Plant Description -
Currently decommissioned, the cogeneration plant
was located at California's Correctional Training Facility
(CTF) in Soledad, California and
provided steam and electricity to the facility.
The 2200 kW plant was powered by two turbocharged and intercooled 12 cylinder gas engines. The two Waukesha model L7042 engines utilized natural gas as the primary fuel. Domestic hot water
was provided via heat exchangers in the Waukesha intercooler/lube oil systems. Low pressure (15 psig) steam
was produced in the engines' ebullient jacket cooling system. Two Riley Beaird heat recovery boilers captured thermal energy from the exhaust of each
engine-generator to produced 120 psig steam. The cogeneration plant
provided 80% of the 6000 lb/hr base steam load. Auxiliary boilers supplemented the cogen units to satisfy the CTF's maximum steam demand of 45,000 lb/hr.
The cogeneration plant was designed by Dewante and Stonewell and constructed by Amos and Andrews. The units started up in late 1985. CTF staff operate the facility.
IPT Services Provided - International Power Technology (IPT) was contracted in 1991 to take over management of all aspects of the cogeneration facility. IPT's initial task was to plan, schedule, and implement the plant's complete rehabilitation and overhaul. Engines, steam generators, controls, and instruments have been reconditioned with the objective of restoring optimal thermodynamic and economic performance. The plant resumed operation in late 1991. IPT
provided operations, maintenance
and management support for the
facility up to its
decommissioning in late 1996.
IPT Experience - IPT is an energy company offering a broad range of services to parties interested in cogeneration, independent power, and thermal energy production. IPT activities can be tailored to the specific needs of a facility.
IPT provides services to more than a dozen plants comprising over
72 MW of generation equipment. In addition, IPT provides plant design consulting, controls integration, and startup services to cogeneration facilities in North America, Europe, Japan and Australia.
