Abstract
The utility model relates to a gas and coal mixing boiler. The gas and coal mixing boiler comprises a boiler shell and a hearth installed inside the boiler shell, wherein the boiler shell is provided with a coal inlet and a slag outlet which are communicated with the hearth; a water interlayer is arranged between the hearth and the boiler shell; the upper portion of the hearth is provided with a breaking-out port used for spraying alight combustible gas into the hearth; the lower portion of the hearth is provided with a burning frame used for placement of fire coal. The gas and coal mixing boiler further comprises a negative pressure dust removal machine which is connected with the hearth through a pipeline and used for pumping gas inside the hearth out, and the other end of the negative pressure dust removal machine is connected with the breaking-out port in the upper portion of the hearth and used for feeding dedusted gas into the breaking-out port for ignition. The gas and coal mixing boiler is simple in structure, high in thermal utilization efficiency, economical and practical.
Description
Technical field
The utility model belongs to field of boilers, relates in particular to a kind of bottle coal mixing boiler.
Background technology
Along with the continuous increase of population, energy resource consumption continues to increase, and boiler is as the conventional plant equipment of people, and its energy consumption is more and more subject to people and pays close attention to, and various power economized boilers constantly emerge in large numbers, but effect is all undesirable.
Summary of the invention
The purpose of this utility model is to provide a kind of bottle coal mixing boiler, solves existing boiler hot utilization rate low, the problem of pollution that caused by coal burning environment.
For achieving the above object, a kind of bottle coal mixing boiler of the present utility model, comprise furnace shell and be arranged on the burner hearth in furnace shell, furnace shell is provided with the coal feeding hole and the slag notch that lead to burner hearth, between described burner hearth and furnace shell, be arranged at water interlayer, described upper furnace is provided with bocca, for the fuel gas of lighting is sprayed into burner hearth; Described lower furnace portion is provided with burning rack, for placing fire coal; Also comprise a depression dust-removing machine, be connected with burner hearth by pipeline, for the gas in burner hearth is extracted out, the described depression dust-removing machine other end is connected with the bocca of upper furnace, lights for the gas after dedusting is sent into bocca.
Further, upper furnace is provided with air intake.
Bottle coal mixing boiler of the present utility model, the fuel gas that utilization is lighted adds boiler, simultaneously due to effectively heating boiler bottom of fuel gas, so add coal-fired auxiliary heating in boiler bottom, the fuel gas of lighting is owing to there being certain distance from burning rack, can not make coal completing combustion, so by a depression dust-removing machine is set, the fuel gas such as the CO of the imperfect combustion generation in colliery are carried out to dedusting, and circulation passes into the bocca processing of burning, save the energy, improved heat utilization efficiency.
The utility model is simple in structure, and heat utilization efficiency is high, economical and practical.
