    Technical advice on boiler combustion control

    The boiler steam-production controller will measure this decrease in pressure and will increase fuel flow to the boiler. In the case of a natural-gas-fired boiler, the controller will proportionally open the fuel control valve. As the fuel flow is increased, the combustion air flow must also increase in order to maintain safe and efficient

    Safety controls for any fuel gas fired boiler

    If natural gas and air are inside the boiler when the burner is lit, the boiler can explode. High Natural Gas Pressure: A pressure switch in the natural gas line stops the burner if the gas pressure gets too high. If the natural gas pressure control valve fails, excessive gas can flow to the burner.
