Large CFB power plant design and operating experience: Texas-New Mexico Power Company 150 MWe (net) CFB power plant
The first unit of the TNP One CFB power plant was successfully put on line by Texas-New Mexico Power Company (TNP) in Robertson County, Texas, US in 1990. Unit 2 came on line one year later. This grassroots plant fires Texas lignite. The two identical CFB units were each designed for 150 MWe net electrical generation. The units have operated at 155 MWe net for extended periods of time without modifications. The boilers have additional capacity but are limited by the balance of plant. The TNP One plant was awarded the Power Plant of the Year Award by Power magazine in 1991 advancing CFB technology in large generating facilities. The plant was designed for maximum fuel flexibility with guaranteed full load operation on either Texas lignite, western coal or natural gas. The plant has fired the following fuels, to date: lignite (base fuel), natural gas (0--100% with lignite), delayed petroleum coke (0--100% with lignite), plant generated waste oils (small amounts), oil filter fluff (small amounts) and a waste product of pelletized reflective tape. Future testing is planned to test burn shredded tires. While firing all fuels, the plant could attain full load and meet all environmentally permitted emissions without any boiler modifications or compromises in boiler efficiency. This high flexibility of the plant can be attributed to the two large fluidized bed heat exchangers (FBHEs) for steam temperature and combustor temperature control. The facility is a mine mouth operation burning the local Texas lignite. The delayed petroleum cokes fired originated from various supply sources from the Texas/Louisiana area.
