Description

From the blowing efficient economical coal stove

The utility model relates to a kind of improved coal furnace.

Stove and accessory is one of indispensable cooker in the daily life.Present stove and accessory is based on fire coal, and these coal-fired stove and accessorys mostly exist the thermal efficiency low, the defective of function dullness.

The purpose of this utility model provides a kind of from drying efficient economical coal stove, and this stove and accessory collection is from blowing, secondary air, cold water preheating, intensification, aerogenesis and one, not only quick combustion, firepower is violent, thermal efficiency height, and simultaneously heat supply water, steam, multiple functional, shorten the cooking time.

Taked following technical scheme for realizing the purpose of this utility model:

Make a kind of from drying efficient economical coal stove, this Energy-saving coal stove contains a body of heater, body of heater is built-in with the metal flue, be equipped with cold water preheating water bag, hot water bag and gas bag at furnace outer wall, and make it continuous, be filled with insulation material between flue and the body of heater with pipeline, be connected with between gas bag and the fire bars from the blowing-out gas pipe, be equipped with hot water jacket at the body of heater top, the bottom is provided with the storage slag bucket, makes from drying efficient economical coal stove.

The utility model only is provided with cold water preheating water bag, hot water bag and gas bag at furnace outer wall, and gas bag and fire bars used from the blowing-out gas pipe links to each other, and be placed with hot water jacket and get final product on body of heater, thereby the utility model is very easy to realize.

Utilize the utility model to do cooking, can carry out cooking simultaneously, steamed rice, also simultaneously heat supply water and steam are saved the cooking time, the energy utilization rate height.

Advance one below in conjunction with accompanying drawing and do not describe technical characterictic of the present utility model in detail.

The broken section structural representation of the embodiment that accompanying drawing, the utility model are preferentially selected for use.

As shown in drawings, 1 among the figure is body of heater, is installed with two hollow fire bars 2 in body of heater 1, is equipped with flue 3 above the hollow fire bars 2 in body of heater 1, and flue 3 is the metal flue.The inside of flue 3 is burner hearth, and the wind hole 4 on the hollow fire bars 2 is engraved in the burner hearth.Outer wall at flue 3 is fixed with cold water preheating water bag 5, hot water bag 6 and gas bag 7, and cold water preheating water bag 5 is linked to each other with hot water bag 6 by water pipe (does not draw at the flue back side), and hot water bag 6 is linked to each other with gas bag 7 by pipeline 8 and valve thereof again.Also be connected to the water inlet pipe 9 of band valve and the outlet pipe 10 of band valve on cold water preheating water bag 5, also be connected with the hot-water line 11 of band valve on hot water bag 6, the steam pipe 12 that contains valve communicates with gas bag 7; The end from blowing-out gas pipe 13 that contains control valve is connected in gas bag 7, its other end communicates with the cavity of hollow fire bars 2; On gas bag 7, also be provided with safety valve 21, be used to prevent that air pressure is too high has an accident.Secondary wind inleting tube 14 places the outer wall of flue 3, communicates in one end and body of heater 1 bottom, and the other end communicates with the exhaust vent 15 on body of heater 1 top, also is filled with insulation material 16 and is used to preserve moisture between body of heater 1 and flue 3.On body of heater 1, also be placed with hot water jacket 17, hot water jacket 17 is the ring-type hollow structure, is connected with the water pipe 18 and 19 that contains valve respectively on the both sides of hot water jacket 17, the bottom of body of heater 1 is provided with storage slag bucket 20.

The utility model is in practicality, except stove can normally burn, fry, after entering water preheat in the cold water preheating bag 5 by water inlet pipe 9, enter hot water bag 6 through water pipe and heat once more, the gas that becomes steam after the heating enters gas bag 7 through pipeline 8, opens the valve on blowing-out gas pipe 13, steam in the steam bag 7 can enter in the hollow fire bars 2, and discharge from the wind hole 4 of hollow body of heater bar 2, send combustion-supporting high damp steam to for burner hearth, increase very hot oven power.Be connected outlet pipe 10 on the cold water preheating water bag 5, be connected in the hot-water line 11 on the hot water bag 6 and be connected in hot water or the steam that steam pipe 12 on the gas bag 7 can provide different water temperatures, use in order to his; Place the hot water jacket 17 of body of heater 1 upper end, absorb the waste heat that fire door is done cooking, after the heating of the water in it, also can outwards provide hot water; One end of secondary wind inleting tube 14 communicates with the space of storage slag bucket, and the other end communicates with exhaust vent 15 above the burner hearth; Secondary wind inleting tube 14 places the outer wall of flue 3, and it is discharged from exhaust vent 15 after with the fresh air preheating, can be combustion-supporting, and make flame more prosperous, combustion water is more abundant, reduces the discharging of carbon monoxide or carbon dichloride; Be filled in the material which can retain moisture 16 between body of heater 1 and the flue 3, heat is distributed as far as possible less, improve the thermal efficiency, thereby realized the purpose of this utility model.
