Description
Technical field
The invention belongs to heating furnace field, be specifically related to a kind of gas-fired heater.
Background technology
Gas-fired heater common at present, general heating furnace is all directly be discharged in air by the flue gas of burning, not only contaminated environment, and because insufficient and flue gas punching of burning is containing a large amount of heat energy, make to waste a large amount of heat energy, this and domestic advocate low-carbon (LC) society, energy-saving and emission-reduction are not inconsistent.Although some heating furnace is equipped with waste heat recovery apparatus in addition, there is equipment loaded down with trivial details, invest large problem.
Summary of the invention
For foregoing, the invention provides a kind of not clean-burning gas-fired heater rekindling utilization containing a large amount of heat energy flue gas.
For achieving the above object, the technical solution used in the present invention is:
A kind of gas-fired heater, comprise body of heater, blower fan is installed in described body of heater side, opposite side installs the decompression cabinet controlling gas pressure, the air heat exchanger that described blower and pipeline recycles with fume afterheat is connected, described decompression cabinet is connected with flame burner nozzle by pipeline, be connected by pipeline between described air heat exchanger with described flame burner nozzle, described air heat exchanger top connects smoke discharging pipe, bottom connects body of heater exhanst gas outlet, installs and control smoke discharging pipe unlatching and closed smoke evacuation butterfly valve bottom described smoke discharging pipe.
Pipeline between described blower fan and described air heat exchanger is installed the wind pressure measurement transmitter and wind speed hand-operated valve that can control separately air intake respectively; Pipeline between described decompression cabinet and described flame burner nozzle is installed the gas control valve controlling combustion gas input, valve and combustion gas hand-operated valve are cut in the combustion gas controlling gas pipeline closed soon.
Described upper of furnace body installs and measures the thermocouple of flame temperature.
Described air heat exchanger bottom sides connects the pipeline between described blower fan, and top-side connects the pipeline between described flame burner nozzle.
The beneficial effect that the present invention realizes is: by installing air heat exchanger at smoke outlet, with blower fan flue gas blown in flame burner nozzle by pipeline and rekindle, solve the problem of heat loss in the insufficient and flue gas of combustion of natural gas, natural gas is made to be able to thorough Thorough combustion, heat simultaneously in flue gas also reenters in body of heater, the controlled wind speed that intake stack and natural gas line are installed and the device of gas flow, achieve the Non-follow control of wind speed and flow and automatically control two kinds of control models, safer, reliably, cleverly air heat exchanger and smoke discharging pipe are connected together, namely achieve flue gas heat reclaim and burn again, reach again the object of simplifying waste-heat recovery device, reduce equipment investment.

Detailed description of the invention
As shown in Figure 1, a kind of gas-fired heater, comprise body of heater 1, blower fan 2 is installed in body of heater 1 side, opposite side installs the decompression cabinet 3 controlling gas pressure, the air heat exchanger 4 that blower fan 2 is recycled by pipeline and fume afterheat is connected, decompression cabinet 3 is connected with flame burner nozzle 5 by pipeline, be connected by pipeline between air heat exchanger 4 with flame burner nozzle 5, air heat exchanger 4 top connects smoke discharging pipe 6, bottom connects body of heater 1 exhanst gas outlet, installs and control smoke discharging pipe 6 unlatching and closed smoke evacuation butterfly valve 7 bottom smoke discharging pipe 6.Pipeline between blower fan 2 and air heat exchanger 4 is installed the wind pressure measurement transmitter 21 and wind speed hand-operated valve 22 that can control separately air intake respectively; Pipeline between decompression cabinet 3 and flame burner nozzle 5 is installed the gas control valve 31 controlling combustion gas input, valve 32 and combustion gas hand-operated valve 33 are cut in the combustion gas controlling gas pipeline closed soon.Body of heater 1 top installs and measures the thermocouple 8 of flame temperature.Air heat exchanger 4 bottom sides connects the pipeline between blower fan 2, and top-side connects the pipeline between flame burner nozzle 5.
By installing air heat exchanger at smoke outlet, with blower fan 2 flue gas got rid of in body of heater 1 blown in flame burner nozzle 5 by pipeline and rekindle, solve the problem of heat loss in the insufficient and flue gas of combustion of natural gas, natural gas is made to be able to thorough Thorough combustion, heat simultaneously in flue gas also reenters in body of heater 1, natural gas out after first through the pressure regulation of pressure reducer 3, make the pressure that combustion gas reaches suitable, then flame burner nozzle 5 is entered by pipeline, the wind pressure measurement transmitter 21 that intake stack and natural gas line are installed, wind speed hand-operated valve 22, gas control valve 31, valve 32 is cut in combustion gas soon, combustion gas hand-operated valve 33, carry out the flow of controlled wind speed and combustion gas, achieve the Non-follow control of wind speed and gas flow and automatically control two kinds of control models, safer, reliably, flue gas in body of heater 1 to enter in air heat exchanger 4, when smoke evacuation butterfly valve 7 in the smoke discharging pipe 6 of air heat exchanger 4 upper end closes, flue gas enters flame burner nozzle 5 place by pipeline along with the wind in blower fan 2, rekindle, simultaneously blower fan provides oxygen needed for burning for body of heater, after burning terminates, smoke evacuation butterfly valve 7 is opened, after Thorough combustion, remaining a small amount of gas is discharged to the external world, to greatest extent while thin device, reach combustion gas Thorough combustion, heat recovery and utilization, free of contamination object, reduce the investment of equipment.
