Abstract
An integrated steam-ammonia power cycle is disclosed which achieves a close match to a glide heat source such as exhaust from a gas turbine, and which also eliminates sub-atmospheric pressure operation. With reference to FIG., the exhaust heats in sequence steam superheater; steam boiler; feedwater preheaterplus ammonia superheater; and ammonia preheater. Steam is expanded to at least 17 psia in turbine, then condensed to boil ammonia in boiler. Superheated ammonia is expanded in turbine, and condensed in condenser. Feed ammonia is preheated in at least two parallel preheaters.
