Assessment of turbine generator technology for district heating applications

Technical Report ·
OSTI ID:6495954
Steam turbines for cogeneration plants may carry a combination of industrial, space heating, cooling and domestic hot water loads. These loads are hourly, weekly, and seasonally irregular and require turbines of special design to meet the load duration curve, while generating electric power. Design features and performance characteristics of large cogeneration turbine units for combined electric generation and district heat supply are presented. Different modes of operation of the cogeneration turbine under variable load conditions are discussed in conjunction with a heat load duration curve for urban heat supply. The performance of the 250 MW district heating turbine as applied to meet the heat load duration curve for Minneapolis--St. Paul area is analyzed, and associated fuel savings are estimated.
