Description
Technical field
Invention relates to gas furnace, a kind of Intelligent gas furnace being automatically adjusted air-fuel ratio.
Background technology
Existing gas furnace is that nature enters air, naturally mixes generation by the mistake tolerance of regulating gas with air and burns,
Air inlet at gas furnace is also provided with air door, and general air door is opened to maximum, do not made adjustments, in use, if
With bottled gas, when combustion gas reduces, air pressure reduces, and air is uneven to the mixing of combustion gas or ratio is not directly proportional, burning
Fire can turn yellow or combusting firepower is not enough, the effluent standard of the discharge gas serious non-compliance national requirements after burning, causes sky
Gas pollutes；If using gas pipeline gas, in peak period, air pressure is relatively low, and air is uneven with the mixing of combustion gas or compares
Example is not directly proportional, and burning fire can turn yellow or combusting firepower is not enough, the discharge gas serious non-compliance national requirements after burning
Effluent standard, cause air pollution；Gaseous species in China's burning has liquefied natural gas (LNG), natural gas (methane), liquid
Changing coal bed gas (HCL), the ratio best combustion value that different types of gas mixes with air is different, and present gas furnace is not
The gas of every kind can be realized best combustion.
Summary of the invention
In order to solve above-mentioned technical problem, invention provides one to burn fully, combustion gas after stain gas meets discharge standard,
It is suitable for liquefied natural gas (LNG), natural gas (methane), the intelligence being automatically adjusted air-fuel ratio of liquefaction coalbed (HCL) fuel gas buring
Can gas furnace.
The scheme realizing above-mentioned technical problem is:
A kind of Intelligent gas furnace being automatically adjusted air-fuel ratio, Intelligent gas furnace includes that body of heater (1), body of heater are fixed with on (1)
Burning jamb (11)；Controller (12) and combustion gas control handle switch (13) it is fixed with on described body of heater (1)；Described burning jamb
(11) being fixed with ignition electrode (14) on, ignition electrode (14) is connected with controller (12), and the air inlet of described burning jamb (11) is even
It is connected to air exhauster (110)；Described air exhauster (110) or burning jamb (11) or air exhauster (110) and burning jamb
(11) connecting between and have gas inlet pipe (111), gas inlet pipe (111) is connected with combustion gas control handle switch (13)；Described
Burning jamb (11) be provided with oxygen sensor (15)；Described air exhauster (110), oxygen sensor (15) and controller (12)
Connect.
Further: described air exhauster (110) connects electric air regulation valve (112).
Further: described air exhauster (111) is frequency conversion air exhauster.
A kind of Intelligent gas furnace being automatically adjusted air-fuel ratio of invention has the beneficial effect that after setting burning on the controller
Dusty gas discharge is less than national standard containing oxygen value, and gas furnace, when burning, is contained by the oxygen after oxygen sensor detection burning
Value also feeds back to controller, if too high oxygen level or too low, is controlled air exhauster by controller and carries out power adjustments, pass through merit
Rate regulation realizes rotational speed regulation, controls into air capacity by rotating speed, makes combustion gas mix fully burning with air；Air exhauster is with electronic
Air control valve coordinates the flow velocity of control wind to regulate control firepower size.
