A Closer Look at PRB Coal

A Closer Look at PRB Coal

Lowsulfur coals such as PRB coal increase the fly ash resistivity, resulting in lower electrostatic precipitator (ESP) performance. One way to overcome this is by increasing the size of the ESP, but this approach is expensive and time consuming, requiring longer outage periods. Alternatively, chemicals such as ammonia can be injected into the flue gas stream to reduce the resistivity ...
