Description
Technical field
The utility model relates to a kind of boiler, especially relates to a kind of biomass-burning steam boiler.
Background technology
Biomass boiler is to take living beings as raw material, a kind of boiler that the mode such as adopt gasification, solidify is fuel by biomass conversion.The raw material of biomass boiler is very extensive, so long as all can through photosynthetic wooden idle material, such as wood fragments bits, rice husk, sunflower seed shell, sorghum stalk, cornstalk, beans stalk etc., high temperature, high pressure, after specially-shaped mechanism is pressed into cylindrical particle fuel, put in the boiler of special manufacture, just can produce sufficient heat, the slag of its generation still can be used as potash fertilizer supply crops, and existing biomass boiler exists the problems such as the thermal efficiency is low, biomass undergoes adaptation is narrow, operating cost is high.
Summary of the invention
The purpose of this utility model is: the biomass-burning steam boiler that a kind of thermal efficiency is high, biomass undergoes adaptation is strong, operating cost is low, safe and reliable is provided.
The technical solution of the utility model is: a kind of biomass-burning steam boiler, comprise two drums that longitudinal is arranged, burner hearth both sides are furnished with water-cooling wall, water-cooling wall upper end and upper drum welding, water-cooling wall lower end respectively with a left side, right header welding, after burner hearth, between upper lower drum, be welded with the convection bank of in-line arrangement, between convection bank, be provided with multiple tracks brick baffle, soot blower is housed in convection bank, burner hearth comprises combustion chamber and burning chamber, furnace front is equipped with secondary air channel and explosion proof door, the below of combustion chamber has traveling-grate stoker, fire grate is provided with both sides averaging wind pipe, fire grate top is furnished with face arch, the built-up arch that rear arch forms.
Described secondary air channel is connected with air preheater with averaging wind pipe.
Described face arch and rear arch adopt multistage removable refractory brick moulding arch.
The beneficial effects of the utility model are: owing to adopting two drum longitudinals to arrange, burner hearth both sides are furnished with water-cooling wall, are welded with the convection bank of in-line arrangement between upper lower drum, and in convection bank, are furnished with soot blower, and compact conformation is elegant in appearance.Chamber design is become to combustion chamber and burning chamber's two parts, be conducive to the smoke abatement and dust control in stove, and advantageously strengthened the burning of fuel in combustion chamber, fly ash combustible material and fly ash content have been reduced, and adopt multistage removable refractory brick moulding to encircle, intensity is good, and radianting capacity is strong, is conducive to burning of the combustibles such as fly ash combustible material, lime-ash.Secondary air channel is further combustion-supporting, and explosion proof door prevents detonation, and secondary air channel is connected with air preheater with averaging wind pipe, has improved fire box temperature.The utility model utilizes fuel and the combustion characteristics of living beings, makes boiler reach that adapted biomass kind is wide, after-flame degree is good, efficiency is high, the effect that operating cost is low, safe and reliable, disposal of pollutants is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
From structural representation of the present utility model shown in Fig. 1, can find out, the utility model comprises two drums that longitudinal is arranged, burner hearth 13 both sides are furnished with water-cooling wall 6, water-cooling wall 6 upper ends and upper drum 1 welding, water-cooling wall 6 lower ends respectively with left and right header welding, after burner hearth 13, on be welded with the convection bank 7 of in-line arrangement between lower drum, 7 of convection banks, be provided with multiple tracks brick baffle 11, soot blower 8 is housed in convection bank 7.At 7 design multiple tracks brick baffles of convection bank, flue gas in burning chamber is entered after convection bank, repeatedly turn back, flue gas is in exhumation process, flue dust and brick baffle 1 in flue gas, with convection bank 7 repeatedly wash away collision, when turning back, flue gas forms vortex herein, centrifugal force when utilizing the inertia force of flue gas and brick baffle, tube bank collision and forming vortex carries out dedusting, adopt this measure, boiler body initial dust-density emission, far below national regulation, is conducive to reduce the pollution of boiler smoke to atmospheric environment.Burner hearth 13 comprises combustion chamber and burning chamber, and secondary air channel 12 and explosion proof door 2 are equipped with in burner hearth 13 front portions, and secondary air channel 12 is connected with air preheater with averaging wind pipe.Burner hearth 13 is designed to combustion chamber and burning chamber's two parts, and has installed secondary air channel 12 additional, advantageously strengthened the burning of living beings in combustion chamber, and strengthened the flue gas flow area of burning chamber, reduced fly ash combustible material and fly ash content.The below of combustion chamber has traveling-grate stoker 4, and fire grate 4 is provided with both sides averaging wind pipe, isobaric ventilation.Fire grate 4 tops are furnished with the face arch 5 into living beings overheavy firing, the built-up arch that rear arch 10 forms, and face arch 5 and rear arch 10 adopt multistage removable refractory brick moulding arch, and this arch intensity is good, and radianting capacity is strong, is conducive to burning of the combustibles such as fly ash combustible material, lime-ash.Fire grate adopts novel bulk grate without coal leakage, moves light reliably, has substantially realized the fire grate segment that is heated and has not been subject to pulling force, not fragile, and ventilation condition is good, has certain for deashing ability.
Burning flow process of the present utility model: during this type normal operation of boiler, fuel passes through cinder door from feed hopper, after striking off, with fire grate, enter lentamente the precombustion chamber under burner hearth face arch, fuel in the preheating under the hot-air of air preheater heating and the heat of face arch radiation entering through fire grate bottom in precombustion chamber, be dried, separate out after fugitive constituent, enter combustion chambers burn, the flue gas producing after burning enters convection bank through burning chamber, by convection bank, enter air preheater, deduster, then by air-introduced machine, take out and draw, by chimney discharged to atmosphere.
