Working principle of the present invention is as follows:
Normal ignition and combustion state: (1) it igniter fire: equipped with low-voltage capacitor discharge device inside igniter, separately speeds
It deflates and two gas inlet pipelines of compressed air, makes to burn in air by the capacitor electric discharge periodic off-gases that ignite.Level-one is quick
Switch valve 1, igniter acceleration switching valve 5 and corresponding first compressed air valve 8 are in the open state, remaining valve, which is in, closes
State.Burner combustion: the probe of flame detector 15 will have fiery signal through handling after detecting igniting pipette tips periodic off-gases burning
Device is fed back to control system, makes the periodic off-gases and compressed air hose road respective valves (second level high-speed switch of 10 import of burner
Valve 3, three-level acceleration switching valve 6, pressure-regulating valve 7) open so that periodic off-gases is burnt in boiler, the tune of load needed for ignition of the boiler
It is whole to be realized by the air conditioning baffle of pressure-regulating valve 7 and air register air inlet.
Blowing pipeline and displacement state: igniter needs that periodic off-gases respective line is purged and replaced before operation,
It needs to close periodic off-gases level-one acceleration switching valve 1, the first compressed air valve 8 and the first compressed air valve 9 at this time, it is fast to open nitrogen

Blowdown piping is passed through nitrogen, until nitrogen acceleration switching valve 2 is closed after combustible gas constituent analysis is qualified, it can be logical to ignition system
Enter periodic off-gases.
Safety interlocking state: safety interlocking state occurs in ignition system, and there are two types of situations, first is that flame detector 15 detects
To burning accident extinguishing, second is that pressure transmitter detects the lower limit value for periodic off-gases pipe atmospheric pressure lower than setting.When above two
In kind situation when any one generation, master controller 14 passes through control second level acceleration switching valve 3, three-level acceleration switching valve 6, pressure
Controller 13, flame detector 15, igniter acceleration switching valve 5, are gathered in avoid a large amount of combustible gases and are possible to send out in boiler
Raw detonation.
Pipeline pressure release state: after safety interlocking occurs for device or pipeline needs to overhaul, and requires to speed in pipeline
Deflation pressure release emptying, is mainly realized by opening quick release valve 4.
