Experimental Study on Boiler Operating Conditions on the Efficiency of Circulating Fluidize Bed Flue Gas Desulphurization
In order to resolve the problem that changes in boiler operating conditions affecting the efficiency of circulating fluidize bed flue gas desulphurization, we designed and built an experiment table for the study of the operating parameters on desulphurizition efficiency. The result is: the best desulphurization tower entrance temperature range of the gas is 117 - 124 ℃ , and the best desulphurization tower exit temperature range of the gas is 74 -75 ℃. Under this temperature, the best water spray is 1.17 -1.25m3 /h. In this condition, the desulphurization efficiency can reach 90％; the higher desulphurization tower entrance SO2 density is, the harder desulphurization efficiency can be reached; when the inject water is steady, the desulphurization efficiency will decrease by the boiler load increase.
