Highly Efficient Biomass Plants Thanks to Reheat Solutions (Room Garuda 7A, 1st Floor)

With the rising prices of biomass used as fuel, the demands placed on the efficiency of a power plant are also increasing. High efficiencies allow for economical operation of the power plant and competitive power generation compared to electricity production from conventional energy sources. Industrial steam turbines with a power output of up to 250 MW and live steam parameters of up to 565 ° C / 165 bar achieve maximum efficiency with a double casing reheat solution. Employing this configuration, Siemens installs a high-speed steam turbine, which is coupled to the generator by a gearbox. A second steam turbine directly drives the generator. In comparison with a conventional single-case solution this setup can achieve up to two percent higher efficiency. The paper describes the configuration and its benefits for customers interested in a highly efficient biomass plant operation.
