DESCRIPTION OF THE CO-GENERATION FACILITY
The CI Power PlantFacility is a combined cycle co-generation plant. The Facility consists of an aircraft derivative gas turbine generator (the General Electric LM-2500), an unfired heat recovery steam generator (HRSG), an extraction/condensing steam turbine generator, and auxiliary equipment.
The LM-2500 gas turbine is equipped with an evaporative cooler to reduce inlet air temperature and increase plant electrical output. It normally operates at maximum continuous rated power, burning 215.2 to 223.8 million Btu per hour (lower heating value (LHV)) of natural gas to drive a generator which produces 21,489 to 22,381 KW of electric power during the six Time Of Use periods established by the Southern California Edison Co. (SCE). Water injection is used to reduce NOx emissions to 42 parts per million dry volume-referenced at 15% 02 (ppmdv).
The gas turbine exhaust is directed to the HRSG to produce intermediate and high pressure steam. NOx emissions will be further reduced to 9 ppmdv through the use of a selective catalytic reduction, SCR, unit located in the HRSG. The high pressure steam (890 psig, 830°F) along with the intermediate pressure steam (250 psig, saturated) will be directed through the extraction steam turbine to generate additional electricity (approx. 6,500 to 7,000 KWe). As required, 150 psig saturated steam will be extracted from the steam turbine to supply 125 psig steam to the University Campus and 10-12 psig steam will be extracted to run the cogeneration facility's deaerator. The remainder of the steam will be routed completely through the steam turbine, exiting at sub-atmospheric conditions. This exhaust steam will be condensed using an air cooled condenser and routed to the deaerator along with makeup water and Campus condensate return to complete the steam cycle.
Based on the anticipated steam flow rates supplied to the CSH, the Facility will generate 27,162 to 27,921 KW net electric capacity. The system is expected to operate for 6,875 hours per year based on 129 hours of scheduled outages, 258 hours of unscheduled outages (system availability of 95%), and 1,498 hours of scheduled full curtailment due to SCE operations dispatching.
