Abstract

The utility model relates to an energy-saving and environment-friendly multifunctional furnace for heating and cooking, solving the problems of high energy consumption, low thermal efficiency, high running cost and less function of a traditional civilian-use cooking and heating furnace. The energy-saving and environment-friendly multifunctional furnace for heating and cooking is provided with a base, and a hot water boiler is arranged at the upper part of the base. The energy-saving and environment-friendly multifunctional furnace for heating and cooking is characterized in that a heating combustion chamber is arranged on the base; a cylindrical pot is installed on the heating combustion chamber and the central position of the hot water boiler; a continued burning chamber is formed by the hot water boiler, the heating combustion chamber and the cylindrical pot; and burning combustible material and unburned combustible material can be continuously burnt in the continued burning chamber and can perform heat exchange with the heated surface of the hot water boiler. The utility model has the advantages that the heating combustion chamber is arranged at the middle of the furnace so that burning coal does not contact with the water cooling wall of the hot water boiler directly in burning, the burning condition is good without baking coal, and the combustible material can be sufficiently utilized; the continued burning chamber is formed between the hot water boiler and the cylindrical pot, smoke and fire perform heat exchange with the heated surface of the hot water boiler with a turbulence state, thereby the heat resistance of a laminar flow boundary layer of the heated surface of the hot water boiler is reduced, the coefficients of heat transfer of convection and radiation are remarkably improved, and the thermal efficiency is improved.

Description

Energy-conserving and environment-protective functions of heating and cooking multipurpose furnace

Technical field

The utility model belongs to a kind of stove and accessory, particularly a kind of energy-conserving and environment-protective functions of heating and cooking multipurpose furnace.

Background technology

Domestic cooking heat supply stove of the prior art has many kinds, and wherein most typical is water-jacket typ cooking heating dual-purpose stove.Water-jacket typ cooking heating dual-purpose stove mainly is made of water jacket, fire bars, fire door, stove circle etc.It mainly adopts coal to act as a fuel, and coal burns on fire bars, with the water in water jacket heating, is used for heating, is used for cooking above the stove, but stove fire and the bottom of a pan be apart from far away, cooking and cook very slow.The problem that tradition domestic cooking heat supply stove exists also has, and fuel burns in burner hearth, and fire coal 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, the coefficient of heat transfer is little, the available energy loss is big, the heating surface area and the heating area of stove are little, and the thermal efficiency is low, are not suitable for burning low calorie fuels, the operating cost height, poisonous, harmful substance in the flue gas and CO ₂, the dust content height, air pollution is serious, the function of stove is few, applicable surface is narrow.

Summary of the invention

The technical problems to be solved in the utility model is, overcome the problem that energy consumption height, the thermal efficiency are low, operating cost is high, function is few that existing domestic cooking 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, operating cost is low energy-conserving and environment-protective functions of heating and cooking multipurpose furnace.

The utility model has a base, a hot-water boiler is arranged at base top, its special character is, a heating combustion chamber is arranged on base, on the heating combustion chamber, the center of hot-water boiler is equipped with the tubular pot, constitute the afterflame chamber between hot-water boiler and heating combustion chamber and the tubular pot, make and burn and unburned combustible burns away in the afterflame chamber, and carry out heat exchange with the heating surface of hot-water boiler.

Described heating combustion chamber is made of steel drum, fire proofed wood barrel and fire bars, on the wall of heating combustion chamber several air vents is arranged.

Secondary wind inleting tube is housed on base, makes air enter the afterflame chamber, combustion-supporting to unburned combustible in the afterflame chamber.

On the top of hot-water boiler the cooking combustion chamber is housed, the cooking combustion chamber is made of steel drum, fire proofed wood barrel and fire bars, and several air vents are arranged on the wall of cooking combustion chamber.

Advantage of the present utility model is:

1, heating combustion chamber and cooking combustion chamber are arranged on the centre of stove, directly do not contact with the water-cooling wall of hot-water boiler during fired coal combustion, and burning condition is good, do not bake charcoal, the combustible burning utilizes fully, the fire box temperature height, radiation coefficient is big, water quick heating, leaving water temperature height.

2, constitute the afterflame chamber between hot-water boiler and heating combustion chamber and the tubular pot, because the high temperature pyrotechnics at burner hearth center is squeezed the periphery of pot by the tubular pot, make the pyrotechnics heat flow density heighten, and in uphill process, wash away the heating surface of hot-water boiler, and carry out convection current and radiation heat transfer 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, convection current and radiation heat transfer coefficient have been significantly improved, improved the thermal efficiency, in addition, can boil water in the tubular pot in the time of heating, stew or steamed rice, the heating cost reduces greatly.

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, on the top of stove the cooking combustion chamber is set, can be used for cooking and cook, and flame is near from the bottom of a pan, cooking and cook soon, cost is low, is particularly suitable for small-sized administration, enterprises and institutions and civilian.

5, the fire bars of heating combustion chamber is turning, and aphlogistic bulk spoil is turning in following grey thorax.

6, body of heater is little, and floor space and space are little, and production cost is low, and heating area is big.
