  • Ratio Control and Metered-Air Combustion Processes

    By Allen Houtz 1 and Doug Cooper. A ratio control strategy can play a fundamental role in the safe and profitable operation of fired heaters, boilers, furnaces and similar fuel burning processes. This is because the air-to-fuel ratio in the combustion zone of these processes directly impacts fuel combustion efficiency and environmental emissions.Get Price

  • Control Engineering | How do burner combustion control

    Jan 13, 2015 · Each boiler has a boiler master, which is an A/M/bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that percentage to the fuel and airflow controllers. In MANUAL, the boiler master output is adjusted by the operator.Get Price
