At present, the electric power generated in coal-fired power stations accounts for about 25% of the total electric demand in Japan. The demand for steam coal is increasing all over the world. Almost all Japanese coal fired power stations utilize bituminous coal as fuel. From the viewpoint of preserving steam coal, it is important to diversify the type of coal used. In this article, coal combustion technology for pulverized low quality fuels, which are sub-bituminous coal with high moisture, low grindability coal and biomass to reduce CO2 emission, is explained.
