Flue Gas Conditioning Systems
In response to clean air regulations, power generating utilities with
coal-fired boilers are switching to low-sulfur coal to reduce sulfur
dioxide and sulfur trioxide emissions that contribute to acid rain. But
lower sulfur trioxide levels in boiler flue gases make fly ash more resistant
to collection in the precipitator.
