The reasons why gas & oil fired boiler flameout

Unlike coal-fired boiler, gas fired boiler requires the use of burner to inject fuel into the boiler furnace, using the combustion chamber without fire grate facilities. Because no fuel ash produced after burning, there is no need of slagging facilities gas & oil fired boiler.
The oil or gas is injected into the furnace, and if the oil or gas-air mixing within a certain range, or turned off, it is easy to explode in boiler furnace. Therefore, automation combustion and control system are required.
While sometimes the gas & oil fired boiler will be flameout, the following summarizes the possible reasons:
(1) with excess water in oil;
(2) mechanical impurities or coking, causing nozzle clogging;
(3) oil pump failure caused a power outage or interruption to oil;
(4) vaporization of the oil pump to produce ultra-high population of oil, resulting interrupt fuel supply;
(5) filter or tubing plug, off valve spool plug the oil line, causing oil pressure drop.
These are summarized flameout reasons by professional oil & gas fired boiler manufacturer ZG. ZG gas & oil boiler furnace has an inspection hole for the use and maintenance. The roof has a blast doors; using automatic burners, water continuous electrically adjustable, high combustion efficiency. And multiple protection features, safe and reliable operation.
