Abstract

Abstract:

Due to the increasing demand of regional heat supply, supercritical technology has been gradually applied and promoted in 300 MW cogeneration units. Technology optimizations have been carried out on the aspect of energy saving, while challenges have also been presented to unit operation and commissioning. In a 2×350 MW power plant, the features of 350 MW supercritical cogeneration unit are introduced, and the key technology of its commissioning is analyzed to suggest a solution for the problems in commissioning. The proposed commissioning technologies could be references for similar units commissioning.

Key words: supercritical cogenration unit, commissioning, boiler, turbine
