Description

Separate assembling multifunction burning coal stove

Affiliated technical field

The utility model belongs to a kind of device in the thermal power transfer field, be for family civilian have a multiple function, non-pressure hot water heating coal furnace.

Background technology

Known in the market vertical water sleeve type boiler, its principal character are to be with a water jacket outside the irony burner hearth, and recirculated water directly absorbs heat from burner hearth, and expanded by heating is delivered to radiator after body of heater top delivery port enters pipeline with heat energy.The coal-fired flue gas that produces in the burner hearth is directly discharged through chimney from the fire door top.This kind structure of furnace body has been because of the effect of water-cooling wall has reduced temperature in the stove, coal can not fully be burnt and produces half-cooked charcoal, makes heat be lost to space (estimated loss is about 40%) because of direct smoke evacuation again, so the thermal efficiency utilization of this kind cooking stove is not high.The water jacket of this kind body of heater is the inner bag that cylinder iron pours into a sealing, and it is also very difficult therefore to remove incrustation scale.This kind body of heater is to be major function with the heating, and can not use other seasons.

Summary of the invention

In order to overcome above-mentioned defective, the principle of the horizontal fire tube boiler of the utility model employing external combustion designs in conjunction with the structure and the handling characteristics of domestic burners.

The utility model is the manufacturing mode of traditional boiler one to be simplified resolve into pot body portion and body of heater two large divisions.The pot body portion is subdivided into four parts again: promptly upper and lower drum, flue, expansion tank.Each parts screw assembles an integral body.Offering a fire door again at the flue middle part can be for heating up water, and steamed rice is used.But not time spent gland sealing.Body of heater, pot body, flue periphery are provided with heat-insulation layer, prevent that heat scatters and disappears, and has attractive in appearance, durable advantage simultaneously again behind outer packaging.Be provided with two kinds of flues in the oven body part.Can select to use different coals for the user.The utility model beneficial effect is to have solved the shortcoming that causes furnace temperature not improve because of water-cooling wall, making (seeing accompanying drawing 7-13) behind horizontal water tube and the flue into has increased the endotherm area of pot body, and flue gas is discharged outdoor by chimney at the rear portion after expansion tank fully absorbs heat energy again.
