Abstract: A combined cycle power plant utilizes an absorption heat transformer to improve plant efficiency. A heat recovery steam generator receives exhaust from a gas turbine and generates steam for input to a steam turbine. The heat recovery steam generator includes a low pressure economizer, an intermediate pressure economizer and a high pressure economizer. The absorption heat transformer is in fluid communication with the low pressure economizer. The absorption heat transformer includes a feed water circuit that draws exhaust water from the low pressure economizer for heating by the absorption heat transformer and directs heated water to at least one of the intermediate pressure economizer and the high pressure economizer.
