Description

The combustion stablized warm Multipurpose coal stove of cooking a meal of heat transfer vortex radiation

The utility model relates to coal stove, is the combustion stablized warm Multipurpose coal stove of cooking a meal of a kind of heat transfer vortex radiation.

At present, the coal stove kind of selling on the market is a lot, and the great majority warm dual-purpose coal stove structure of cooking a meal is basic identical, all form, be divided into by the water jacket form by stove and water jacket two parts: 1) simple water-jacket typ, water jacket is enclosed within outside the combustion chamber, this type of furnace heat exchange is insufficient, and heat exchange efficiency hangs down the coal consumption height; 2) hearth water sleeve adds the flue water-jacket typ, and two water jackets are connected difficulty, and the after funnel water jacket of banking up a fire does not play heat-absorbing action, and plays the heat release cooling effect; 3) fin water-jacket typ, by suppressing the heat exchange of ignition system high temperature, heat exchange efficiency height, but operation inconvenience, cooking has poor, and the warm contradiction of easily cooking a meal influences each other.

The purpose of this utility model provides the combustion stablized warm Multipurpose coal stove of cooking a meal of a kind of heat transfer vortex radiation, and is insufficient to solve simple water-jacket typ heat exchange, and heat exchange efficiency hangs down the coal consumption height; Burner hearth adds chimney water-jacket typ two water jackets and is connected difficulty, and the after funnel water jacket of banking up a fire does not play heat-absorbing action, and plays the heat release cooling effect; Fin water-jacket typ cooking poor performance, the warm contradiction of the cooking a meal problem that influences each other.

The purpose of this utility model is achieved in that according to heat transfer, radiation theory, optimal design forms on above-mentioned type of furnace basis, this stove is made up of stove and water jacket two parts, stove is by fire door, the stove leg, furnace shell, heat transfer layer, combustion chamber, chimney, the stove circle, furnace chamber is formed, water jacket is divided into 3 parts, outside heat transfer layer, be with hot water jacket, there is water inlet pipe the water jacket bottom, above by being communicated with the fin water jacket communicating pipe, at funnel casing chimney water sleeve is arranged,, be provided with outlet pipe in the chimney water sleeve upper end by being communicated with communicating pipe with the fin water jacket, be provided with air heat-insulation layer between hot water jacket and furnace shell, the chimney end opening is positioned at fin water jacket downside.

Fin water jacket downside is evenly equipped with at least 3 communicating pipe, has 4 curved fins at least, the high 22--26mm of fin.

Principle: cold water, is entered chimney water sleeve then and absorbs heat once more through the heat exchange of fin water jacket high temperature by the hot water jacket preheating, and high-temperature water can be for having a bath, warming oneself; Coal-fired hot flame gas is come out directly to carry out cooking by combustion chamber, if build the stove circle, flame gas rotates into chimney at the suction lower edge of chimney fin water jacket downside fin, through chimney water sleeve heat exchange low-temperature flue gas emptying once more.

This utility model compared with prior art has the following advantages: it is abundant that 1) water jacket is divided into 3 part heat exchange, heat exchange efficiency height, province's coal; 2) be provided with the fin water jacket, water quick heating temperature height; 3) bank up a fire the back heat exchange property good, the heater temperature height is held time; 4) firepower is concentrated during the little cooking of heat transfer water jacket and fin water jacket spacing, and the cooking time is short; 5) function is many, but but bath, heating are washed in the cooking heat supply.

Be described further below in conjunction with accompanying drawing:
