General boiler combustion ash is two parts, part of the flue gas to the end of the boiler exhaust by the dust collector, in addition to conventional fly ash; another part of the slag from the bottom of the furnace cooling after the discharge, conventional said slag. Different types of boilers are different in proportion to large power plants, for example, about 90% of fly ash, slag is about 10%
General 5000kcal/kg coal ash in about 20%. If you refer to the coal cinder is the ash after the combustion of coal, that is 200kg.
