System Outline and Operational Status of Karita Power Station New Unit 1 (PFBC)

Abstract

Karita Power Station New Unit 1, which started commercial operation on July 3, 2001, has adopted the new power generation system PFBC, Pressurized Fluidized Bed Combustion, a combined cycle generation system. The system boasts high thermal efficiency, excellent environmental characteristics and compact size. Output from the steam turbine generator and gas turbine generator is 290MW and 75MW, respectively, with total output adjusted to 360MW, making the unit the largest PFBC plant in the world. In October 2002, combustion tests were conducted using an anthracite coal from Yangquan; and in April 2003, a world record was achieved for continuous operation hours of a PFBC plant. This paper focuses on the outline and operation status of Karita New Unit 1.
