Various Applications of High-efficiency H-25 Gas Turbine

OVERVIEW: Growing concern about environmental problems caused by thermal power plants is making the reduction of CO2 through more efficient power generation and the reduction of NOx and other emissions a top priority. The deregulation of the electric power industry, meanwhile, is helping to expand the demand for medium-capacity, high-efficiency thermal power plants geared toward IPP (independent power producer) and PPS (power producer and supplier) operations. At the same time, high-speed, broadband communications and security and encryption technologies are being used to deploy low-cost, multi-function monitoring services. Against this background, Hitachi has been working to increase the efficiency of its H-25 gas turbine while developing diverse applications and solution services about it, and has recently delivered three units of a power-generation plant to the Goi Power Plant of Goi Coast Energy, Ltd. This is a single-shaft type combined-cycle plant incorporating a 25-ppm-class low-NOx combustor and applying a high-efficiency H-25 gas turbine. To operate and maintain this plant, Hitachi provides power-generation solution services using remote monitoring with high-speed Internet lines and a risk-management tool for power-generation businesses based on financial technology.
