The utility model is further set to: the outer wall of described high temperature smoke-box is heat preservation sandwich layer, and heat preservation sandwich layer is communicated with combustion-supporting chamber, and described air intake house steward is connected with heat preservation sandwich layer.
The utility model is further set to: described high temperature smoke-box by flue with the concrete structure that combustion chamber and smoke evacuation chamber communicate is respectively: the outlet flue arranging on combustion chamber is provided with through the mouth that enters arranging on the smoke pipeline being communicated with high temperature smoke-box after steam generating chamber, smoke evacuation chamber and is provided with the smoke discharging pipe being communicated with high temperature smoke-box through after steam generating chamber.
The utility model is further set to: described outlet flue is arranged on the upside of combustion chamber, described in enter mouth be arranged on smoke evacuation chamber upside.
By adopting technique scheme, the technique effect that the utility model reaches is:
1, feed pipe is communicated with air intake house steward, by air intake house steward, for feed pipe, blowing to assist the fuel that enters feed pipe can be brought in burner hearth rapidly, there will not be the hidden danger that does not enter burner hearth and directly ignited, simultaneously, from feed pipe, enter into wind in the burner hearth flame can be by the fuel combustion time charging mouth of pipe that blows off, and then can not make fuel just depart from feed pipe with regard to burned flame ignition; Adopt in this way, effectively raise the utilization rate of energy, and the efficiency of generator is also further increased;
2, air intake house steward is communicated with combustion chamber, and effectively auxiliary combustion chamber is combustion chamber igniting when igniting, makes the igniting of burning more convenient;
3, by high temperature smoke-box is set, in the cigarette that makes after burning to produce with heat can be reused, effectively raise the utilization rate of energy, allow heat in cigarette in the process through high temperature smoke-box, the process that can lead to heat transfer transfers heat to steam generating chamber;
4, heat preservation sandwich layer is set, effectively guaranteed that high temperature smoke-box energy can not spill into the external world, the utilization rate of energy is further promoted, heat preservation sandwich layer communicates with air intake house steward, combustion-supporting chamber respectively, make the heat of heat preservation sandwich layer can be recycled recycling, the cold wind entering from air intake house steward becomes the hot blast with uniform temperature by heat preservation sandwich layer, and then enters into combustion-supporting chamber again, make combustion-supporting effect become more remarkable, also can guarantee that the temperature of heat preservation sandwich layer can be not too high simultaneously.
