Ash recycling system and ash recycling method

摘要

Problem: the ash obtained by burning solid combustion such as coal can be readily reused on the spot.First, the exhaust gas is cooled by the first tank 2 in order to adsorb sulfur oxide from the exhaust gas combusted by coal.At this time, water which exceeds the saturated vapor amount is recovered by the water recovery unit 21, and the exhaust gas is adsorbed to the adsorbent by the second tank 6.On the other hand, limestone is also supplied to the combustion furnace 10, and calcium oxide and calcium sulfide are recovered together with coal ash, and the water recovered by the water recovery portion 21 is mixed to produce cement.Diagram
