The specific embodiment

Further illustrate example structure and the operation principle of the civilian firewood-saving and coal-saving multipurpose furnace of the utility model below in conjunction with accompanying drawing.

The structure of civilian firewood-saving and coal-saving multipurpose furnace is as Fig. 1, and Fig. 1 means, bottom is body of heater, and top is the material storing box as gas producer.Body of heater is provided with burner hearth 4, movable furnace grate 2 and charge door 3, and burner hearth 4 tops are front fire door.Movable furnace grate 2 belows are ash accumulating chamber 1, and this is also the air inlet of a combustion air; Burner hearth 4 first halves extend to gasification combustion chamber 13 to the right, and gasification combustion chamber 13 is provided with logical a heatable brick bed outlet flue 15; The top cooking mouth 12 of gasification combustion chamber 13 is heated up water and is cooked for a pot.Body of heater is provided with secondary combustion-supporting airduct 19, the lower end air inlet of this secondary combustion-supporting airduct 19 machine (in figure, blower fan does not draw) of giving a dinner for a visitor from afar, and the upper end air outlet is to be positioned at the air-out groove 17 that burner hearth and gasification combustion chamber connect position.Furnace body outer wall is provided with water jacket 16, and water jacket 16 is provided with cooling water inlet 18 and hot water outlet 14.

Referring to Fig. 1 and Fig. 2, material storing box 10 is shelved on the front fire door of burner hearth 4 tops, and material storing box 10 lower ends are provided with the fire grate 5 communicated with burner hearth.The bottom of material storing box 10 is provided with chuck 6, and the skin of chuck 6 is provided with water supplement port 7 and air intlet 9; Air intlet 9 is equipped with adjustable catch 9-1(referring to Fig. 3, and the large I of air intlet has a lot of regulative modes, and Fig. 3 mode is one of them), it can regulate the air capacity that enters chuck 6; Air-flow aperture 8 is opened in the bottom of chuck 6 internal layers, along the perisporium circumferential arrangement by material storing box 10, becomes 2 rows.

In this example, the diameter of material storing box 10 is 23~28cm, is highly 50cm, and chuck 6 is located at the Lower Half of material storing box 10, and the chuck internal layer is provided with two exhaust stream apertures 8, and end row's air-flow aperture 8 is the 8cm left and right with the distance of material storing box 10 bottoms; Each air-flow hole diameter is 1 cm, and arranging of water supplement port 7 is highly 7 cm.

Before the work of this combustion furnace, first material storing box 10 is placed in by stove, opens case lid 11, in material storing box 10, fill it up with living beings bulk cargo (i.e. the stalk through being cut into segment or fragment, Chai He etc.), close case lid 11 stand-by; From body of heater charge door 3 or fire door add coal or bavin in burner hearth 4, light.After burner hearth 4 internal combustion are more stable, material storing box 10 is positioned on front fire door 12, produce gradually dense flue gas.Adjust the air inflow that passes into chuck 6 from air intlet 9 by adjustable catch 9-1.The high temperature flare that material storing box 10 bottoms are produced by burner hearth 4 simultaneously heats, and makes the living beings bulk cargo be heated carbonization in the environment of material storing box 10 interior relatively hypoxias.When the biomass fuel in material storing box 10 starts to produce carbonization, the interior disposable water (water level is lower than end row's the residing height of air-flow aperture 8) that adds 200 mL left and right of 10 chuck 6 from water supplement port 7 to material storing box, the water generation steam that is heated, steam and the air entered in chuck 6 all enter in material storing box 10 by the air intake aperture 8 of chuck 6 internal layers, with the carbon generation redox reaction of gasification of biomass gas and generation, produce the fuel gas such as hydrogen, methane, carbon monoxide.These fuel gas mix with the flue gas that burner hearth 4 fuel combustion produce gradually, high-temperature flue gas fully burns by air-out groove 17 oxygen supplys, thereby produce a large amount of high-temperature flue gas, can carry out cooking at cooking mouth 12, lead to a heatable brick bed heating by logical a heatable brick bed outlet flue 15 simultaneously, water in water jacket 16 absorbs the body of heater waste heat, produces hot water, for heating.The ashes of fuel are settled down to ash accumulating chamber 1, are convenient to deashing.

The high temperature that coal combustion produces can be by biomass fuel gasifying, the fuel gas that gasification of biomass produces adds to again burner hearth, guarantee that coal combustion is more complete, thereby the shortcoming in the time of can having made up coal and this two kinds of fuel combustions of living beings reaches the purpose of clean burning, fuel saving.

Through test, adopt the normal domestic coal stove, singlely take coal during as fuel, consume the 1.5kg coal, sustainable burning 40 minutes; During with biomass fuel, consume biomass fuel 3kg, sustainable burning 30 minutes as single.The two addition, 1.5kg coal and 3kg biomass fuel sustained combustion time are 70 minutes altogether.

And the civilian firewood-saving and coal-saving multipurpose furnace of employing the utility model, use the 1.5kg fire coal in burner hearth, add the 3kg biomass fuel in material storing box simultaneously, sustainable smooth combustion 2.5 hours (150 minutes), visible the utility model is as domestic stove, with traditional stove and accessory, compare, fuel availability greatly improves.
