Abstract
This paper introduces the technology and content of the first subcritical 300MW steam turbine transforma-tion using high-temperature circulating water for direct heating, and illustrates the similarities and differences with the 135MW stage units. On the basis of transformation technology of double back-pressure and dual rotor switch on 135MW stage units, Technical problems that commonality transformation of dual low-pressure cylinder, feeding water pump turbine transformation, and condensate polishing treatment system transformation have been solved on 300MW turbine unit to achieve direct heating using high-temperature circulating water. After transformation, the performance test results show that economic indicators of the unit have reached design values. Its energy-saving effect is remarkable.关键词
