Abstract
The invention provides a waste incineration boiler, which ensures that a conventional waste incineration boiler is less in dust stratification, convenient in soot cleaning and difficult in leakage, and the operation and maintenance costs of the boiler are reduced. The waste incineration boiler comprises a furnace chamber, a furnace grate and a horizontal flue, wherein the furnace chamber is positioned above the furnace grate; a boiler barrel is arranged above the furnace chamber; a front-back arch is arranged on the lower part of the furnace chamber; secondary air is arranged on the front-back arch, and faces the furnace grate; and an air preheater, an overheater and an evaporator are arranged in the horizontal flue. The waste incineration boiler is characterized in that: the furnace chamber is connected with a vertical burn-out chamber, three vertical flues, the horizontal flue and a tail part vertical flue in turn; a coal economizer is arranged in the tail part vertical flue; a rapping apparatus is arranged on a pipeline of the air preheater, the overheater and the evaporator which are arranged in the horizontal flue; and a shockwave or steam sootblower is arranged in the tail part vertical flue.
Description
Technical field
The present invention relates to the technical field of garbage incinerating system, be specially garbage burning boiler.
Background technology
The domestic characteristics that rubbish ubiquity calorific value is low, moisture content is high, ash is high will be burnt rubbish fully, and effectively suppressed the generation of harmful substances such as dioxin, need each parts of scientific and reasonable layout boiler.
In the burning field, what domestic employing was maximum is the stoker fired grate incinerator at present, and the basic structure form has vertical layout and horizontal layout.The boiler of vertical layout, its convection heating surface pipe is horizontal arrangement all, dust stratification very easily, even adopt shock wave or steam or sound wave ashing, continuous operating time is also shorter; The boiler of horizontal layout, its convection heating surface pipe arranges that vertically the dust stratification degree is light slightly, generally adopts vibration dust-cleaning, continuous operating time is long slightly, but the economizer part is because the effect of beater be prone to leakage phenomenon, and operation expense is higher.
Summary of the invention
To the problems referred to above, the invention provides garbage burning boiler, it makes, and conventional garbage burning boiler dust stratification is few, deashing convenient, be difficult for leakage, and reduces the boiler operatiopn maintenance cost.
Garbage burning boiler; Its technical scheme is such: it comprises burner hearth, fire grate, horizontal flue, and said burner hearth is positioned at the top of said fire grate, and the top of said burner hearth is provided with drum; Arch before and after the bottom of said burner hearth is provided with; Said front and back arch is gone up and is arranged secondary wind, and said secondary wind is furnished with air preheater, superheater, evaporimeter towards said fire grate in the said horizontal flue; It is characterized in that: said burner hearth connects vertical burning chamber, vertical three flues, horizontal flue and afterbody vertical gas pass in order; Be furnished with economizer in the said afterbody vertical gas pass, be furnished with rapping apparatus on the pipeline of the said air preheater in the said horizontal flue, superheater, evaporimeter, arrange shock wave or steam sootblower in the said afterbody vertical gas pass.
It is further characterized in that: the superheater in the said horizontal flue specifically comprises high temperature superheater, medium temperature overheater, low temperature superheater; Said air preheater, high temperature superheater, medium temperature overheater, low temperature superheater, evaporimeter are arranged in the said horizontal flue in order; Be furnished with attemperator between said high temperature superheater, the medium temperature overheater; Be furnished with attemperator between said medium temperature overheater, the low temperature superheater, be furnished with said rapping apparatus on the pipeline of said air preheater, high temperature superheater, medium temperature overheater, low temperature superheater, evaporimeter;
The rubbish hopper is installed on the front wall of said lower furnace portion, and said lower furnace portion side wall is equipped with auxiliary burner.
After adopting structure of the present invention, rubbish is delivered on the fire grate through hopper, under the cooperation of front and back arch and secondary wind, fully burns, burns; The flue gas that produces flow through successively burner hearth, burning chamber, three flues, horizontal flue and afterbody vertical gas pass; Form five backhauls and flow to, flue gas is cooled off in burner hearth, burning chamber, three flues fully, has effectively prevented the high temperature corrosion of back-end surfaces; In horizontal flue, arrange flue gas air preheater, superheater and the evaporimeter of vertical level; Because the gravity effect is difficult for dust stratification, mainly adopts vibration dust-cleaning, general effect is better; In the afterbody vertical gas pass economizer is set; This place's flying dust is less relatively; The cigarette temperature is also lower, adopts shock wave, steam sootblower to blow ash and can obtain good ash-removal effect, thoroughly avoided domestic and international many because the leakage phenomenon that rapping causes; So it makes that conventional garbage burning boiler dust stratification is few, deashing convenient, is difficult for leaking, and reduces the boiler operatiopn maintenance cost.
