GE To Supply Controls To Mississippi Power Plant

Posted on March 7, 2011

GE has received a contract to provide Masoneilan, LincolnLog and SteamForm modulating steam control valves and auxiliary systems to Southern Co.’s Mississippi Power Integrated Combined Cycle (IGCC) power plant in Kemper County, Mississippi, U.S.A.

Southern Co.’s order includes more than 50 separate turbine and process steam bypass valves, spray water control valves, pressure reducing valves and silencers. Masoneilan bypass valves will facilitate the start-up, shut-down and trip cycles of the steam turbines as well as provide process steam to and from the gasifier, and are necessary for the flexible operation of the plant in response to fluctuating power demand.

The 582 MW IGCC power plant, owned and operated by Mississippi Power, will use lignite coal to generate electricity. The coal is converted to syngas, which is used to fuel gas turbine-generators that drive downstream steam turbine-generators, GE said.

The valve and auxiliary systems are expected to be delivered this year, and the power plant is expected to be operational in 2014. The Masoneilan team will also offer continuing service and parts support for the bypass systems.
