Abstract
The utility model relates to a powdered coal and coal gas dual-use boiler, which is characterized in that two slit type air-bag gas rectangular blast boiler coal gas ejector nozzles arranged from top to bottom are arranged on the combustor of the boiler, air ejector nozzles are arranged around the ejector nozzle on the rectangular blast boiler, the cross section proportion of the air ejector nozzle and the coal ejector nozzle of the blast boiler is (3 to 4):5; a powdered coal ejector nozzle is arranged in the center of the combustor, and a sleeve type coke boiler spray nozzle is respectively arranged inside a second air ejector nozzle on the upper layer of air ejector nozzle, and a second air ejector nozzle on the lower layer. The utility model has the advantages that the boiler not only can be operated by the full combustion of the powdered coal, but also can be operated by the full combustion of the coal gas, the exhaust gas resources such as blast boiler gas or coke boiler gas produced during the production process of metallurgical enterprises can be efficiently utilized, the resource can be saved, the production cost can be reduced and the environment can be improved.
Description
Technical field
The utility model relates to a kind of station boiler, particularly a kind of coal dust coal gas boiler for dual purpose.
Background technology
Along with the increase of steel enterprise production capacity, the generating capacity of blast furnace gas effectively utilizes this part coal gas resource also along with rolling up in recent years, reduces coal gas diffusion, reduce production costs, and be the problem that solve.Existing station boiler generally all is the station boiler of pulverized-coal fired boiler or a small amount of coal gas of coal dust admixture.
Summary of the invention
The purpose of this utility model provides a kind of coal gas resource of utilizing and satisfies smelter production needs, the coal dust coal gas boiler for dual purpose that can use coal gas with coal dust again that reduces production costs.
Coal dust coal gas boiler for dual purpose, it is characterized in that: the burner of this boiler is provided with two slit bellows chamber gas rectangle blast furnace gas spouts arranging up and down, this spout is a wind snout around rectangle blast furnace gas spout, and the wind inlet is (3-4) with the section ratio of blast furnace gas spout: 5; The coal dust spout is arranged in the burner center, is furnished with bushing type coke-stove gas nozzle in upper strata overfire air port and lower floor's overfire air port.
Compared with prior art, the utility model has the advantages that: this boiler can move by the clean burn coal dust, can move by clean burn coal gas again, can effectively utilize waste gas resource that smelter produces in process of production such as blast furnace gas, coke-stove gas, energy savings reduces production costs, and improves environment.
