Steam Traps Affect Boiler Plant Efficiency

A steam trap is an automatic valve that holds the steam at the load until it gives up its heat energy and condenses to water (condensate). After the steam condenses to water, the steam trap allows only the condensate to pass, thereby contributing to plant efficiency. Since steam naturally releases heat, which causes condensation, another use

Is steam power in your future? - Backwoods Home Magazine

Round up to 4600. Our horsepower requirement then is 4600 watt/hours divided by 750, which is 6.1 horsepower (4600 / 750 = 6.1). Using 47 lbs of steam per horsepower hour to be consumed by our engine, we take the 6.1 and multiply it by 47 and we get 286.7 or basically 287 pounds of steam/water is required.

Increase Efficiency of Steam Power Plants - Industry Today

3.2.6 Thermal efficiency of conventional power plants. 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.
