Steam turbines produce electricity using a combustible fuel and generator. In addition to producing electricity, useful heat can be recovered from the extraction port and back pressure port, and this recovered "waste" heat can be provided to a heating load. In this case, the steam turbine power plant would be operating in a Combined Heat & Power (CHP) or cogeneration mode. The energy performance of a steam turbine is influenced by a number of factors such as the type of fuel, the steam flow, the steam turbine operating pressure, superheated temperature, back pressure and availability. Other factors include the presence of an extraction port, the steam turbine efficiency and minimum capacity, the steam boiler seasonal efficiency and the return temperature. Refer to the Steam Turbine Schematic for more information.

Software & Data
The RETScreen Software Steam Turbine Model can be used worldwide to evaluate the energy production and savings, costs, emission reductions, financial viability and risk for central-grid, isolated-grid and off-grid steam turbine power projects, ranging in size from large scale coal-fired multi-turbine central power plants, to biomass-fired distributed power systems located at industrial facilities. In addition, landfill gas production can be estimated using an advanced landfill gas tool, and a biogas tool is provided to calculate the amount of biogas produced by the biological decomposition of various wastes. The software (available in multiple languages) also includes product, project and climate databases, and a detailed user manual.
