Abstract
Design of the first “300MW Circulating Fluidized Bed (CFB) boiler+limestone/gypsum wet Flue Gas Desulphurization (FGD) system” in the world is introduced, operating parameters of the boiler and FGD system are analyzed. The operating bed temperature is higher than 940°C, efficiency of the boiler is more than 93.5%. In the mean time, SO2 remove efficiency is higher than 95%, and 65% dust remove efficiency is gotten in the FGD system. Practice showed that deep desulphurization and deNOx of CFB boiler has higher SO2 remove efficiency at lower Ca/S ratio compared with traditional inner desulphurization mode, it can meet more and more rigid environmental protection emission standard, and is suitable to more fuels. Deep desulphurization and deNOx of CFB boiler can also realize high temperature CFB boiler which doesn’t aim to inner desulphurization and low NOx emission, and benefits to low-grade, high sulfur content fuels. Research of deep desulphurization and deNOx should be a developing direction for large capacity CFB boiler.
