<P>PROBLEM TO BE SOLVED: To provide a high temperature stream turbine power generation plant having a main steam temperature of 675°C or higher and an output of 100 MW or higher and constructed with a vertical type boiler having improved combustion efficiency while compatibly attaining high reliability and low cost. Ž<P>SOLUTION: The high temperature steam turbine power generation plant includes a boiler building including the vertical type boiler on the upper part of which a VHT turbine is installed, and a turbine building installed on a ground as a foundation. The VHT turbine has an inlet temperature of 675°C or higher, and an outlet temperature of 550-650°C. The VHT turbine is installed on the upper part of the vertical type boiler. A total Ni equivalent weight of the VHT turbine and a high pressure pipe between the boiler building and the turbine building is 4 tons or lighter. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
