Lime powder is an important desulfurizer for power plant desulfurization because it can effectively remove the sulfur dioxide given out by coal burning and make the given out gases meet national standard. But power plant desulfurization has finesses requirement to lime power and grinding machine can be chosen only after lime powder fineness is determined.How dose lime powder desulfurize for tail gas? Crushed lime powder are injected to best reactive temperature area by compressed air to make full contact and good reactive time between lime powder and smoke. The main component of lime powder is calcium carbonate (CaCO3),which will break down calcium oxide (Cao) and carbon dioxide(CO2)under high temperature and then calcium oxide reacts with sulfur dioxide with oxygen to form calcium sulfate...
