발전기 냉각용 On-site 수소 생산 시스템 적용연구
문전수,이재근,박필양,박경일 한국수소및신에너지학회 2009 한국수소 및 신에너지학회논문집 Vol.20 No.5
A hydrogen cooling method is used in a power generator for removing the unnecessary heat due to the windage loss of a rotor and the joule heat of a stator. A MEA (Membrane Electrolyte Assembly) hydrogen generator has been developed and applied as a hydrogen supplying system for the cooling of a 350MW power generator. As a field application result, the average potential of eleven cells and the voltage efficiency were measured 2.26V/cell and 65.4% (Higher Heating Value) respectively at the hydrogen pressure of 6 Bar, the hydrogen flow rate of 9.1L/min, and the current of 150A.
발전소 냉각탑 시스템에서의 High C. O. C. 운전에 대한 연구

Common chemical treatment programs have been developed through pilot tests and field application tests for the high cycles of concentration (C.O.C.) operation in cooling tower systems of combined thermal power plants. The application of common chemical treatment programs, optimized for the high cycle operation, could save the make-up water of about 25,000 ton/day and reduce the inhibitor chemical cost significantly in the cooling tower systems of combined thermal power plants.
