Abstract
The utility model relates to a clean burning boiler using soft coal and briquette. The utility model is mainly composed of a horizontal burning chamber, a vertical burning chamber, a coal adding door, a fire door, an ash door, a fire grate, a U-shaped separator, etc. The burning briquette is added into the horizontal burning chamber, is separated and burnt volatile matters and part of coke, is pushed into the vertical burning chamber to be continuously burnt, and is burnt out. The utility model has the advantages of low dust concentration, low Sox concentration, low fume blackness, simple structure, convenient coal adding and slag discharging, high burning strength, high heat efficiency, etc. The utility model is widely used as the industrial or living burning and heat exchange devices to heat steam and water.
Description
The utility model relates to a kind ofly makes the burner of fuel with bituminous coal, especially a kind of shaped coal of bituminous coal cleaning combustion boiler that burning and smoke elimination, dedusting, desulfurization is incorporated into one.
Existing back yard industry and domestic boiler, based on the coal combustion boiler that looses, along with the increasingly stringent of environmental protection standard, dust exhausting concentration, the indexs such as SOx concentration of emission, particularly blackness of exhaustion of the coal burning boiler that looses have been difficult to meet the demands.The moulded coal burning boiler of Chu Xianing in recent years, as the patent No. is the Chinese patent of CNS72154S5U, disclosed boiler adopts the forward combustion mode, makes fuel (occurring serious black smoke during the bituminous coal moulded coal) with anthracite briquette, and these coal resources with a lot of areas are incompatible; And the patent No. is---the disclosed boiler of CN2148263Y and CN2055917U, though adopted the reverse burning mode, though can solve the aflame phenomenon of smoldering of shaped coal of bituminous coal, but coal slagging-off mechanism more complicated, in servicely be easy to generate distortion, or combustion intensity is low, and the service capacity deficiency is so make the popularization of shaped coal of bituminous coal combustion technology be subjected to considerable restraint.
The purpose of this utility model provides a kind of boiler of making fuel with shaped coal of bituminous coal, by adopting positive and negative bilateral-firing mode and the dust separating device that combines, make boiler both satisfy environmental requirement, have simple in structure, convenient, the characteristics such as combustion intensity is big, thermal efficiency height of coal slagging-off again.
The utility model is realized in the following manner: the shaped coal of bituminous coal cleaning combustion boiler, comprise upright combustion chamber, firing door, Hui Men, convection bank, fire grate, furnace wall and chimney, the sidewall on upright combustion top, chamber that is characterised in that of the present utility model is provided with the horizontal firing chamber, and firing door is installed in the outer end of horizontal firing chamber; On the sidewall of the bottom, upright combustion chamber that fire door is installed, fire grate is contained in the lower end of upright combustion chamber, and ash door is installed on the furnace wall of fire grate below; Before upright combustion bottom, chamber, convection bank, U type separator is installed.The quantity of the horizontal firing chamber that is provided with on the internal combustion chamber upper portion side wall is 1-6, can discharge 1-8 piece moulded coal on the width of each horizontal firing chamber, can discharge three stratotype coals on the depth direction.The fire grate vertical connection of upright combustion chamber and its lower end, each horizontal firing chamber and upright combustion chamber vertical connection, the horizontal firing chamber is 300～1000mm apart from the vertical range of fire grate.Firing door is provided with the adjustable wind of circulation area hole, and its percentage of air passage is 10%～30%.
Characteristics such as the utility model is owing to adopt the bilateral-firing mode of positive and negative combination, and with U type separator flue gas handled, and makes boiler have original dust exhausting concentration step-down, and the SOx discharge capacity is few, and oke exhaust blackness is low can satisfy the regional environmental protection index requirement of a class environmental protection.
Description of drawings: Fig. 1 is a structural representation of the present utility model
Below in conjunction with accompanying drawing, the utility model is elaborated.
The shaped coal of bituminous coal cleaning combustion boiler mainly is made up of horizontal firing chamber 1, upright combustion chamber 2, firing door 3, fire door 4, ash door 5, fire grate 6, U type separator 7, convection bank 8, furnace wall 9, chimney 10 etc.Firing door 3 is installed in the outer end of horizontal firing chamber 1, and one or more moulded coal can be discharged on the width of horizontal firing chamber in the lower end, inner end of one or more horizontal firings chamber and a upright sidewall vertical connection that fires chamber 2, can discharge three stratotype coals on the depth direction.Fire door 4 is installed on the sidewall at upright combustion 2 middle parts, chamber, and fire grate 6 is in upright combustion perpendicular joining of 2 lower ends, chamber; On the furnace wall of fire grate 6 belows, ash door 5 is installed.Be equiped with the adjustable wind of circulation area hole on firing door 3 and ash door 5, the primary and secondary air for moulded coal burning usefulness feeds naturally respectively.Be installed in for flue dust separatory U type separator 7 before the downstream, convection bank 8 of upright combustion chamber 2.
After shaped coal of bituminous coal joins horizontal firing chamber 1 from firing door 3, because the heat transfer effect of horizontal firing chamber 1 inner end high-temperature flue gas radiant heat and indoor combustion coal makes moulded coal dry gradually, and slowly separates out fugitive constituent.The air that is fed by firing door adds in flowing along the moulded coal honeycomb hole gradually, and the moulded coal that early adds in the horizontal firing chamber 1 constantly advances inwards, and temperature continues to raise, and fugitive constituent continues to separate out and burn.The combustion heat of fugitive constituent and the radiant heat of burner hearth ignite the coke on moulded coal surface gradually, and gradually from inside to outside, to internal extended, realize burning in the other direction by the surface.When moulded coal stops three coals after the time interval in horizontal firing chamber 1, the fugitive constituent more than 95% is separated out, and at this moment, just can translate into upright combustion chamber 2, under the secondary wind actions that ash door 5 feeds, carries out forward combustion, makes the further after-flame of coke.The flue gas that burning produces enters U type separator 7 by upright combustion 2 tops, chamber, realizes that gas dirt separates, and the further heat exchange of flue gas after being purified and convection bank, cooling back are discharged by chimney 10.The lime-ash in coke afterburnt is fallen by fire grate 6, discharges from ash door 5.
Under this combustion system, the fugitive constituent of shaped coal of bituminous coal is separated out at low temperatures, and speed of separating out is slow, and separates out fugitive constituent in the process with flow of flue gas, must be through the high-temperature space of top, upright combustion chamber.High temperature and the wind action of furnace bottom secondary have guaranteed the abundant burning of combustible in the fugitive constituent, have eliminated the black smoke phenomenon during shaped coal of bituminous coal is just burning.
The utility model boiler structure is simple, the coal slagging-off is convenient, combustion intensity is big, the thermal efficiency is high, can be widely used in places such as heat hot water, boiling water, steam in industrial production and the life, has very high economy, society and environmental benefit.
