ABSTRACT:
A boiler having a combustor for combusting an air/gas fuel mixture, the combustor including a heat exchanger which conducts coolant therethrough surrounding the combustion chamber and a fan coupled to an air line provides a flow rate of air in the air line. A gas line is coupled at one end to a source of gas and at another end to the air line so as to produce a mixture of gas and air. Means for measuring a property of the air/gas fuel mixture characteristic of its combustibility are utilized. A valve coupled to said gas line is operative to control a flow rate of gas in response to a control signal from the means for measuring. A temperature sensor takes a temperature measurement of the coolant after passing through the heat exchanger and transmits the temperature measurement to the speed control unit. The speed control unit slows down the speed of the fan when the coolant temperature approaches a preset limit.
