearth (combustion chamber) excess air mix well, make it in the burner hearth internal combustion, and the required heat that catches fire of these fuel mainly relies on the radiation of burner hearth high-temperature flue gas and chimney arch, at present, horizontal fast-assembling chain grate boiler is poor for solving ignition condition, just adopts high and short face arch to cooperate with rear arch, causes an aditus laryngis that impels air-flow to mix, but this scheme just plays the effect of igniting of a part, can not thoroughly improve ignition condition.Effect is poorer during particularly this horizontal fast-assembling chain grate boiler firing biomass fuel, because biomass fuel can produce more fuel gas at this burning condition, these fuel gas are difficult to burning basically under this condition, cause fuel availability very low.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of horizontal fast-assembling traveling-grate stoker biomass boiler is provided, and it can firing biomass fuel, firing biomass fuel efficient height.
The technical solution of the utility model is: a kind of horizontal fast-assembling traveling-grate stoker biomass boiler, and it comprises boiler body and flue gas system; Boiler body comprises furnace wall, drum, traveling-grate stoker, face arch, rear arch, air supply device and secondary air supply device; Drum is installed in top, furnace wall, and the furnace wall comprises sidewall, antetheca and rear wall, forms preceding combustion chamber between face arch and the traveling-grate stoker, forms after-burner between rear arch and the traveling-grate stoker; The secondary air supply device comprises secondary air feed pipe and secondary air blast, and the secondary air supply device can be dried in the combustion chamber forward by secondary air feed pipe and secondary air blast.
The further technical scheme of the utility model is: described secondary air feed pipe comprises that secondary main feed pipe and secondary prop up the air feed pipe, the secondary main feed pipe is located in the furnace wall of preceding combustion chamber and after-burner side, its air intake is connected with the secondary air blast, the secondary main feed pipe is positioned on the tube wall of part of antetheca and has air outlet, secondary props up more than the air feed Guan Weiyi root, the end that every secondary props up the air feed pipe is connected air outlet place of secondary main feed pipe, and preceding combustion chamber is led in the outlet of its other end.
The utility model further technical scheme is: also be provided with heat-insulation layer outside described drum and the furnace wall.
The utility model compared with prior art has following characteristics:
1, the correction of doing on the basis of original horizontal fast-assembling chain grate boiler seldom just can firing biomass fuel, has solved the problem that horizontal in the past fast-assembling chain grate boiler is difficult to firing biomass fuel;
2, the secondary air supply device can improve the ignition condition of fuel gas; Cause the flue gas vortex, prolong the stroke of flying dust in stove; Make the stove internal combustion more stable; Make fuel economy higher;
3, can reduce discharging:, outwards discharge so reduced these compositions, more environmental protection because compositions such as fuel gas, ickings obtain more abundant burning.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.

The specific embodiment
Embodiment
As shown in Figure 1: a kind of horizontal fast-assembling traveling-grate stoker biomass boiler, it comprises boiler body 1 and flue gas system 2; Shown in Fig. 2-8: boiler body 1 comprises furnace wall 11, drum 12, traveling-grate stoker 13, face arch 14, rear arch 15, an air supply device 16 and a secondary air supply device; Drum 12 is installed in 11 tops, furnace wall, drum 12 and the furnace wall 11 outer heat-insulation layers 18 that also are provided with, furnace wall 11 comprises sidewall 111, antetheca 112 and rear wall 113, face arch 14 is formed by the top extension of antetheca 112, form preceding combustion chamber 131 between face arch 14 and the traveling-grate stoker 13, form after-burner 132 between rear arch 15 and the traveling-grate stoker 13; One time air supply device 16 provides combustion air (promptly coming combustion-supporting by airborne oxygen) for the organic-fuel on the traveling-grate stoker 13; The secondary air supply device comprises secondary main feed pipe 171, secondary props up air feed pipe 172 and secondary air blast 173, secondary main feed pipe 171 is located in the furnace wall 11 of preceding combustion chamber 131 and after-burner 132 sides, its air intake is connected with secondary air blast 173, secondary main feed pipe 171 is positioned on the tube wall of part of antetheca 112 and has air outlet, it is more than one that secondary props up air feed pipe 172, the end that every secondary props up air feed pipe 172 is connected 171 1 air outlet places of secondary main feed pipe, preceding combustion chamber 131 is led in the outlet of its other end, and promptly secondary props up air feed pipe 172 secondary main feed pipe 171 is communicated with preceding combustion chamber 131.
