  • Why no 90+% efficiency steam boilers??? — Heating Help

    Mar 15, 2004 · It clearly shows where condensing boilers with low return-water and flue temperatures improve efficiency. The attached table shows conventional boiler efficiency at several flue temperatures and levels of excess air. With a steam boiler you are locked into the higher flue temperatures, but you can make sure you have the right amount of excess air.

  • Boiler Efficiency - an overview | ScienceDirect Topics

    The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

  • Economizer - Wikipedia

    Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design.In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers.. Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant.

    Overall Efficiency <p>Efficiency within a model group will tend to vary by the size (capacity) of the unit. Some products, like furnaces, may also be affected by installation orientation (horizontal, upflow, or downflow) or even by the nozzle used in installation, as is the case with boilers and oil furnaces.
