S2. start supply air system 1, and purge air quantity is provided.Herein, preferably air damper controller 12 is opened to maximum shape
State, so that the ventilation quantity in ventilation shaft 2 reaches maximum.
S3. supply air system 1 is adjusted, igniting air quantity is provided, and controls pyrophoric body and igniter work, carries out pre- point
Fire.
S4. supply air system 1 is adjusted, burning air quantity is provided, and controls burning spray head 3 and the work of pressure maintaining valve 42, makes burner
Stablize flame and continues pre-determined stability burning time；
S5. supply air system 1 is adjusted, provides big aperture air quantity, and adjust pressure maintaining valve 42, fires the combustion gas sprayed in burner sufficiently
It burns.
Specific Booting sequence is as follows: when gas burner starts, after program controller 26 is powered, starting internal processes self-test, together
When, air damper controller 12, which controls the rotation of baffle 14, is in close state air door, after program self-test, it is in standby,
When the equal limit switches of gaseous-pressure switch 291 allow, program controller 26 starts to start, and control air damper controller 12 opens air door
To high fire aperture state, while blower motor 111 starts, and provides purge air quantity, is pre-purged with being blown into air, subsequently will
Air door is opened to igniting aperture state, provides igniting air quantity, prepares igniting.Entire prepurge stage, fan pressure-tapping device 29 are surveyed
Air pressure is measured, only air pressure is maintained in a sufficiently high level, and prepurge process could continue to carry out.Work as air door
After igniting aperture state, gas valve 45 is opened, and combustion gas is first passed through ignition tube 44, and then igniter 5 works, and exports high electricity
It presses to igniter head 51, to generate ignition spark, realizes prefiring.Then 26 power transmission of program controller is to pressure maintaining valve 42 and butterfly valve 43,
After pressure maintaining valve 42 and butterfly valve 43 are opened, combustion gas reaches burning spray head 3, and the air provided with supply air system 1 mixes, then started
Full burning.After the opening of gas valve 45 in 2 seconds, flame perceptron 27 should detect the presence of flame, only in this way, program controller 26
Just continue subsequent program, otherwise, program controller 26 locks and disconnect pressure maintaining valve 42 and butterfly valve 43 stops gas supply, same to alarm.?
Igniting is normally and after stable burning pre-determined stability burning time, the driving air door of air damper controller 12 to high fire aperture state, and root
Gaseous-pressure after adjusting pressure maintaining valve 42 according to the air pressure that fan pressure-tapping device 29 measures reaches steady with regulating gas amount
Fixed, efficient burning purpose, pre-determined stability burning time is preferably 3 seconds.Hereafter, gas burner is according to each limit switch
It is required that realizing large and small fire conversion automatically and shutting down.In addition, in entire combustion process, flame perceptron 27 and fan pressure-tapping device 29
Gas burner is carried out and is monitored.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
