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
