Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.

Reheat Cycle - an overview | ScienceDirect Topics

Generally, the efficiency of a Rankine cycle can be improved by increasing the pressure in the boiler. To avoid the increase of moisture in the steam coming out from the turbine, steam is expanded to an intermediate pressure and reheated in the boiler. In a reheat cycle, the expansion takes place in two turbines.The steam expands in the high-pressure turbine to some intermediate pressure, then

Modern Hydronic Designs, Controls, and Condensing Boilers

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.
