Recently, the abolition policy for coal-fired power plant has been established in KOREA, because they are regarded as the main culprits for the emission of greenhouse gases, fine dusts and nitrogen oxides. But it is expected to cause a huge loss in terms of economical and stable electric energy supply. Therefore the feasibility of the hot wind box repowering method to improve the environmentally friendly as well as high efficiency performance of the aged coal fired power plant was studied in this paper. This method combines the existing boiler with an additional gas turbine in the range of about 30 to 55% of the power output of the existing power plant, and the gas turbine exhaust gas is used as combustion air of existing boiler, and then flue gas of boiler is recovered by heating the feed water. The effect of applying this method is expected to be approximately 7%p increase in electric efficiency, 35% increase in power output, 50% reduction in coal use, 30% reduction in CO₂, and 41% reduction in dust and sulfur dioxide emission.
