  • Working Principle | Boilers Guide

    Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.Get Price

  • Steam boiler pressure control – PID-tuner.com

    The steam that passes through the dryer, is produced from two heat sources: gas from an electricity generating turbine, and, if those gasses are insufficient, 2 gas fired burners. These heat sources are controlled by valves, further referred to as MV1 and MV2, respectively. These valves need to maintain the boiler pressure at setpoint.Get Price
