Analysis and Discussion on Warm-up Mode of Large-scale Steam Turbine

Warm up is a core problem of steam turbine in start-up processing. A reasonable way to warm up is important for the life and safety of the turbines. Based on the design technology, industrial test and operational experience, each turbine overseas manufacturer determines different warm-up schemes, which is used as technical specifications for domestic turbine manufactures. The paper introduces typical warm-up mode of the turbine and several important issues of in start-up processing, and analyzes the function ＆characteristics of each warm-up process as well as the design idea ＆ advantages of the warm up schemes proposed by the overseas turbine manufacturers.
