Abstract

A domestic smokeless warming furnace is characterized in that the furnace adopts the principle of combustion in both the front and the rear sides and comprises two furnace tanks and two grate bars, and a curved fireproof arch is arranged inside a primary combustion chamber. Coal bricks are fed into the primary combustion chamber for combustion from a coal feeding and oxygen adjusting door, and the combusting flame and non-burnt out burning coal bricks continue combusting in a secondary combustion chamber. A mixed flame obtained after combusting in the secondary combustion chamber is introduced into a smoke abatement and dust fall settlement chamber from flues on the two sides in the furnace, directly rushes to the bottom of a baking chamber arranged at the upper end of the furnace body, and is discharged into the air from a smoke outlet port of the furnace body through vertical and transverse heat radiating chimneys additionally arranged indoor and outdoor. The domestic smokeless warming furnace has the advantages of simple structure, high practicability, few or no smoke discharge, high heat efficiency, low energy consumption, and environmental friendliness; and is ideal equipment for independently warming in rural households.

Description

The family expenses smokeless heating furnace

Technical field

The utility model relates to a kind of coal-fired domestic heating stove, specifically a kind of energy-conserving and environment-protective family expenses smokeless heating furnace.

Background technology

Present various coal-fired domestic heating stove is though various places pattern difference all is with the family's heating and the usefulness of cooking, it is a heating system independently, being a kind of dry combustion method stove, by body of heater and the smoke evacuation tube heat radiation heating that is connected body of heater, is town and country, various places rural households the most general the most common heating systems.But all the ubiquity burning is insufficient, and the thermal efficiency is low, the problem that smoke density is big.Because accumulating every several days of chimney coal ash must be won chimney cleaning coal ash, not only waste energy but also increase labour intensity, therefore need to propose better solution.

Summary of the invention

The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of environment-friendly household smokeless heating furnace.

The utility model is to realize with following technical scheme: this sufficient combustion thermal efficiency height, and can bakery product, the burning smoke coal of heating food and smokeless environmental protection domestic heating stove, it comprises: body of heater, curved surface refractory arch, primary zone and fire grate, secondary combustion chamber and fire grate, side flue, falling dust room, coal are transferred the oxygen door, are observed clean-out door, baking chamber, ashes drawer.

It is characterized in that: be provided with the curved surface refractory arch in the affiliated body of heater, be attached on the primary combustion locular wall, fire grate lower end, primary zone is provided with secondary combustion chamber and fire grate, the different side flue of lower section on both sides are provided with in body of heater, both sides flue meet is provided with smoke elimination falling dust room, be provided with baking chamber in the body of heater upper end, be used for bakery product, heating food, be provided with ashes drawer and damper in secondary combustion chamber fire grate lower end.

The further significant effect of the utility model is embodied in:

1, the setting of the utility model primary zone curved surface refractory arch transfers the adjusting of oxygen door to supply with the indoor needed oxygen of primary combustion by coal, and the coal cinder that makes it to add is fully burned.

2, the utility model be located at secondary combustion chamber under primary zone's fire grate with the unburnt red charcoal in primary zone and the flame that returns down carry out second-time burning, secondary combustion chamber obtains an amount of oxygen from the air door on the ashes drawer, carry out secondary and fully burn, making it slag does not have burning value again.

3, the mixed flame of primary combustion and second-time burning merges in smoke elimination falling dust room via flue upper end in both sides in the body of heater, and flings baking chamber bottom, body of heater upper end, is discharged by chimney then.

The utlity model has following some:

1, no black smoke discharging, lingemann blackness＜1 reaches national environmental standard.

2, sufficient combustion, slag is few, economizes on coal more than 30%.

3, fire-sealing time is long, can automatic combustion after banking up a fire.

4, heat dissipation capacity is big, and heat makes full use of, but also bakery product heats food.

Fig. 2 is a front of the present utility model sectional structure schematic diagram;

Fig. 3 is a side of the present utility model sectional structure schematic diagram.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to accompanying drawing, the family expenses smokeless heating furnace is provided with body of heater 1, baking chamber 4, transfers oxygen firing door 6, primary zone 7 and upper furnace grate 8, secondary combustion chamber 9 and lower fire grate 10, the unburnt red charcoal in primary zone is fallen on the fire grate of secondary combustion chamber 10 flames that return under with a combustion chamber, supply with oxygen at secondary combustion chamber by ashes drawer damper 14, carry out the burning second time, mixed flame enters the bottom that smoke elimination falling dust room 12 upwards flings baking chamber 4 through side flue 11, enter the chimney outlet behind the baking in heat chamber, the indoor and outdoor through adding chimney anyhow enters atmosphere.

Present embodiment is through on probation, and effect is good especially, economizes on coal more than 30% than existing various domestic heating stove, sufficient combustion, lime-ash reduces, without energy savings, and smoke density is less than 1 lingemann blackness, and no coal dust accumulates in the chimney, and every index all meets or exceeds related standards.
