Abstract

The utility model discloses a double-hearth reverse-burning type energy-saving stove, which includes an inner hearth (13), an outer hearth (14), an inner stove sleeve (15), an outer stove sleeve (16), as well as a top center plate (5) and a bottom center plate (4) which are installed in the inner stove sleeve (15), wherein fuel gas enters the outer stove sleeve (15) to be communicated with the inner stove sleeve (16) through the lower part of the stove body, is ignited through an electronic ignition device (3), and then blown into the inner stove sleeve (15) by a blower (17) from a lower opening of an outer stove plate, and enters a combustion chamber (20) from through holes on the periphery at the upper part of the inner stove sleeve (15); residual heat air and heat smoke of the outer hearth (14) enter a hot water tank (9) through a flue duct (7) of the outer hearth (14), so as to heat the hot water tank (9); and hot air and flue dust are exhausted from the flue duct. The temperature of the exhausted smoke and that of the hot water are basically identical, thereby achieving the purposes of complete utilization of energy source and energy conservation.

Description

Twin furnace counter-burning type energy-saving stove

Technical field

The utility model relates to a kind of twin furnace counter-burning type energy-saving stove, especially it reaches the purpose that makes full use of the energy by inside and outside twin furnace and anti-mode of burning, and utilize the waste heat after the burning when chimney is discharged fume, to come processing hot water through boiler, make the energy and heat reach sufficient utilization.

Background technology

Cooking stove is the facility of huge numbers of families, restaurant, the requisite cooking of cooking in restaurant.Restaurant, restaurant, home-use kitchen range mostly are that naked light exposes both at home and abroad at present, disposable enamelware pot is extracted emptying out by smoke exhaust ventilator, its thermal efficiency is too low, to energy fuel, combustion gas is a waste, novel cooking stove is also arranged, Yi Bian cook on the market, utilize the waste heat manufacture hot water on one side, weak points such as but structure is unreasonable, and combustion gas is fully burning not, and heat utilization efficiency is too low.

Summary of the invention

The purpose of this utility model just provides a kind of twin furnace counter-burning type energy-saving stove that has, and combustion gas fully reaches energy-conservation purpose through inside and outside burner hearth and anti-burning mode, improves the utilization rate of heat energy.

Provide a kind of twin furnace counter-burning type energy-saving stove for reaching above-mentioned purpose, it is by internal furnace, outer burner hearth, interior boiler clothing, outer boiler clothing and body center plate and center bearing are formed, combustion gas enters outer boiler clothing by the stove bottom, boiler clothing end opening in connecting, after ignition is lighted, be blown into pressure wind at air blast by outer stove stone or metal plate for standing a stove on as a precaution against fire end opening, enter interior boiler clothing top through hole all around by outer boiler clothing, enter the combustion chamber, with by the combustion gas of interior boiler clothing bottom ejection through center bearing, enter body center plate and enter the combustion chamber mixing, oxygenation is fully burnt, the back is by counter burning into into outer burner hearth in the multidigit hole around the internal furnace upper end, and burner hearth fully heats the flue of back waste heat by outer burner hearth outside, and all the other hot radical capital and interest use up by flue upper end emptying after boiler makes full use of.The cigarette temperature of its discharge equates substantially with the temperature of boiler, reaches to make full use of the energy and purpose of energy saving, is equipped with heat-insulation layer around reaching energy-conservation burner hearth outside, is incubated with soft materials such as fire-resistant asbestos.
