1050MW超超临界燃煤发电机组湿法脱硫系统运行优化研究

Research on Operation Optimization of Wet Flue Gas Desulfurization System of 1050MW Ultra-Supercritical Coal-Fred Power Generator Set

针对某1050MW超超临界机组脱硫系统,分别研究了浆液循环泵组合方式、浆液pH、吸收塔液位对机组脱硫系统的影响。浆液循环泵组合选择BC最优,最佳浆液pH值为5.50~5.60,最佳吸收塔液位为8.00m^9.00m。

Aiming at the desulfurization system of a 1050MW ultra - supercritical unit,the effects of slurry circulation pump combination mode,slurry pH and absorption column liquid level on the desulfurization system of the generator unit are studied.The selection of BC for slurry circulation pump combination mode is optimal,the optimum slurry pH is 5.50 ~5.60,and the optimal absorption column liquid level is 8.00m ~9.00m.
