Gasifier<br />
sorbent which removes most of the sulfur from<br />
the produced gas. A ceramic barrier filter<br />
removes all but a trace of particulates. Because<br />
the fuel gas is cleaned at high temperature, ther<br />
mal inefficiencies associated with cold gas<br />
cleanup are avoided. The cleaned coal gas is<br />
burned in a gas turbine which produces about<br />
60 percent of the plant power output. The rest of<br />
the power is produced in a steam-turbine genera<br />
tor operated on steam generated from gas tur<br />
bine exhaust.<br />
The gasifier vessel is expected to be ap<br />
proximately 15 feet in diameter and 74 feet in<br />
length, with a shipping weight of 1 70 tons. Desul<br />
furization will be accomplished by a combination<br />
of limestone fed to the gasifier and treatment of<br />

The General Electric 6FA combustion turbine<br />
selected is a scaled model of GE's 7FA machine.<br />
The 6FA with its 2,350F firing temperature and<br />
1,100F exhaust temperature enables SPPC to<br />
use a 950F/950 psia steam cycle design. This<br />
Improves overall plant cycle efficiency sig<br />
nificantly.<br />
Cost and Schedule<br />
The project is currently scheduled to start up late<br />
in 1996, and be in commercial operation by<br />
early<br />
1997. The total project cost is ap-<br />
