How to Destroy a Boiler -- Part 1

A gas/oil boiler has no inventory or bed of fuel. When you trip the burner for all practical purposes the heat input immediately stops. With solid fuel units however a fairly large mass of bark coal etc. is still on the grate and even though starved of air by the loss of the forced draft fan these units have more "thermal inertia" and ...

Technical advice on boiler combustion control

The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra reached this temperature by receiving fuel energy in other words fuel was purchased to heat the extra .
