Abstract: The desulphurization technology of thermal power unit was expounded. Taking the environment protection management of the Yunnan Huadian Kunming Power Generation Corporation Limited as an example, the desulphurization environment protection management of the thermal power unit was discussed, which includes the operation management of the parameter indexes of the desulphurization system, the management and supervision of the CEMS in daily operation, the governing of the equipments of the desulphurization system and so on. Combining with the operation situation of the desulphurization system, the suggestion of the desulphurization environment protection management was put forward to ensure the safe, higheffective and economical operation of the desulphurization system.

Key words: flue gas desulphurization (FGD), wet FGD, continuous emission monitoring system (CEMS) for flue gas, management of environment protection
