Description

Circular tube type energy-saving furnace

The utility model relates to solid-fuelled domestic burners, particularly a kind of circulation tube type energy-saving stove.

Present heating stove for civilian use tool, mostly be to adopt the traditional type stove and accessory, or in body of heater, add water jacket recirculated water heating, general maximum 3～5 radiators of also just being with, during heating with moulded coal, the diffusing coal burner hearth of packing into, by the natural air burning, burning insufficient, dust pollution environmental hazard health of human body under the last cigarette, and the heat energy utilization rate is low, has shortcomings such as the band radiator is few, for overcoming above-mentioned deficiency, the utility model designs a kind of circulation tube type energy-saving stove, the running of employing water circulating pump, water seal blower fan force to help the oxygen burning, and wet method is removed boiler ash sediment, reduce contamination by dust, this device has sufficient combustion, the burning out rate height of carbon, heat energy utilization rate height, and health, be with characteristics such as radiator is many.

The purpose of this utility model provides a kind of sufficient combustion, the wet circulation tube type energy-saving stove that removes boiler ash sediment of water seal.

The utility model is achieved in that thermal insulation layer in furnace shell, water jacket is equipped with in the thermal insulation layer inboard, and refractory lining is equipped with in the water jacket inboard.The place, bottom of furnace shell has furnace hearth plate, lay a fire grate on the furnace hearth plate with in the refractory lining, be welded with heat collector panel at the water jacket upper end, form burner hearth, it is first combustion chamber, the middle part of heat collector panel is provided with a round fire door, lay a nozzle on the fire door, nozzle is that round interior bottom side is a pyramid type, 8-10 little through hole arranged on the pyramid type side, the centre is the column type through hole, be welded with an annulus hydrosphere at the heat collector panel upper end, inboard around the annulus hydrosphere inside upper part is welded with 10-16 circulation pipe, the circulation pipe upper end communicates with the annulus hydrosphere, the circulation pipe lower end communicates with water jacket, circulation pipe is welded on the middle part of heat collector panel upper surface apart from annulus hydrosphere and fire door, top end is laid stove cover plate on the furnace shell, the stove circle, little bell, the left side that runs through the annulus hydrosphere in the furnace shell upper end is welded with a flue, forms second combustion chamber, the outside in furnace shell annulus hydrosphere left side central portion is welded with an outlet pipe, communicate with the annulus hydrosphere, at furnace shell, water jacket outside right-hand end down is welded with return pipe, communicate with water jacket, be welded with and the corresponding annulus water of furnace shell box at the furnace hearth plate lower end, diameter has the ash discharge cinder notch of a upper shed greater than upper end diameter at the bottom of the water box at water box one face down bonding, the corresponding air duct that is welded with furnace lining is arranged in the furnace hearth plate lower end, water box middle part is inserted in the air duct lower end, forms water seal, and air duct right side upper end is welded with an air inlet pipe that connects.

The operation principle of circulation tube type energy-saving stove is: during heating nozzle is taken out, (after nozzle is installed on the fire door, can make flame more concentrated, be used to boil water or the usefulness of cooked food.) will loose coal or moulded coal pack in first combustion chamber of burner hearth by fire door, force to help the oxygen burning by blower fan, stove fire heat radiation and high temperature furnace slag through burning fall into down in air duct and the water box, produce steam, through blower fan steam is sent into burner hearth and done the coal mixing semicoke reflection of slipping again, the burning of generation water-gas, being sprayed onto second combustion chamber from the heat collector panel fire door fully burns, and directly conduct many circulation pipes and the annulus hydrosphere of second combustion chamber, make the water firing rate fast, effect by circulation low speed water pump is imported in the radiator rapidly, because the last water mouth of a river is the opening running, circulation low speed water pump is connected on the return pipe, is not closed circulation, be no pressures cycle, do not have the trouble of blast.

Circulation tube type energy-saving stove of the present utility model, adopted the furnace bottom water seal, blower fan is forced oxygen supply, and produce the water-gas burning, reach quick combustion, the flame height, fully burn by second combustion chamber, circulation pipe conducts heat, thereby the heat energy utilization rate improves greatly, has made full use of heat energy, can be with radiator 20-30 sheet, also applicable to the heating of two floor rooms, heating area can reach 100-150 square metre, has energy-conservation, the health environment purification reduces pollution, easy to operate, and simple in structure, characteristics such as easily manufactured.
