Description
Technical field
The invention belongs to a kind of carbon black tail gas and coal mixed combustion, produce the boiler that steam is used for steam supply, generating.
Background technology
Carbon black tail gas is a kind of byproduct in the carbon black process, and its calorific value is very low, has only 650Kcal/Nm
3About, this gas seldom as the fuel of boiler, emitted sky as waste gas in the past usually.Along with the fast development of production of carbon black, carbon black tail gas output is increasing, can cause the significant wastage of the energy and serious environmental to pollute to the sky discharging.How effectively to utilize carbon black tail gas to become the major subjects that needs to be resolved hurrily in the production of carbon black.
Therefore completely newly developed the boiler of a kind of carbon black tail gas and coal mixed combustion, carbon black tail gas has been delivered to boiler, acted as a fuel, after coal mixed combustion, produced steam and be used for heat supply, generating, polluted thereby reduce, and improve energy utilization rate greatly.
Summary of the invention
The present invention overcomes the prior art problem, and a kind of novel carbon black tail gas and the boiler of coal mixed combustion are provided.
Realize above-mentioned purpose; The present invention adopts following technical scheme; The boiler of a kind of carbon black tail gas and coal mixed combustion; It is characterized in that: include burner hearth, horizontal flue, back-end ductwork, combustion apparatus and slag tap and ash discharge equipment, burner hearth, horizontal flue and back-end ductwork constitute Jiong type structure, and said combustion apparatus includes the layering coal bunker, clockwise flake type does not leak coal stove row and carbon black tail gas burner; Said slag tap with ash discharge equipment be installed in clockwise flake type do not leak coal stove row below; Said lower furnace portion and be positioned on the both walls that clockwise flake type do not leak coal stove row top the carbon black tail gas burner is installed is installed sectionalized superheater in the said horizontal flue, economizer and air preheater are set in the said back-end ductwork.
Through adopting such scheme, the present invention has the following advantages:
1, to the carbon black tail gas calorific capacity low, water content is high, unstable this characteristic of quantum of output, selects the mode of carbon black tail gas and coal mixed combustion for use, guarantees that carbon black tail gas in time catches fire, smooth combustion, thereby the assurance boiler operatiopn reliable and stable.
2, to these two kinds of different fuel of carbon black tail gas and coal, adopt carbon black tail gas burner and clockwise flake type not to leak the mode that coal stove row combines and organize burning, adopt grate firing to add suspension combustion, combustion intensity is high, fuel combustion fully, abundant.
Further setting of the present invention is: the bottom of said burner hearth and be positioned at fire grate top and arrange face arch and rear arch is provided with the water-cooled screen in the said burner hearth.Said lower furnace portion both walls all is equipped with the carbon black tail gas burner, and the carbon black tail gas burner is a vortex burner.
The advantage of the further scheme of the present invention is:
1, the combustion characteristics of based on fuel is mixed in order to impel in the burner hearth gas, and the flowing of tissue radiation and red-hot flue gas, and guarantees the moisture content evaporation and the vaporization rapidly of fresh fuel, makes fuel catch fire in time, burn, encircles before and after lower furnace portion is laid with.
2, the carbon black tail gas burner is arranged on the lower furnace portion both walls, is positioned at main burning block, guarantees that carbon black tail gas in time catches fire, burns under the radiation of high-temperature flue gas.
3, the carbon black tail gas burner is a vortex burner, and secondary air channel and carbon black tail gas pipe are equipped with swirl vane, and blade rotates air-flow, utilizes swirling eddy to be formed with to be beneficial to the recirculating zone that catches fire and mixes the strong air-flow carbon black tail gas that burns.Exit flow is strong rotating jet, and bigger angle of flare and recirculating zone, center are arranged, and guarantees to catch fire and flameholding.
4, after the rotation of carbon black tail gas and secondary wind mixes in the carbon black tail gas burner; Spray into the burner hearth internal combustion at a high speed; Utilize this swirling eddy to cause flue-gas swirl; Strengthen the disturbance of flue gas, the stroke of prolong smoke in stove, improve the degree of filling of gas stream in the stove, make two kinds in the fuel combustible completing combustion, burn.
5, adopt layering coal bunker and clockwise flake type not to leak coal stove row's combustion apparatus; By sieve lattice and the cylinder installed in the coal bunker; Raw coal is fallen on the fire grate by the variable grain layering, made big coal grain drop on the grate surface bottom, tiny coal grain drops on top; Improve the catching fire of coal, ventilation and burning condition, improved efficiency of combustion.
6, arrange some water-cooled screens in the burner hearth, under the certain situation of boiler height, can increase the radiation of burner hearth heating surface area greatly, reduce metal consumption, optimize boiler structure.
Below in conjunction with accompanying drawing the present invention is further described.
