Why the burner of gas hot water boiler can not ignite
Gas fired hot water boiler,as one kind of environmental protection industrial boiler,gets gradually the favor of market and people because of the more strict national environmental standards and its significant advantages.The burner is an important device mixing the air with fuel in a proper proportion to ensure the sufficient burning,the following conditions may cause that the burner of gas fired hot water boiler can't ignite:
The pressure of oil pump is low
After a long run,the highest pressure of oil pump will gradually drop,which causes the bad fuel automization,which will lead to the difficulty to ignite,and a lot dense smoke and the flame instability after ignition.The bad atomization caused by nozzle aging is similar to this.
The nozzle of burner has no fuel injection
The possible reason of that are the pump does not pump oil,oil pipeline leakage,oil pipeline blockage,etc.That the oil cut-off solenoid valve has no electricity also may cause that.
No high pressure for ignition
One reason of that is that the ignition transformer has no electricity(it may be caused by the undesirable contact of relay in the controller or power lines),the other reason is that no spark discharge produces,for the high pressure leaks.
