Detailed description of the invention

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As depicted in figs. 1 and 2, the civilian gasification heating furnace of one of the present embodiment, it is characterized in that, comprise: body of heater 1, the aerogenesis storehouse 2 of combustion gas is produced for carbonization solid material, for the mixing bunker 8 of mixture of oxygen and combustion gas, first combustion chamber 4-1, second combustion chamber 4-2, 3rd combustion chamber 4-3 and and to light a fire switch 11, described aerogenesis storehouse 2 is anaerobic environment, described aerogenesis storehouse 2 surrounding is provided with cyclic water channel (for heat exchange and temperature control), described mixing bunker 8 is positioned at body of heater 1 bottom position place and is positioned at the below in aerogenesis storehouse 2, described aerogenesis storehouse 2 is connected with mixing bunker 8, described mixing bunker 8 is connected with the first combustion chamber 4-1, gaseous mixture in described mixing bunker 8 is successively through the first combustion chamber 4-1, second combustion chamber 4-2 and the 3rd combustion chamber 4-3 also burns in them, finally discharged by body of heater 1 top exhanst gas outlet 3, described body of heater 1 is provided with the oxygenation port 9 be connected with mixing bunker 8, described oxygenation port 9 place is provided with air-valve 10.Fuel gasification needs in anoxic, and temperature control (300-600 degree) when produces, and fuel realizes preheating through aerogenesis cabin, aerogenesis, reduction process.This civilian gasification heating furnace lights the fire in a stove before fuel is added by aerogenesis storehouse 2 to realize carbonization generation imflammable gas.Fuel is burning in aerogenesis storehouse 2, the surrounding in aerogenesis storehouse 2 is that water channel is around cooling, in storehouse bottom self-assembling formation (high temperature reduction layer), middle part (separating at high temperature layer), three, top (low-temperature prewarming layer) different temperatures layer, the combustion gas of generation enters mixing bunker 8 by furnace bottom position.

Preferably, the surrounding place of described first combustion chamber 4-1, the second combustion chamber 4-2 and the 3rd combustion chamber 4-3 is provided with the cyclic water channel for heat exchange.

Preferably, also comprise power switch 12, it is arranged between the first combustion chamber 4-1 and aerogenesis storehouse 2, can change fuel gas flow path by power switch 12, thus regulates combustion power.

Preferably, the second connected entrance 7-2 that the first connected entrance 7-1 that described 3rd combustion chamber 4-3 is connected with the second combustion chamber 4-2 is connected with the first combustion chamber 4-1 with the second combustion chamber 4-2 is staggered, and described gaseous mixture does the flowing of S shape successively by the first combustion chamber 4-1, the second combustion chamber 4-2 and the 3rd combustion chamber 4-3.Heat energy in combustion process like this is directly transformed into water channel capable of circulation, and heat is fully used.

As shown in Figure 3, preferably, described air-valve 10 adjusts air-valve automatically for gravity, it forms primarily of cover plate 10-1, described cover plate 10-1 top is articulated with oxygenation port 9 inside top, and the front face area of described cover plate 10-1 is greater than the area of oxygenation port 9, covers oxygenation port 9 by its deadweight.Be negative pressure (stove internal gas pressure is less than the outer air pressure of stove) state under normality in stove, when in stove, fire burning is more prosperous, negative pressure (draught head) increases, cover plate 10-1 overcomes its deadweight under the influence of air pressure, rotate relative to oxygenation port 9, open oxygenation port 9, outside air enters mixing bunker 8, oxygen needed for burning is provided, this project organization is simple, and without the need to electric control gear system, cost is low, not fragile, and the size can opened with combustion case (size of negative pressure determines primarily of combustion case) automatic adjustment oxygenation port 9 under cover plate Gravitative Loads.

Preferably, the driven timing also comprised for dredging fire bars dredges fire bars device 6 surely frequently.
