    Tips for combustion analysis of commercial boilers | 2016

    Most boilers are designed to supply between 12 and 15 parts of air for each part of gas. Some industrial facilities can reduce the air-to-fuel ratio even lower than 20% by using an oxygen or O2 trim system. This system uses a sensor in the flue to monitor oxygen content while the burner is running and constantly adjusts the air-to-fuel ratio.

    A common cause of explosion is the runaway firing condition that takes place when the boiler’s burner does not shut off. In this case, when the hot-water heater is connected to the city water supply on one side and the building hot-water service on the other, the check valve will shut off and no back pressure will go into the city side.
