Abstract:

This paper introduced the steam extraction transformation scheme of reheat steam and main steam lines for a homemade 300MW condensing power unit, and through theoretical calculation and experiment, it acquired the extraction flows at low and high temperature parts of reheating pipe under different load conditions for every unit. The study showed that through multisource industrial steam supply transformation of 300MW condensing power unit, it realized the maximum heat supply of 1.5MPa industrial steam per unit up to 170t/h, which provided a reference for the heating transformations of other 300MW condensing power units, such as Alstom and Dongfang.
