Abstract

The invention relates to a multipurpose high efficient energy-saving environmental-friendly stove with functions of heating and cooking, which solves the problems of high energy consumption, low heating efficiency and few functions of the existing heating-supply stove. The stove is provided with a base on which a water boiler is arranged; the stove is characterized in that a lower combustion chamber is arranged in the base, a lower firebar is installed in the lower combustion chamber, a heat-collecting cylinder is arranged on the lower combustion chamber and in the center of the water boiler, the upper part of the heat-collecting cylinder is provided with an upper firebar, an upper combustion chamber is formed on the heat collecting cylinder and the water boiler, a gap is left between the heat-collecting cylinder and the water boiler so as to form a combustion-continuing chamber so as to lead combustible substance burning or not being burnt to enter the combustion-continuing chamber for later burning, and the combustion-continuing chamber can carry out heat exchange with the water boiler simultaneously. The stove has the advantages that the combustion chamber has no water cooled wall, the combustible substance are fully utilized, convection heat transfer coefficient and radiation heat transfer coefficient are large, heat exchange resistance is small, heating efficiency is high, the generation and discharge amount of thermal NOx are obviously reduced, thus having wide application range and low production cost.

Description

Multipurpose high efficient energy-saving environmental-friendly stove with functions of heating and cooking

Technical field

The invention belongs to a kind of stove and accessory, particularly a kind of multipurpose high efficient energy-saving environmental-friendly stove with functions of heating and cooking.

Background technology

Civilian heat supply stove of the prior art has many kinds, and wherein most typical is the water-jacket typ heat supply stove.The water-jacket typ heat supply stove mainly is made of water jacket, fire bars, fire door, ash door etc.It mainly adopts coal to act as a fuel, and burns on fire bars, and the water in the water jacket is heated.The heat supply stove that has also is provided with the endothermic tube that communicates with water jacket in order to improve the thermal efficiency in burner hearth.The subject matter that the civilian heat supply stove of above-mentioned tradition exists is, fuel burns in burner hearth, coal-firedly directly contacts with water-cooling wall, coal easily bakes charcoal, and the chemical energy in the fuel can not completing combustion, and heat loss is big, the energy consumption height, fire box temperature is low, and comburant and heating surface radiation heat transfer coefficient are little.When pyrotechnics and heating surface heat convection, the laminar boundary layer thermal resistance that the flue gas that wall-cooling surface is detained forms is big, and the coefficient of heat transfer is little, the available energy loss is big, and the heating surface area and the heating area of stove are little, and the thermal efficiency is low, poisonous, harmful substance in the flue gas and dust content height, air pollution is serious.The function of stove is few, and applicable surface is narrow.

Chinese patent ZL01241638.X discloses a kind of " energy-saving multi-purpose stove ", it mainly comprises furnace shell and heat gathering tube, heat gathering tube is made of skeleton, solid material and water jacket, water jacket is made of upper and lower water tank and water courage, on heat gathering tube, also have several through holes, between heat gathering tube and furnace shell, constitute the afterflame chamber as little burner hearth.The subject matter that this energy-saving multi-purpose stove exists is, the water courage is included in the solid material, therefore, the temperature of heat gathering tube is difficult to improve, the port thorax is guided to the afterflame chamber of heat gathering tube outside with heat energy, but the indoor not heating part of afterflame makes casing temperature raise on the contrary, burning and the loss of heat transfer available energy increase, and have caused the waste of heat energy.In addition, the heating surface area of this energy-saving multi-purpose stove is little, and convection current and radiation heat transfer coefficient are little, and the thermal efficiency is low, and it is insufficient to burn, and poisonous, harmful substance and dust content in the flue gas are big.The operating cost height, function is few, and use face is narrow.

Summary of the invention

The technical problem to be solved in the present invention is, overcome the problem that energy consumption height, the thermal efficiency are low, function is few that existing civilian heat supply stove exists, provide that a kind of burning condition is good, fire box temperature is high, convection current and radiation heat transfer coefficient is big, function is many, the thermal efficiency is high multipurpose high efficient energy-saving environmental-friendly stove with functions of heating and cooking.

The present invention has a base, a hot-water boiler is arranged at base top, its special character is, lower combustion chamber is housed in base, fire bars down is housed in lower combustion chamber, on lower combustion chamber, the center of hot-water boiler is equipped with heat gathering tube, fire bars is equipped with on the top of heat gathering tube, top at heat gathering tube and hot-water boiler constitutes upper combustion chamber, leave the space between described heat gathering tube and the hot-water boiler, constitute the afterflame chamber, making and burning and unburnt combustible enters the afterflame chamber and burns away, and carry out heat exchange with the heating surface of hot-water boiler.

Bolster is equipped with at two ends at last fire bars and following fire bars respectively, and handle is housed on the bolster, constitutes convertible fire bars.

The invention has the advantages that:

1, at the center of hot-water boiler heat gathering tube is set, fire coal does not directly contact with the water-cooling wall of hot-water boiler, and the fired coal combustion condition is good, does not bake charcoal, the combustible burning utilizes fully, heat gathering tube temperature height, and the radiation heat transfer area is big, and radiation coefficient is big, the water quick heating, the leaving water temperature height, heating area is big.

2, leave the space between heat gathering tube and the hot-water boiler, constitute the afterflame chamber, and several pyrotechnics through holes are set on heat gathering tube, make pyrotechnics enter into the afterflame chamber, wash away the heating surface of hot-water boiler earlier, and carry out heat exchange with the heating surface of turbulent condition and hot-water boiler, then attenuate the laminar boundary layer thermal resistance of hot-water boiler heating surface, significantly improve convection transfer rate, reduced the available energy loss, improved the thermal efficiency.

3, the afterflame chamber forms the gravitational dust collection structure, and it is many that flue dust is trapped in the stove, and it is few to discharge out of the furnace, the afterflame chamber generation and the discharge capacity that has reduced heating power type NOx be set.

4, the scope of application is wide, when good coal burns on last fire bars, but cooking cook, when dant burns on following fire bars, can little fire burns, burning time is long, can be used for heating or bathing, operating cost is low, and multi-use is particularly suitable for small-sized industry and commerce, administration, enterprises and institutions and civilian.

5, upward fire bars and following fire bars are all turning, fuel on the last fire bars is the time spent not, can translate into down on the fire bars and use, fuel on the following fire bars is the time spent not, can turn down, take on the fire bars and use, cooking, heating, heat supply water are changed mutually, fast, economize bavin, save trouble, health, and fuel is selected face width.

6, manufacture craft is simple, and hot-water boiler, heat gathering tube and upper and lower fire bars are made separately, assembles easyly, and body of heater is little, and floor space is little, and material consumption is few, and production cost is low.
