Abstract
The utility model relates to a palm shell and palm fiber fueled boiler. The boiler adopts palm shells and palm fibers as fuels, and is used for generating steam for steam supply and power generation. According to the technical scheme, the palm shell and palm fiber fueled boiler comprises a boiler barrel, a steel frame, a hearth, a grate, slag and ash discharging equipment, a burnout chamber, three flues, a horizontal flue and a tail flue, wherein the hearth is arranged on the steel frame; the grate is arranged below the hearth; and the hearth is positioned above the grate, and is provided with a front arch, a rear arch and secondary air. The boiler is characterized in that the grate is a water-cooled shaking grate; and the burnout chamber, the three flues, the horizontal flue and the tail flue are sequentially arranged behind the hearth. According to the technical scheme, the palm shells and the palm fibers can be directly supplied into the palm shell and palm fiber fueled boiler for burning, and the generated steam can be used for power generation and steam supply.
Description
Technical field
The utility model relates to a kind of burning palm shell and monkey grass, and produces the boiler that uses palm shell and monkey grass that steam is used for steam supply, generating.
Background technology
Along with the rapid growth of world energy sources demand, global energy is supplied with and to be becoming tight in recent years, is that the conventional energy resource of representative will finally be exploited totally with coal, oil, and a large amount of these fossil fuels of use can cause a series of serious environmental pollution problems simultaneously.Therefore, whole world development and use strong to aboundresources, recyclability, the biomass resource that is conducive to improve environment and sustainable development have given great concern.Biomass fuel is as a kind of regenerative resource, and the grand strategy that has become various countries, world today reply global energy crisis and ecological environment crisis is selected.
Palm shell and monkey grass are the residues in the palm oil extractive process as a kind of biomass fuel, and resource is so not only wasted in abandoned always for a long time, also pollutes the environment.Utilize the burning of palm shell and monkey grass that the energy is provided, the steam that produces is used for generating and steam supply, not only have the social benefit of energy savings, minimizing environmental pollution, good economic benefits is also arranged.
Summary of the invention
The purpose of this utility model is that design can directly be delivered into boiler with palm shell and monkey grass and burn, and the steam that produces is used for generating electricity and the boiler that uses palm shell and monkey grass of steam supply.
Realize above-mentioned purpose, the utility model adopts following technical scheme, a kind of boiler that uses palm shell and monkey grass, comprise drum, steelframe, burner hearth, fire grate, slag tap and ash discharge equipment, burning chamber, three flues, horizontal flue and back-end ductwork, burner hearth is installed on the steelframe, fire grate is arranged on the below of burner hearth, the top that burner hearth is positioned at fire grate is provided with forward and backward arch and secondary wind, it is characterized in that: described fire grate is the water-cooled vibrating-grate stoker, after described burning chamber, three flues, horizontal flue and back-end ductwork are successively set on burner hearth.
Further setting of the present utility model is: protection tube, high temperature superheater, medium temperature overheater and low temperature superheater are installed in the described horizontal flue, economizer and air preheater are installed in back-end ductwork; The front of described burner hearth is positioned at water-cooled vibrating-grate stoker top and is provided with the charging gear of sowing grass seeds by duster.
Adopt such scheme, the utlity model has following beneficial effect:
1, adopts the water-cooled vibrating-grate stoker that fuel is moved down along with the vibration of fire grate, thereby prevent that fuel from making burn deterioration because piling up burning coking on grate surface.
2, flow through successively burner hearth, burning chamber, three flues, horizontal flue and back-end ductwork of the flue gas that produces in water-cooled vibrating-grate stoker burning of palm shell and monkey grass, flue gas flow is long, abundant cooled flue gas, prevent from influencing the boiler heat absorption because of coking, flue gas through three flues after, the temperature that enters horizontal flue has been lower than ash fusion point, can avoid coking on superheater surface.
3, at palm shell with the monkey grass ash fusion point is low, fugitive constituent is high, easy bonding and easily produce the characteristic of corrosion, the pattern that boiler has adopted the feed of sowing grass seeds by duster to combine with the water-cooled vibration, the charging gear of sowing grass seeds by duster can make fuel in the process of sowing grass seeds by duster, part fines fuel directly carries out suspension combustion aloft, and macro particles fuel also can be fallen equably and burns away sufficient combustion on the fire grate.
4, above fire grate, arrange suitable front and back arch, and at forward and backward arch place layout secondary wind, sow grass seeds by duster charging gear, water-cooled vibrating-grate stoker, front and back arch and secondary air system formed complete combustion system, can make palm shell and monkey grass completing combustion, reduce the flying dust amount in the flue gas, improve efficiency of combustion.
5, arrange protection tube in the horizontal flue, can make smoke distribution even, allow the superheater thermally equivalent, further reduce the superheater input gas temperature simultaneously, prevent the superheater coking.
Below in conjunction with accompanying drawing the utility model is further described.
