Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Figure 1-4, the present invention includes body of heater 1, described body of heater 1 top is provided with the air-supply passage 3 of air inlet, some fresh air inlets 9 are offered bottom air-supply passage 3, air-supply passage 3 inwall offers some secondary intake openings 8, one time fresh air inlet 9 is connected with bottom burner hearth 2 with an air intake passage 10 between body of heater 1 by burner hearth 2 outer wall, air-supply passage 3 top is provided with the flue 6 of the annular be connected with burner hearth 2, flue 6 passes through to be connected into mouth with burner hearth 2, secondary intake opening 8 is directly connected with burner hearth 2 top, some electrothermal modules 4 utilizing thermo-electric generation are set between flue 6 and air-supply passage 3.See Fig. 5, there is space, fill heat insulation layer 5 in space between some electrothermal modules 4, wherein, heat insulation layer 5 is the flexible material of thermal conductivity factor 0.01 ~ 0.2W/ (mK).Air inlet 13 is opened on air-supply passage 3 sidewall, and air-supply passage 3 sidewall is also provided with the gas outlet be connected with air-supply passage 3, gas outlet is disposed adjacent with air inlet; Air inlet and enter mouth and be arranged at the same side, and air inlet 13 is arranged on immediately below mouth, be beneficial to and fully carry out heat exchange, air inlet place arranges and is powered and the air blast driven by electrothermal module 4, and the air that gas outlet is discharged directly sends into indoor (or in tent).High-temperature plastic is adopted to bond (high-temperature plastic is the temperature of at least resistance to 400 DEG C) between flue 6, electrothermal module 4, air-supply passage 3.
A described fresh air inlet 9, the aperture of secondary intake opening 8 increase gradually from air inlet to gas outlet (aperture of fresh air inlet 9, secondary intake opening 8 increases gradually from the circumferencial direction aperture of air inlet to gas outlet along air-supply passage), a fresh air inlet and secondary intake opening gross area ratio are 8.0 ~ 10.0, can increase an intake like this.Air in air-supply passage of the present invention enters an air intake passage 10 by a fresh air inlet, passes through the further heat exchange with hearth outer wall from top to bottom, and temperature raises, and in burner hearth combustion fully and more stable, heat release rate is fast, and time reinforced, fire box temperature fluctuation is little; In burner hearth, flue gas burns again through the unburned flue gas of secondary intake opening, and burner hearth and flue-gas temperature raise.
Fire door 7 is offered in body of heater 1 upper end of the present invention, is provided with fire grate in the burner hearth of body of heater 1, and the below of burner hearth arranges ash bucket 11, and the lower end of body of heater 1 arranges the supporting leg 12 for supporting body of heater; In the present invention, burner hearth 2 is cylindrical, and being provided with in burner hearth 2 can the combustion chamber assembly of movement.
In the present invention, between flue 6 and air-supply passage 3, electrothermal module 4 is set, flue 6 enter mouth and exhaust opening is disposed adjacent on flue 6 sidewall, from entering flue gas that mouth enters flue 6 around burner hearth after 2 one weeks, discharge from exhaust opening, the exhaust opening place of flue 6 arranges chimney seat.In the present invention, flue was around burner hearth 2 one weeks, and flue gas is discharged around burner hearth in flue for 2 one weeks, extends flue gas flow; The air inlet 13 of air-supply passage 3 and flue 6 enter immediately below mouth, between air-supply passage 3 and flue 6, heating surface area is large, makes full use of the heat of flue gas, and the air heats in air-supply passage 3 is fast, and air-supply heating speed is fast, and heat utilization efficiency is high.During use, because the flare of burner hearth 2 heats flue 6, the wind of air blast blowout enters the air-supply passage 3 of flue 6 bottom, through with the heat exchange of flue after become hot blast and to send into through gas outlet indoor (in tent), make heating space rapid temperature increases, air blast is powered by the electrothermal module 4 between flue 6 and air-supply passage 3, improves heat utilization efficiency.Radiation and heat convection are carried out in air-supply passage 3 and indoor, and the wind pushing temperature of gas outlet decreases, and be conducive to the cooling of temperature-difference power generation module cold junction, enhance heat exchange simultaneously, utilization efficiency of heat energy significantly improves, and heating effect is better.
Operation principle of the present invention is: be provided with electrothermal module between flue and air-supply passage, the flue gas that hearth combustion produces passes through electrothermal module and the air-supply passage heat exchange of annular flue and downside, electrothermal module utilizes the temperature difference between flue and air-supply passage to produce the air-supply of driven by power air blast, air blast blasts the air of air-supply passage and the cold junction heat exchange of electrothermal module, burner hearth is sent into for burning through feeding fresh air inlet, secondary intake opening by the air heated, fuel is added by charge door, ensures the continuity of burning.
