The gas heater of the present invention of semiconductor thermo-electric generation apparatus is housed, stops burning primarily of burner, heat exchanger, condenser, axial flow blower, electronic striking and gear regulating gas valve, the automatic regulating gas valve of water temperature, ion or pressure and protect gas valve to form.Burner is made up of burning zone, premixer, gas nozzle and electronic impulse ignition apparatus, during igniting, the automatic regulating gas valve of twisting water temperature, selects suitable set water temperature, depress the knob of electronic striking and gear regulating gas valve again, then twist the knob of electronic striking and gear regulating gas valve.Through ion or pressure stop burning the first via combustion gas of protection gas valve by the electronic striking of pressure and the lighting valve of gear regulating gas valve after, then to be sprayed from ignition burner by first gas pipeline, spray into above burning zone, lighted by electronic impulse ignition apparatus.Through ion or pressure stop burning the second tunnel combustion gas of protection gas valve by the gear valve of electronic striking and gear regulating gas valve after, then enter airduct by second gas pipeline and to spray from gear regulating gas nozzle and mix with air, then enter premixer.Through ion or pressure stop burning protection gas valve the 3rd tunnel combustion gas by lower water temperature gas valve after, then by the 3rd gas pipeline also enter airduct from lower water temperature gas nozzle ejection mix with air, then enter premixer.After two strands of gas-air bodies enter premixer, then through the flame ignition that burning zone is sprayed by ignition burner.Unclamp the knob of electronic striking and gear regulating gas valve, the lighting valve of electronic striking and gear regulating gas valve is closed.Rotate the knob of electronic striking and gear regulating gas valve, select suitable gear, namely regulate the combustion power of burner.Water temperature can turn down the gas quantity entering the 3rd gas pipeline and spray from lower water temperature gas nozzle automatically higher than the automatic regulating gas valve of water temperature during setting value, water temperature can increase the gas quantity entering the 3rd gas pipeline and spray from lower water temperature gas nozzle automatically lower than the automatic regulating gas valve of water temperature during setting value.Above burning zone, semiconductor thermo-electric generation apparatus is housed, semiconductor thermo-electric generation apparatus is that axial flow blower is powered.The blast pipe of axial flow blower is attached to the back side cooling semiconductor of semiconductor thermo-electric generation apparatus, and the Part I wind of axial flow blower blowout enters the premixer of burner.Running water is introduced into condenser, then enters heat exchanger.The burning zone of burner is double layer cell shape alloy catalytic net or foamed alloy plate, and upper strata honeycomb catalyst alloy network or foamed alloy plate are resistant to elevated temperatures honeycomb catalyst alloy network or foamed alloy plate.During igniting, the automatic regulating gas valve of twisting water temperature, selects suitable set water temperature, then depresses the knob of electronic striking and gear regulating gas valve, then twists the knob of electronic striking and gear regulating gas valve.Through ion or pressure stop burning protection gas valve first via combustion gas by pressure electronic striking and gear regulating gas valve lighting valve after; sprayed from ignition burner by first gas pipeline again; spray in the interlayer of double layer cell shape alloy catalytic net or foamed alloy plate, lighted by electronic impulse ignition apparatus.Through ion or pressure stop burning the second tunnel combustion gas of protection gas valve by the gear valve of electronic striking and gear regulating gas valve after, then enter airduct by second gas pipeline and to spray from gear regulating gas nozzle and mix with air, then enter premixer.Through ion or pressure stop burning protection gas valve the 3rd tunnel combustion gas by lower water temperature gas valve after, then by the 3rd gas pipeline also enter airduct from lower water temperature gas nozzle ejection mix with air, then enter premixer.After two strands of gas-air bodies enter premixer, then through the flame ignition that lower floor's honeycomb catalyst alloy network or foamed alloy plate are sprayed by ignition burner.The semiconductor thermo-electric generation apparatus be equipped with above upper strata honeycomb catalyst alloy network or foamed alloy plate, the blast pipe of axial flow blower is attached to the back side cooling semiconductor of semiconductor thermo-electric generation apparatus.Semiconductor thermo-electric generation apparatus is heated rear generation voltage driven axial flow blower and is rotated, axial flow blower blowout Part I wind enters the premixer of burner through airduct, the second part wind of axial flow blower blowout is blown into the space of the interlayer of double layer cell shape alloy catalytic net or foamed alloy plate from the edge of double layer cell shape alloy catalytic net or foamed alloy plate.Heat exchanger lower end and burner are tightly connected by pad, pad have polycrystalline glass window.
Eliminate the method that the gas heater noise of the present invention of semiconductor thermo-electric generation apparatus is housed: during igniting, the automatic regulating gas valve of twisting water temperature, select suitable set water temperature, depress the knob of electronic striking and gear regulating gas valve again, then twist the knob of electronic striking and gear regulating gas valve.Through ion or pressure stop burning protection gas valve first via combustion gas by pressure electronic striking and gear regulating gas valve lighting valve after; sprayed from ignition burner by first gas pipeline again; spray in the interlayer of double layer cell shape alloy catalytic net or foamed alloy plate, lighted by electronic impulse ignition apparatus.Through ion or pressure stop burning the second tunnel combustion gas of protection gas valve 7 by the gear valve of electronic striking and gear regulating gas valve after, then enter airduct by second gas pipeline and to spray from gear regulating gas nozzle and mix with air, then enter premixer.Through ion or pressure stop burning protection gas valve the 3rd tunnel combustion gas by lower water temperature gas valve after, then by the 3rd gas pipeline also enter airduct from lower water temperature gas nozzle ejection mix with air, then enter premixer.After two strands of gas-air bodies enter premixer, again through lower floor's honeycomb catalyst alloy network or foamed alloy plate, the flame ignition that these a small amount of gas-air bodies are sprayed by ignition burner, but detonation sound can not be produced, and the flame ignition that these a small amount of gas-air bodies are sprayed by ignition burner, be all carry out in the space closed, sound can not be passed to outside.Unclamp the knob of electronic striking and gear regulating gas valve 8, the lighting valve of electronic striking and gear regulating gas valve is closed.Rotate the knob of electronic striking and gear regulating gas valve 8, select suitable gear, namely regulate the combustion power of burner.Water temperature can turn down the gas quantity entering the 3rd gas pipeline and spray from lower water temperature gas nozzle automatically higher than the automatic regulating gas valve of water temperature during setting value, water temperature can increase the gas quantity entering the 3rd gas pipeline and spray from lower water temperature gas nozzle automatically lower than the automatic regulating gas valve of water temperature during setting value.Semiconductor thermo-electric generation apparatus is heated rear generation voltage driven axial flow blower and is rotated.Axial flow blower blowout Part I wind enters the premixer of burner through airduct, the Part II wind of axial flow blower blowout is blown into double layer cell shape alloy catalytic net or foamed alloy plate holder sheaf space from the edge of double layer cell shape alloy catalytic net or foamed alloy plate.Because the burning of mist on lower floor's honeycomb catalyst alloy network or foamed alloy plate of combustion gas and air is burn incompletely, do not need too many air support, thus the air sent into from burner airduct porch few, can not sound of the wind be produced.And the front end of axial flow blower is connected to blast pipe, the rear end of axial flow blower is connected to discharge pipe, and the sound that axial fan blade beating air passes to outside is very little.The burning of mist on lower floor's honeycomb catalyst alloy network or foamed alloy plate of combustion gas and air is the carbon monoxide that produces of burn incompletely and carbon particulate, a large amount of air enters interlayer from the interlayer edge of double layer cell shape alloy catalytic net or foamed alloy plate, after mixing with the air of these carbon monoxide and carbon particulate, Thorough combustion on upper strata honeycomb catalyst alloy network or foamed alloy plate.Carbon monoxide and the burning of carbon particulate on upper strata honeycomb catalyst alloy network or foamed alloy plate are the low flame combustions of sufficient infrared ray, can not produce the burning sound of roars of laughter roars of laughter.Because heat exchanger lower end and burner are tightly connected, the sound that the burning on upper strata honeycomb catalyst alloy network or foamed alloy plate of carbon monoxide and carbon particulate produces can not pass to outside.The combustion gas entering burner premixer is more, combustion gas is burnt on lower floor's honeycomb catalyst alloy network of burner or foamed alloy plate and upper strata honeycomb catalyst alloy network or foamed alloy plate, and the heat produced is more, and the temperature above the upper strata honeycomb catalyst alloy network of burner or foamed alloy plate is higher.Temperature above the upper strata honeycomb catalyst alloy network of burner or foamed alloy plate is higher, the voltage that semiconductor thermo-electric generation apparatus sends is higher, thus axial flow blower rotating speed wind supply quantity that is faster, axial flow blower is larger, combustion gas and more air pre-mixing are closed, and coordinate combustion gas to burn on lower floor's honeycomb catalyst alloy network or foamed alloy plate; Also having more wind enters between the interlayer of double layer cell shape alloy catalytic net or foamed alloy plate, supports that the mist of combustion gas and air burns on lower floor's honeycomb catalyst alloy network or foamed alloy plate; After more air mixes with carbon monoxide and carbon particulate, the low flame entered on upper strata honeycomb catalyst alloy network or foamed alloy plate burns fully, makes upper strata honeycomb catalyst alloy network or foamed alloy plate produce infrared ray.The combustion gas entering burner premixer reduces, the mist of combustion gas and the air heat produced that burns on burning on lower floor's honeycomb catalyst alloy network or foamed alloy plate of burner and on upper strata honeycomb catalyst alloy network or foamed alloy plate also reduces, and the temperature above the upper strata honeycomb catalyst alloy network of burner or foamed alloy plate will reduce; After temperature above the upper strata honeycomb catalyst alloy network of burner or foamed alloy plate reduces, the voltage that semiconductor thermo-electric generation apparatus sends also can reduce, axial flow blower rotating speed also will reduce, the wind supply quantity of axial flow blower also can reduce, and makes combustion gas and supports that the air capacity of fuel gas buring matches.Because the burner 1 burning zone area of gas heater is little, if adopt gravity-flow ventilation, combustion gas would not on the burning zone of burner Thorough combustion; Only have and force air feed with axial flow blower, just can make combustion gas Thorough combustion on the burning zone of burner.
The present invention of temperature sensor and flame detector is housed by conputer controlled instrument control system, it does not use semiconductor thermo-electric generation apparatus, but uses civil power.Conputer controlled instrument controls the rotating speed of axial flow blower according to the information of temperature sensor and flame detector.
