Abstract： In order to meet the demand of improving the technical and economic efficiency of waste incineration power generation， a 25 MW medium-temperature sub-high pressure reheat steam turbine is designed. This unit is the first domestic waste power generation reheat unit， which adopts the combination design of header single-cylinder reheat， high speed， and impulse and reverse， and has the characteristics of compact structure， flexible operation， and high economic efficiency. The successful operation of this unit has a high guiding significance for the small reheat steam turbine technology and waste power generation industry.

Keywords： garbage power generation; medium temperature and sub-high pressure; main pipe reheat; single cylinder; reverse combination; high speed
