Abstract

The utility model relates to a high-efficiency and energy-saving coal furnace. Its technical scheme is: it is composed of a furnace body, a furnace furnace, a furnace cover, a chimney, a coal ash outlet and a circulating water pipe. The ash leakage handle and the coal ash outlet are arranged under the furnace furnace, and a blower is arranged under the ash leakage handle. A combustion chamber with a tapered cavity structure formed between the furnace and the furnace cover, the combustion chamber communicates with the outer wall of the furnace body through a through hole to form an extended combustion chamber, and the open flame and soot in the furnace pass through The extended combustion chamber enters the chimney and is discharged, and the circulating water pipe passes through the extended combustion chamber. The beneficial effects of the utility model are: the time for the open flame and soot to stay in the furnace body is increased, and the open flame of the original furnace is prevented from being directly sucked into the chimney, thereby improving the combustion efficiency, effectively saving coal, and being suitable for use. It is widely used in household coal stoves and heating with radiators.

Description

Efficient economical coal stove

One, technical field:

The utility model relates to a kind of stove, particularly a kind of efficient economical coal stove that is used for heating system.

Two, background technology:

At present, coal stove and native heating installation have been widely used in the apparatus that residents such as town and country village warm oneself winter, yet, in order to make coal stove burning De Gengwang, the general method that adopts is to increase the chimney ground level, but has increased the consumption of coal simultaneously, causes people afford to adorn that soil warms up and with not rising.Another kind of way is to establish air blast in the bottom of body of heater, but tends to cause the situation of flying upward that the coal ash in the stove is blown everywhere, severe contamination indoor environment, brought harm to the user.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of and save fire coal, reduces user's expense expenditure, the efficient economical coal stove of minimizing coal ash pollution.

Its technical scheme is: by body of heater (10), flue (5), bell (11), chimney (9), coal ash outlet (4) and circulating water pipe (1) are formed, described flue (5) below is provided with Lou grey handle (7) and coal ash outlet (4), leak grey handle (7) below and be provided with air blast (3), the combustion chamber (13) of the conical cavity structure that forms between described flue (5) and the bell (11), be communicated with by through hole (14) between the outer wall of described combustion chamber (13) and body of heater (10), form expansion combustion chamber (12), naked light in the flue and coal smoke enter chimney (9) by expansion combustion chamber (12) and discharge, and circulating water pipe (1) is by described expansion combustion chamber (12).

Preferable technical scheme is: be provided with bellows (2) between grey handle of described leakage (7) and the air blast (3), the air outlet of bellows (2) stretches to the below of flue (5), and the air inlet of bellows (2) connects air blast (3).

The cavity that forms between the inwall of described bellows (2) and body of heater (10) is Dust Storage Room (15), and coal ash is discharged by coal ash outlet (4), and the inwall of described flue (5) is provided with one deck seat clay (6).

The beneficial effects of the utility model are: by the combustion chamber of the conical cavity structure that forms between flue and the bell, be communicated with by through hole between the outer wall of combustion chamber and body of heater, form the expansion combustion chamber, make naked light and coal smoke in the flue enter the chimney discharge by the expansion combustion chamber, thereby increased the time that naked light and coal smoke stop in body of heater, avoided the naked light of original stove directly to be drawn onto in the chimney, thereby improved efficiency of combustion, effectively saved fire coal, be applicable to multiple scopes such as household coal-stove and the heating of band radiator.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

Five, the specific embodiment:

In conjunction with the accompanying drawings, the utility model will be further described:

Its technical scheme is: by body of heater 10, flue 5, bell 11, chimney 9, coal ash outlet 4 and circulating water pipe 1 are formed, described flue 5 belows are provided with Lou grey handle 7 and coal ash outlet 4, leak grey handle 7 belows and be provided with air blast 3, the combustion chamber 13 of the conical cavity structure that forms between described flue 5 and the bell 11, be communicated with by through hole 14 between the outer wall of described combustion chamber 13 and body of heater 10, form expansion combustion chamber 12, the inwall of flue 5 is provided with one deck seat clay 6, heat-resisting effect is better, naked light in the flue and coal smoke enter chimney 9 by expansion combustion chamber 12 and discharge, thereby increased the time that naked light and coal smoke stop in body of heater, avoided the naked light of original stove directly to be drawn onto in the chimney, circulating water pipe 1 is by described expansion combustion chamber 12, like this, also increase heating surface area, improved heat exchange efficiency.

In addition, be provided with bellows 2 between grey handle 7 of described leakage and the air blast 3, the air outlet of bellows 2 stretches to the below of flue 5, the air inlet of bellows 2 connects air blast 3, one end of described air blast 3 is provided with wind speed control button 8, effectively controlled wind speed enters in the stove, and the cavity that forms between the inwall of described bellows 2 and body of heater 10 is a Dust Storage Room 15, and coal ash is discharged by coal ash outlet 4.

Both gone for the heating of independent household coal-stove, also gone for the heating of coal stove band radiator, just scope such as native heating installation.
