Description
Technical field
It is the boiler heating power system of fuel with the biological particles that the utility model relates to a kind of.
Background technology
Existing boiler generally is to use forms such as fire coal, fuel oil, electrical heating to produce steam; Coal-fired, oil burning boiler is strong excessively to the fossil fuel dependence, fossil fuel is human valuable source, for the progress of human society plays a significant role; But a kind of non-renewable resource of fossil fuel; Product after the burning of fossil fuel can cause great pollution to environment simultaneously, is global warming like the carbon dioxide that discharges, and the nitrogen oxide of discharging and sulfur dioxide can form acid rain; Acid rain can destroy building again, deforestation, polluted lake.Phenomenons such as existing fire coal, fuel oil and electric heating equipment all need a large amount of fossil fuels, particularly coal-burning boiler, and the ubiquity thermal efficiency is on the low side, and the waste resource is serious; Oil burning boiler causes country that the dependence of oil is strengthened; The electrically heated boiler use cost is too high, and most of enterprises are difficult to bear.
Be that oil burning boiler, coal-burning boiler and electric boiler all are a kind of dependences to fossil fuel, fossil fuel is a kind of non-renewable resource, and the utility model is exactly to solve the dependence of boiler to fossil fuel.
Summary of the invention
It is the boiler heating power system of fuel with the biological particles that the purpose of the utility model provides a kind of, and its burning fully, the thermal efficiency is high, environment is not polluted.
The technical scheme of the utility model is: the boiler heating power system is made up of boiler body, economizer, tar processor, sack cleaner, air-introduced machine, feeding system; Feeding system connects boiler body; Economizer places above the boiler body; Economizer connects the tar processor through pipeline, and the tar processor is connected with sack cleaner, and sack cleaner is connected with air-introduced machine; Boiler body by drum and interior water screen tube thereof, constitute built-in face arch in combustion chamber and rear arch at the combustion chamber of drum bottom, the traveling-grate stoker of bottom, combustion chamber.
The boiler heating power system of the utility model is in the process of control burning; Biomass molding fuel is inserted the vaporizer (also claiming first combustion chamber) of gasification direct-fired furnace, and raw material leans on the rear arch temperature reflection igniter fuel of boiler, and traveling-grate stoker moves forward uniformly; What supported burning this moment mainly is the volatile matter composition of raw material; Burner hearth is in the micro-vacuum state burning, need not replenish air during the burning of first Room, and comparing with traditional coal-burning boiler is without the air blast air blast.Complete when volatile combustion, the only remaining fixed carbon of raw material has only fixed carbon and ash content to exist this moment on fire grate, since anoxycausis, the CO that volatile combustion generates
2React with fixed carbon, mainly contain steam, hydrogen, carbon monoxide, carbon dioxide, methane, tar and other hydrocarbon.This moment, burner hearth was in the micro-vacuum state burning, in this process, still need not replenish air burning.Under the effect of air-introduced machine; Fuel gas gets into the 3rd combustion chamber; Replenish the gas completing combustion that air makes generation this moment; Because a large amount of combustion gas is risen the temperature of secondary furnace in the burning of gasification secondary furnace and is formed thermal current, be radiated on the high-temperature heat pipe in the boiler through thermal current, and water is heated rapidly.In the burning of the 3rd Room, burner hearth is in a slight positive pressure state burning.
The utility model boiler body combustion chamber is divided into three combustion chambers by face arch and rear arch, adopts light-duty traveling-grate stoker to realize the mechanization burning, is furnished with air-introduced machine, carries out force ventilation.Biomass granule fuel is sent into hopper through belt conveyor; Fall entering burner hearth burning on the traveling-grate stoker from hopper; After the high-temperature flue gas that burning produces gets into the drum heat exchange through furnace outlet; Flue gas gets into economizer through the front smoke box top exit and accomplishes UTILIZATION OF VESIDUAL HEAT IN, after the low-temperature flue gas of economizer exit gets into the detar of tar processor, gets into the sack cleaner dedusting, and the clean tail gas after dedusting enters atmosphere through air-introduced machine forced ventilation to chimney.The fuel combustion lime-ash that the back produces that finishes is delivered to slag-removing hopper through traveling-grate stoker, transports to reclaim through slag remover or labor cleaning's pack and makees fertilizer.
The boiler heating power system of the utility model is fuel with the biological particles, and its burning is complete, and no tar produces, and the thermal efficiency is high, and the grey quantity of slag is little, and the nitrogen oxide discharge capacity is little, and tail gas reaches zero-emission, and environment is not polluted.
Description of drawings
Fig. 1 is the boiler heating power system architecture sketch map of the utility model.
Among the figure, 1-boiler body, 2-economizer, 3-tar processor, 4-sack cleaner; The 5-air-introduced machine, 6-electrical control cubicles, 7-feeding system, 8-face arch, 9-rear arch; The 10-water screen tube, 11-drum, 12-vapor outlet port, 13-traveling-grate stoker, 14-air compartment; The 15-combustion chamber, A-first combustion chamber, B-second combustion chamber, C-the 3rd combustion chamber.
The specific embodiment
As shown in Figure 1; The boiler heating power system of the utility model is made up of horizontal steam boiler body 1, economizer 10, tar processor 3, sack cleaner 4, air-introduced machine 5, feeding system 7, electrical control cubicles 6, softened water tank 2 etc.; Feeding system 7 connects boiler body 1, and economizer 2 places above the boiler body, and economizer 2 connects tar processor 3 through pipeline; Tar processor 3 is connected with sack cleaner 4, and sack cleaner 4 is connected with air-introduced machine 5.Boiler body 1 is by drum 11 and interior water screen tube 10 thereof, constitute at the combustion chamber 15 of drum bottom, the traveling-grate stoker 13 of bottom, combustion chamber; Built-in face arch 8 in combustion chamber and rear arch 9; Form three combustion chambers; First, second, third combustion chamber A, B, C are air compartment 14 below traveling-grate stoker 13.Adopt light-duty traveling-grate stoker to be furnished with air blast etc. and carry out force ventilation.
Running water gets into Na-ion exchanger and softens back entering softened water tank, and boiler feed pump draws water from softened water tank boiler is fed water, and after exit of pump gets into the economizer preheating, gets into drum.Biomass granule fuel is sent into hopper through belt conveyor; Fall entering burner hearth burning on the traveling-grate stoker from hopper; The high-temperature flue gas that burning produces; In the flow of flue gas process, rely on the temperature difference of cigarette G&W to carry out heat exchange generation steam, the steam of generation gets into economizer by the boiler top through outlet and accomplishes UTILIZATION OF VESIDUAL HEAT IN.
