Abstract
An algorithm process for treating fly ash found in flue gas to prevent rapping reentrainment of fly ash particles comprising adding ammonia to the fly ash particles in a stoichometric amount of one part or somewhat less of ammonia to one part of sulfur trioxide, such that rapping reentrainment of fly ash particles in the flue gas is prevented. An algorithm is used to determine the amount of sulfur in the flue gas.
