Coal combustion systems with emissions control and fly ash beneficiation and methods thereof

A system for controlling emissions with ammonia recovery and fly ash beneficiation, the system comprising:

• a first ammonia delivery system connected to an exhaust system to introduce ammonia that reacts with at least a portion of sulfur trioxides in an exhaust emission and results in at least one or more ammoniated compounds;
• a precipitator system that precipitates at a least a portion of fly ash particles and the ammoniated compounds in the exhaust emission;
• a beneficiation system that beneficiates at least the precipitated fly ash particles;
• a recovery system that mixes at least a portion of the beneficiated fly ash particles which are heated with the precipitated ammoniated compounds to recover at least a portion of the ammonia;
• and
• a resupply system that supplies the recovered ammonia to the first ammonia delivery system

A method for making a system for controlling emissions with ammonia recovery and fly ash beneficiation, the method comprising:

• connecting a first ammonia delivery system to an exhaust system, the first ammonia delivery system introduces ammonia that reacts with at least a portion of sulfur trioxides in an exhaust emission and results in at least one or more ammoniated compounds;
• connecting a precipitator system to the exhaust system, the precipitator system precipitates at a least a portion of fly ash particles and the ammoniated compounds in the exhaust emission;
• connecting a recovery system to the precipitator system to receive the precipitated fly ash particles;
• connecting a beneficiation system to the recovery system, the beneficiation system beneficiates at least the precipitated fly ash particles, wherein at least a portion of the beneficiated fly ash particles which are heated are provided to and mixed with the precipitated ammoniated compounds in the recovery system to recover at least a portion of the ammonia;
• and
• connecting a resupply system to the recovery system, the resupply system supplies the recovered ammonia to the first ammonia delivery system.
