摘要

重庆发电厂2×220 MW机组脱硫装置至今已运行4年多

设备投入率、石膏产量逐年上升

但随着我国燃煤市场的变化

实际燃煤含硫量及入口原烟气SO2浓度大大超过设计值

给装置运行带来了如脱硫效率下降

副产品石膏品质下降

辅助系统腐蚀、磨损、泄漏、结垢加剧等问题。对此

通过采取配煤及运行等措施

取得了良好效果。当机组满负荷且原烟气SO2浓度在≤10 000 mg/m3时

脱硫效率基本能达95%

石膏品质也能满足控制指标

达到市场要求。

Abstract

The desulfuration system for 2×220 MW units in Chongqing Power Plant has already put into operation for more than four years up to now

the in-service ratio of equipment and the output of gypsum have been increasing year after year

however

along with the change of fuel coal market in our country

the sulfer content in practical fuel coal and SO

concentration in original flue gas all greatly exceed the designed values

many problems

such as decrease of desulfuration efficiency

reduce of quality for byproduct gypsum

corrosion and wornout in auxiliary system

and intensification of leakage and scaling etc.

have occurred in operation of said system.After using blend coal and operation measures

good result has been obtained.In case the unit is with full load

and the SO

concentration in original flue gas ≤10 000 mg/m

the desulfuration efficiency

can basically reach 95%

the quality of gypsum can also satisfy the controlled indices

reaching requirements of the market.
