The technical problems to be solved in the utility model provides a kind of waste heat that makes full use of in the exhaust duct cold water is carried out preheating, with fuel-saving energy-conserving and environment-protective steam oven.
For solving the problems of the technologies described above, a kind of energy-conserving and environment-protective steam oven of the utility model, comprise cooking stove and the steam raising plant that is installed on the cooking stove, steam raising plant comprise one have only the below for uncovered shell and with this shell coaxial, have only the below to be uncovered inner cover, inner cover is concordant with the bottom of shell and be tightly connected; The exhaust duct that the steam raising plant top is provided with steam output pipe and an end communicates with atmosphere, the other end communicates with the inner cover top, the place is provided with discharge outlet near the bottom, be provided with one deck heating tube at least in the described inner cover, the interlayer that internal layer is communicated with inner cover and shell formation is passed at the two ends of each heating tube respectively; Unlike the prior art be: steam raising plant top is provided with extra feed tank, has filler, exhaust duct to stretch out outside this extra feed tank on it; Be positioned on the exhaust duct of extra feed tank and be respectively equipped with the preheating water entrance and exit, be communicated with by the preheating pipe in the exhaust duct between this preheating water entrance and exit; In steam raising plant, be provided with the make-up water flow in pipes, be communicated with by the make-up water input channel between this pipeline and the outlet of described preheating water, and the water after the preheating is sent the return pipe of extra feed tank back in being provided with pipeline on this pipeline path.
The shell of described steam raising plant, inner cover and heating tube are preferably aluminum alloy materials and make.When said structure adopted aluminum alloy materials to make, described cooking stove can only use the liquid alcohol-group fuel.
The number of plies of described heating tube is five layers, is obstructed for the heating tube heat absorption that prevents each layer, and preferably the heating tube with adjacent two layers is crisscross arranged.The axis angle of preferred adjacent two layers pipeline is 70～75 °, is preferably 72 °.
For making this novel safer at work, also can safety anti-explosive pipe and the pressure-relief valve that communicate with atmosphere be set on described steam raising plant, to prevent the hypertonia in the steam raising plant.
Certainly, also some necessary instrument can be set on steam raising plant as required, as Pressure gauge, vapor (steam) temperature table, liquid level gauge etc.
Compared with prior art, advantage of the present utility model is:
1, one section preheating pipe is set in the exhaust duct, cold water in the supply pond is flowed through earlier in the interlayer of the inner cover that enters steam raising plant behind this preheating pipe again and shell, effectively utilizing the needs that reduced in the waste heat in the exhaust duct fuel, improving the thermal efficiency and also saved the energy;
2, the heating tube with adjacent two layers is crisscross arranged, and has prevented that effectively the heating tube heat absorption of each layer is obstructed, and has improved the thermal efficiency of this novel steam oven from another point of view;
3, shell, inner cover and the heating tube when steam raising plant adopts aluminum alloy materials to make, and when using the liquid alcohol-group fuel to carry out work in the cooking stove, because the heat conduction efficiency of aluminum alloy materials is higher, the combination of ferrous materials structure and diesel oil or gasoline relatively, can realize with relatively low external heat temperature, under the double condition of efficient heat conduction and recycling tail gas heat quantity, exhaust temperature is reduced to 110～120 degrees centigrade, improved the utilization rate of heat that fuel produces, can reach 85%, reduce the discharging of heat simultaneously; In addition, owing to adopt the liquid alcohol-group fuel, combustion product has only the waste gas such as carbon dioxide of small part based on water vapour, has reduced exhaust gas discharging.
