  • Technical advice on boiler combustion control

    A low water cutoff turns off the burner or shuts off fuel to a steam boiler when the water level drops below a set point. A dry fired boiler can rupture or suffer significant failure. Low water cutoffs are another safety feature built into a steam boiler to help avoid damage and harm to the boiler.Learn More

  • Gas-Fired Boilers | Building America Solution Center

    The lowest efficiency boilers are atmospherically vented, Category I boilers. A Category I boiler operates with the flue at negative pressure with respect to the combustion appliance zone (CAZ), i.e., the room in which the boiler is located, and the stack temperature is above 140°F, which is hot enough to avoid condensation in the vent. The burner draws its combustion air from the CAZ.Learn More

  • gas fired steam boiler — Heating Help: The Wall

    I recently had a new boiler installed. It replaced a 140,000 btu unit. the new unit is 87,000btu. I was told by 3 contractors of Burnham that the old unit was to big for the house. My house is about 1100 sq ft. The new unit works fine but some of my radiators are not getting hot. The thermostat is set at 72 deg. plenty warm enough to heat the Learn More

    Increase the "burner stop" set point as much as possible in relation to other switchpoints or setpoints in the controls ; Raise the "burner start" set point abt. 0.2-0.3 bar above(!) the control set point. The effect will be that the burner stops all the time only in minimum load (load is reduced when it comes above the control set point).Learn More

  • Efficiency factors in natural gas fired steam boilers

    The main parameters that affect a steam boiler's efficiency are boiler load, combustion air, stack gas temperature, radiant heat loss, and acid dew point.

  • Boiler Efficiency - an overview | ScienceDirect Topics

    The most common test used for boilers is the flue gas analysis using an Orsat apparatus to determine the percentage by volume the amount of CO 2, CO, O 2, and N 2 in the combustion gas leaving the stack. Based on the flue gas composition and temperature, some adjustments can be made to tune-up the boiler and to determine the best air-to-fuel Learn More
