3 Auxiliaries allow more heat to be produced. Section 2.4– Boiler AuxiliariesIntroductionAuxiliaries allow more heat to be produced.Minimizing heat loss is key to maximizing output.Efficiency is the key to generation.Combustion needs oxygen so airflow is key to heat production.Fuel type and size is key to combustion rate.Sizing of Auxiliaries is critical.
