  • 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 …Learn More

  • 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.Learn More

  • Upgrade Boilers with Energy-Efficient Burners

    An efficient natural gas burner requires only 2% to 3% excess oxygen, or 10% to 15% excess air in the flue gas, to burn fuel without forming excessive carbon monoxide. Most gas burners exhibit turndown ratios of 10:1 or 12:1 with little or no loss in combustion efficiency. Some burners offer turndowns of 20:1 on oil and up to 35:1 on gas. A higherLearn More

  • Gas-Fired Boilers - Code Compliance Brief | Building

    Boilers are typically between 75% and 96% efficient in the primary process of heating the water, but any un-insulated heating water piping will lower the overall efficiency of space heating. In addition to the boiler unit, a gas-fired boiler requires a feed water supply, a boiler loop/heat delivery system (e.g., hydronic radiators or fan coil units), fuel supply piping and equipment, and a temperature control system.Learn More

  • Control Engineering | How do burner combustion control

    Jan 13, 2015 · The idea is this: The system needs to control fuel and air as "the amount of fuel and air needed for this percentage load." So we convert fuel flow to percent by multiplying it by a constant. We convert the airflow to percent by running mass flow through a PWC to get raw percentage, then trimming that percentage from the output of the O 2 trim loop. The resulting percent fuel and airflows will be controlled to match the boiler …Learn More
