Description

Far infrared catalytic energy saving gas furnace

The utility model is the daily necessities in the family kitchen field, is to improve the culinary cuisine condition, improves energy-conservation timeliness, thereby realizes the economy that it is considerable.

As everyone knows, be the stove and accessory of fuels sources with coal gas, liquefied gas, natural gas, on current market, have general single general character, as: traditional cast iron wind tunnel type burning or the burning of sintered ceramic plate formula, the most general with the wind tunnel type burning.The application technology state is simpler, needs the auxiliary air amount combustion-supporting, primary air amount insufficient and combustion gas and last completing combustion, and energy-saving effect is not significantly or equal zero.Especially to the source of the gas deficiency, the combustion gas that makings is lower brings extremely inconvenience to use, shows low with regard to its economy side.

The purpose of this utility model is to develop new material, and new technical field solves the deficiency of present stove and accessory.Use not sooting stove and accessory and pollution living environment for a long time, have fabulous wind resistant character, the fire combustion is difficult for putting out, basic generation and the discharging of eliminating carbon monoxide and nitrogen oxide, realize energy-efficient, thereby improve the economy of people's daily life, bring great convenience to family life.

The main points of technical solutions of the utility model are: use far infrared high radiation coefficient material, matrix surface at combustion head, the matrix surface of reflector, coating belongs in the 2nd, the 3rd cycle of the periodic table of elements more than at least a element, with metal oxide, carbide, nitride and the boride more than at least a element in the 4th, the 5th cycle mix quality coating.Because the radiant heat transfer energy is by the biquadratic decision of heater temperature, combustion head and combustion chamber are air-tight state, so response speed is exceedingly fast extreme temperatures.Because high burning velocity and temperature, the stove and accessory combustion chamber forms vacuum, once measures under the atmospheric outside effect of air thereupon, is sucked fully, and enters the combustion chamber with combustion gas mixing, makes it combustion gas and obtains catalysis and burn cmpletely.Reflector adopts the high radiation paint of vitreous enamel, and characteristics such as difficult drop-off and good vibration strength, the clean property of water not only make radiativity intensity even, and make radiation intensity not remarkable with the decay of square distance.The reflector outward flange is hemisphere face or parabola, utilizes airborne N ₂, O ₂, H ₂Deng diatomic gas, to the non-absorbent characteristics of far-infrared radiation, to reduce scattering and disappearing of radiation.Because reflector and body of heater are gas gap, the conduction loss of decay thermal source.Because of being normally open with combustion head, air enters from the bottom again, and the convection current of increase and calandria improves heating quality.Nozzle adopts magnetic technique, 180 ° of quality that improve combustion gas with the refinement combustion gas of opposed pair of magnetic field upset phase difference.In a word, the utility model improves the energy-conservation tangible index of stove and accessory more than 30%, brings considerable economy for people's daily life.

Invention advantage of the present utility model is: compare with present stove and accessory, adopt the far infrared radiation heating material, heating furnace unlike equal-wattage has the generation more heat, energy-conservation key is to improve the utilization rate and the heating quality of heat energy, has realized the approximate corresponding of radiation and absorption spectrum.The speed that adds radiation propagation is fast, can not pass through any medium, has reduced the loss in the thermal energy transfer process widely.Because the general power of radiant heat transfer is by the biquadratic decision of heater temperature, with Wavelength-independent.So response speed is exceedingly fast, synchronous with burning, thus make heat temperature raising fast.Adopt reflector to make the decay of reflected intensity not remarkable, nozzle adopts two magnetic field techniques, and the refinement combustion gas improves the quality of source of the gas, and once to measure air fully and combustion gas catalysis is burnt cmpletely, improves energy-conservation quality factor.

The configurable electronic impulse sparking of the utility model.Piezoelectricity sparking or the like is beneficial to easy to use.Also configurable thermocouple assembly is closed after the control combustion gas is extinguished, automatically to strengthen the security of using.

Accompanying drawing: (1) is the section of structure of far infrared catalytic energy saving stove and accessory.

(2) be the two magnetic field structure enlarged drawings of nozzle.

(3) be ceramic matrix far infrared combustion head structure enlarged drawing.

(4) be far-infrared reflection cover structure profile.

Below in conjunction with description of drawings a kind of embodiment of the present utility model.

Accompanying drawing (1) is the section of structure of the utility model far infrared catalytic energy saving stove and accessory, and it is formed body of heater (1) by combustion chamber and outer wall and forms basic structure with injector (2), combustion head (3), parabolic reflector (5).Accompanying drawing (2) is the two magnetic field structure enlarged drawings of nozzle, and combustion gas by by the two magnets of I, II and overturn that 180 ° of magnetizing fields of forming of phase difference (8) are magnetized, refinement, changes the quality of combustion gas by nozzle (7), is mixed into the combustion chamber with sufficient once amount air.Accompanying drawing (3) is the structure enlarged drawing of ceramic honey comb matrix far infrared combustion head, mixed combustion gas is by the combustion head (3) of ceramic honey comb matrix, through far infrared high radiation coefficient dope layer (4) high-velocity combustion, temperature raises with biquadratic speed, makes combustion gas be able to catalysis and also burns cmpletely.Accompanying drawing (4) is a far-infrared reflection cover structure enlarged drawing.Intensity is not remarkable with square decay of distance when making radiation, adopts reflector (5) and vitreous enamel far infrared high radiation coefficient coating (6).Reflector (5) outward flange is with hemisphere face or parabolic minimizing scattering, because reflector (5) is normally open with ceramic honey comb matrix combustion head (3), air charges into from the bottom, forms convection current with calandria.Reflector (5) is the air gap state interval with body of heater (1), and the conduction loss of decay thermal source improves the thermal source quality, thereby energy-efficient, improves its economic benefit.

The high radiative material of the far infrared of this kind of embodiment, adopting weight ratio is zirconium dioxide (ZrO ₂) and chromium trioxide (Cr ₂O ₃) 3.5, and cobalt, manganese, aluminium, barium, zinc, potassium, admire, iron, the multiple compound of silicon forms, and is pulpous state or oily, coating obtains with the method for brushing, spraying, combustion knot.Extremely strong or the high-strength size decision of combustion head temperature with the combustion gas open amount.Facts have proved that also can obtain higher emittance with regard to little gas quantity combustion head, cooking speed is very considerable.The Energy distribution of the utility model combustion head is even, can use for a long time continuously.
