Case Study #1 247
development and performance improvement. The Piñon Pine project
represents the next step in demonstrating this technology on a commercial
scale. A unique feature of this IGCC application is the ability
of the GE MS6001FA compressor to deliver the high extraction flows
required to supply an air-blown gasifier. While the turbo-machinery
is unchanged, the combustion design is modified, based on experience
gained from previous “F” class machines that have been integrated
into IGCC applications. The combustion system is flexible and can
operate efficiently on a variety of fuels including the low Btu syngas
and natural gas to be used at Piñon Pine. The highly efficient “F”
technology MS6001FA confers excellent combined cycle performance.
Because of its physical design, the MS6001FA gives a logical, economical
combined cycle powerplant arrangement. Additionally, the
air-blown gasifier, with hot gas clean-up, allows significant plant simplification
and improvement in overall plant efficiency. This project
will demonstrate reduced NO x
and SO x
emissions resulting from the
hot gas clean-up technology.
