The other boiler system is the fuel air-flow gas system, also referred to as the fireside of the boiler. This system provides the heat that is transferred to the water. The inputs to the system are the fuel and air required to burn the fuel [1]. The fuel and air chamber is also referred to as the wind-box. The outputs are the flow gas and ash [2].
