Abstract

A heating furnace with high thermal efficiency belongs to the technology field of the civil furnace or cookware, and is used for improving the thermal efficiency of the furnace. The technical proposal is that the heating furnace comprises a furnace body, a furnace chamber, a fire grate, an insulating layer and a flue 4, wherein the furnace body is interlayer-shaped, and forms a furnace body water jacket; the furnace chamber is positioned in the center part of the furnace body, the insulating layer is arranged in the furnace chamber, and the fire grate is arranged at the lower part of the insulating layer; after the heating furnace is improved, a ring-shaped water jacket is added at the middle and the upper parts of the insulating layer, and is communicated with the furnace body water jacket. By adding the ring-shaped water jacket and a fire hole ring, the heating furnace adds two more times of heating and improves the heat exchange performance of the furnace; by adding a hot water tank used for absorbing the waste heat of the flue gas in the position of a chimney, the thermal energy loss is further reduced. According to the test, the thermal efficiency thereof can be increased from the originally 40%-50% to 65%-75%. The heating furnace is suitable for use by the heating and bathing furnaces in residences, hotels, schools, hospitals, etc., and can also be used as the dual-purpose furnace for heating and cooking.

Description

Heating stove with high thermal efficiency

Technical field

The utility model relates to a kind of energy-saving heating stove and accessory, belongs to domestic burners or kitchen range technical field.

Background technology

Existing civil heating furnace structure, burner hearth generally are designed to directly communicate with flue, and a large amount of pyrotechnic gas are directly discharged from flue, and heat runs off serious.As water jacket and the hot-water line that thermoreceptor in the heating system uses, be arranged on the burner hearth middle and upper part usually and directly contact, owing to the cause that wherein is filled with recirculated water with stove fire, temperature is lower, because it directly surrounds burner hearth, also causes stove fire not prosperous, furnace temperature reduces, and the whole temperature raising of stove and accessory is slower.In addition, because stove and accessory must cover the stove fire lid when heating, make the stove fire burning directly rush at the stove fire lid, heat by flue and stove fire lid to around distribute, heat energy dissipation is very fast, waste heat can not make full use of, for improving furnace temperature, have to add fire coal again, cause waste of fuel, reduce the thermal efficiency of stove and accessory.Cooking, when heating up water, also having same problem.

Summary of the invention

The utility model is to overcome the deficiency of existing Heating stove, provides a kind of thermal efficiency height, the energy-saving heating stove of energy savings.

The technical scheme that addresses the above problem is:

A kind of heating stove with high thermal efficiency, it comprises body of heater, burner hearth, fire grate, heat-insulation layer and flue, described body of heater is arranged to sandwich-like, constituted furnace water jacket by it, described burner hearth is positioned at the body of heater centre, is provided with heat-insulation layer in the burner hearth, and the heat-insulation layer bottom is a fire grate, after the improvement, set up ring-shaped water jacket, ring-shaped water jacket and furnace water jacket in the middle and upper part of heat-insulation layer and be connected.

Above-mentioned heating stove with high thermal efficiency is provided with first converter mouth ring and second converter mouth ring above fire door, converter mouth ring be arranged to the water jacket shape, and and furnace water jacket communicate, be provided with at interval between two converter mouth rings, chamber of Gou Chenging and chimney communicate thus.

Above-mentioned heating stove with high thermal efficiency is provided with a grade pyrosphere between the described fire door and second converter mouth ring, described shelves pyrosphere is a semicircle shape.

Above-mentioned heating stove with high thermal efficiency, the chimney periphery above body of heater is provided with self-contained water tank, and self-contained water tank is provided with water inlet and delivery port.

The utility model is to overcome the existing low defective of the heating stove thermal efficiency, increases the dress ring-shaped water jacket in the periphery of stove and accessory heat-insulation layer, forms a thermoreceptor of stove and accessory; Two converter mouth rings of interlayer are set above fire door, form the secondary thermoreceptor of stove and accessory, twice thermoreceptor is communicated with furnace water jacket, thereby improved the heat exchange performance of stove and accessory.Set up the boiler that is used to absorb fume afterheat at the chimney place, thereby further reduced heat energy loss.

The utility model adopts the heat energy of multiple heat absorbing mode and makes full use stove and accessory, have rational in infrastructure, temperature fluctuation is little, easy to use, Remarkable Energy Saving advantage.After tested, its thermal efficiency can bring up to 65%～75% by original 40%～50%.Suitable heating as dwelling house, hotel, school, hospital etc., bathing stove and accessory use, and also can be used as the dual-purpose stove and accessory of heating-cooking.

Description of drawings

Fig. 1 is the profile of the utility model front view;

Mark is as follows among the figure: body of heater 1, fire grate 2, support 3, flue 4, firestopping ring 5, ring-shaped water jacket 6, self-contained water tank 7, shoot door 8, second converter mouth ring 9, heat-insulation layer 10, stove fire lid 11, first converter mouth ring 12, fire door 13, water inlet 14, delivery port 15.

The specific embodiment

Referring to accompanying drawing 1, the utility model is the improvement on the Heating stove basis, and it comprises body of heater 1, fire grate 2, heat-insulation layer 10, ring-shaped water jacket 6, last lower deashing hole and the flue 4 that has water jacket.Fixing heat-insulation layer 10 on the support 3 of body of heater inner chamber bottom, heat-insulation layer 10 is positioned at the burner hearth centre, and fire grate 2 is below the burner hearth bottom support.Heat-insulation layer adopts refractory material, and the periphery, middle and upper part of heat-insulation layer is a ring-shaped water jacket 6, fills heat transfer medium (water) in the water jacket.The top of fire door is provided with two intercalated water sleeves, forms first converter mouth ring 12 and second converter mouth ring 9.Firestopping ring 5 in burner hearth and the setting of flue place can be regulated, thereby obtains different aisle spares, reaches the purpose of regulating pyrotechnics dissipation.Stove and accessory has rear-mounted flue interface, further connection level of flue interface or the slightly acclivitous self-contained water tank 7 that is used to absorb fume afterheat.

Form ring cavity between the ring-shaped water jacket 6 of heat-insulation layer outside and the body of heater 1, stove fire rises and meets firestopping ring 5 back wraparounds, by ring cavity ring-shaped water jacket and furnace water jacket are heated, flue gas is discharged by oblique flue then, heating system and self-contained water tank to annular smoke flue heats simultaneously, makes heat be able to fullest and effectively utilization.

The utility model is added a cover the stove fire lid on body of heater, bell is a disc, and it forms stove and accessory and suppresses fiery effect, and the whole temperature raising of body of heater is very fast.
