Description

Full-automatic horizontal hot-air boiler

Technical field

The present invention relates to boiler, be specifically related to a kind of full-automatic horizontal hot-air boiler.

Background technology

Existing hot-air boiler is burner hearth and fire-tube type structure, because unreasonable structure makes that the thermal efficiency of boiler is low, and the smoke pipe easy blocking, but repair very inconvenience, thus exist operating cost high, the shortcoming that efficiency is low and leaving air temp is low.

Summary of the invention

It is unreasonable to the invention solves existing boiler structure, has the low and susceptible to plugging problem of smoke pipe of the thermal efficiency, and a kind of full-automatic horizontal hot-air boiler is provided.

The present invention realizes through following technical scheme:

A kind of full-automatic horizontal hot-air boiler offers cool air inlet and automatic stoking mouth on the refractory material furnace wall, front side, cool air inlet is located at automatic stoking mouth top; Be provided with automatic traveling-grate stoker in the body of heater of automatic stoking mouth bottom; Offer hot-air collection case and outlet and blast orifice on the rear side refractory material furnace wall, the terminal bottom of furnace body of traveling-grate stoker offers slag notch automatically, is provided with chimney arch in the body of heater; Last chimney arch is divided into body of heater the cold air heat transfer zone on the combustion zone and the top of bottom; Combustion zone and cold air heat transfer zone are communicated with through the heat exchange box smoke inlet, are provided with rear arch between last chimney arch and the automatic traveling-grate stoker, are provided with the smoke box of three to seven connections in the cold air heat transfer zone; Be provided with the smoke box dividing plate that friendship is up and down arranged between the smoke box; Be provided with heat-transfer pipe and smoke box passage in each smoke box, offer exhanst gas outlet on the refractory material furnace wall at terminal smoke box top, offer the deashing inspection socket on the refractory material furnace wall of smoke box sidewall.

Fuel gets into coal feed point through the automatic stoking mouth, after under the automatic chain fire-gate effect ribbing being carried out transpiring moisture to dry distillation area, gets into coal gas generating region generation coal gas again; The coal gas of generation is after under the effect of air-introduced machine fully burn in entering arch combustion chamber in burning back again, and it is interior after the heat absorption of first heat-transfer pipe that the heat of generation gets into smoke box through the heat exchange box smoke inlet, gets in second heat-transfer pipe through the first smoke box passage; Get in the 3rd heat-transfer pipe through the second smoke box passage again; Circulation gets in the terminal heat-transfer pipe successively, gets in the terminal smoke box again; Get into desulphurization plant through exhanst gas outlet, under the effect of air inducing, enter atmosphere.

Coal is under automatic chain fire-gate effect; At first carry out destructive distillation at dry distillation area; Produce coal gas in the mixed gas generating region again, after be transported to the coke district and burn, get into the fixed carbon district again and get into clinker area at last and get into automatic mucking machine by slag-drip opening and clear up; Whole process, speechless no environmental protection and energy conservation automation mechanized operation.Under the effect of ventilation blower, cold air gets into body of heater by cool air inlet, after terminal heat-transfer pipe heat absorption, gets in the terminal air zone, and circulation gets in the hot-air collection case at last successively, delivers to and uses the hot-air district, and whole process operation is stable, and the thermal efficiency is high.

The present invention uses coal, coal dust, biomass fuel, moulded coal etc. to act as a fuel, and can be widely used in hot air stove, Industrial Boiler, heating boiler, steam boiler, and the thermal efficiency is high, and is easy to maintenance.
