The role of coal cleaning in integrated environmental control
Coal cleaning is an effective means of improving coal quality to meet fuel specifications. Coal quality influences all aspects of power plant performance, particularly environmental control system design and operation, and therefore is significant in determining electricity costs. The strong dependence of environmental control costs on coal composition requires fuel selection and coal quality decisions support environmental control strategies. This paper summarizes how coal cleaning allows less complex and costly environmental controls to be applied. Changes in fuel composition due to, and the costs for, coal cleaning are first reviewed. Higher boiler efficiency possible through lower air heater gas exit temperature is then summarized. Finally, the potential of cleaned coal to reduce environmental control capital and operating costs is summarized.
