Abstract
The utility model discloses a fire energy -efficient extreme misery of living beings pipe steam boiler, put the formula shell including indulging, the combustion chamber is constituteed to shell, water -cooling wall, and a plurality of screw thread tobacco pipes are arranged inside the shell, are welded with the both ends tube sheet respectively, and convection heating surface is constituteed to the wing section flue and the screw thread tobacco pipe in the shell of furnace both sides. The utility model discloses thermal efficiency height, living beings strong adaptability, environmental protection safety.
Description
Technical field
The utility model relates to a kind of boiler, especially relates to a kind of biomass combustion efficient energy-saving steam boiler.
Background technology
Biomass boiler take living beings as raw material, and biomass conversion is a kind of boiler of fuel by the modes such as employing gasification, solidification.The raw material of biomass boiler widely, as long as 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, be pressed into after cylindrical particle fuel through specially-shaped mechanism, put in the special boiler manufactured, just can produce sufficient heat, its slag produced still can as potash fertilizer supply crops.
Summary of the invention
The purpose of this utility model is: provide that a kind of thermal efficiency is high, biomass undergoes adaptation is strong, the biomass-burning steam boiler of Environmental Safety.
The technical solution of the utility model is: the energy-conservation water-fire tube steam boiler of a kind of biomass combustion efficient, comprise longitudinal shell, shell, water-cooling wall composition combustion chamber, burner hearth both sides are furnished with water-cooling wall, water-cooling wall upper end is welded with shell, water-cooling wall lower end respectively with left and right header welding, multiple threaded flue be arranged in shell inside, respectively with two ends Tube-sheet Welding, threaded flue composition convection heating surface in the aerofoil profile flue of burner hearth both sides and shell, lower furnace portion arranges traveling-grate stoker, the built-up arch that fire grate top is furnished with face arch, rear arch is formed.
Further, be respectively equipped with an inspection opening before and after burner hearth, before burner hearth, be provided with explosion-protection equipment.
The beneficial effects of the utility model are: the utility model adopts new type water fire tube structure, and burner hearth both sides are furnished with aerofoil profile flue, and shell inside is welded with the convection bank of energy-efficient threaded flue composition, and compact conformation is elegant in appearance.During this normal operation of boiler, fuel passes through cinder door from feed hopper, the precombustion chamber under burner hearth face arch is entered lentamente with fire grate after striking off, the preheating under the hot-air of air preheater heating and the heat of face arch radiation that fuel enters through fire grate bottom in precombustion chamber, dry, after separating out fugitive constituent, enter combustion chambers burn, combustion chamber is oxygen and the exothermic main place of combustible generation chemical reaction, take into full account combustion space, air capacity, thermic load, therefore, sufficient combustion can be reached, eliminate the ideal state of flue dust, the flue gas produced after burning enters through aerofoil profile flue the convection bank that threaded flue forms by burner hearth, air preheater is entered by convection bank, deduster, then taken out by air-introduced machine and draw by chimney discharged to air.The thermal efficiency is high, and biomass undergoes adaptation is strong, and Environmental Safety is safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As can be seen from structural representation of the present utility model shown in Fig. 1, the utility model adopts new type water fire tube structure longitudinal to arrange, single shell 1 longitudinal is arranged, and burner hearth 5 both sides are furnished with water-cooling wall, upper end is welded with shell 1, lower end respectively with left and right header welding.It is inner that multiple threaded flue 2 is arranged in shell 1, respectively with two Tube-sheet Welding.Form combustion chamber by shell 1, water-cooling wall, the threaded flue 2 in the aerofoil profile flue of burner hearth 5 left and right sides and shell forms convection heating surface, and boiler tail arranges economizer separately.Wing flue can reduce high-temperature pipe plug of tobacco temperature, thus slows down subcooled boiling, reduces shell lower curtate thermic load, prevents tube sheet cracking, prevent bulge.Threaded flue 2 augmentation of heat transfer, obviously reduces smoke pipe radical and reduces shell size, improves flexible, reduces pipe end weld seam thermal stress, saves steel not dust stratification, prevent tube sheet cracking.This boiler adopts traveling-grate stoker 6, and fire grate 6 top is furnished with the built-up arch 8 into the face arch of living beings overheavy firing, rear arch are formed.Be respectively equipped with an inspection opening 9 before and after burner hearth 5, burner hearth 5 is provided with explosion-protection equipment 3 above, is convenient to the explosion-proof demand of maintenance and inspection and boiler.Combustion apparatus (fire grate) adopts the isobaric aeration structure of both sides averaging wind pipe, the technology such as air zoning, burner hearth adopts variable furnace arch structure, be provided with front and back segmentation air compartment, be furnished with the air preheater providing hot blast, overheavy firing improves fire box temperature, and adopt the shaping arch of multistage removable refractory brick, this arch intensity is good, and radianting capacity is strong, is conducive to burning of the combustible such as fly ash combustible material, lime-ash.Chamber design is become combustion chamber and burning chamber's two parts, is conducive to the smoke abatement and dust control in stove, and the favourable burning enhancing fuel in combustion chamber, reduce fly ash combustible material and fly ash content, boiler bottom is provided with ash hole 7.This boiler is in conjunction with the fuel of living beings and combustion characteristics, and make boiler reach adapted biomass kind wide, after-flame degree is good, the effect that disposal of pollutants is low.
Burning flow process of the present utility model: during this type normal operation of boiler, fuel passes through cinder door from feed hopper 4, the precombustion chamber under burner hearth face arch is entered lentamente with fire grate 6 after striking off, fuel the preheating under the hot-air of air preheater heating and the heat of face arch radiation entered through fire grate bottom in precombustion chamber, drying, after precipitation fugitive constituent, enter combustion chambers burn, combustion chamber is oxygen and the exothermic main place of combustible generation chemical reaction.Combustion space, air capacity, thermic load has been taken into full account during design.Therefore, can sufficient combustion be reached, eliminate the ideal state of flue dust.The flue gas produced after burning enters through aerofoil profile flue the convection bank that threaded flue 2 forms by burner hearth 5, enters air preheater, deduster, then taken out by air-introduced machine draw by chimney discharged to air by outlet flue 10 by convection bank.
