      Specific Steam Consumption | Advanced Steam Traction

      Specific Steam Consumption is defined as the steam consumed by a locomotive’s cylinders per unit output of power. It is typically measured in kg/kWh or kg/KJ. A locomotive’s Specific Steam Consumption carries important implications as may be deduced from one of Porta’s favourite equations: Thus for any given boiler output, a locomotive’s power can be increased by reducing its specific steam …

      The ratio of the fuel mass flow of an aircraft engine to its output power, in specified units. Specific fuel consumption (abbreviated sfc or SFC) is a widely used measure of atmospheric engine performance. For reciprocating engines it is usually given in U.S. Customary units of pound-mass per hour per horsepower [ (lbm/h)/hp or lbm/ (hp·h)], and International System (SI) units of kilograms per hour per …

      How much steam is required to generate 1MW of electricity

      This is called Specific Steam Consumption (SSC). Efficient machines are having Low Specific steam consumption i.e, to generate 1 MWhr they consume less steam, which is always preferable. Mostly with the size of the turbine it is reduce. Our 156 MW Steam turbine use to have SSC of around 0.37 mw/tn. Near about 2.7 Tons per MW generation.
