Waste heat recovery system

摘要

In one embodiment, a waste heat recovery system (10) includes a Rankine cycle system (14) that circulates a working fluid that absorbs heat from exhaust gas. The Rankine cycle system (14) includes an evaporator (36) that may transfer sensible heat from the exhaust gas to the working fluid to produce cooled exhaust gas. The Rankine cycle system (14) also includes an economizer (30) that may transfer latent heat from the exhaust gas to the working fluid. The economizer (30) is a carbon steel heat exchanger with a corrosion resistant coating (52).
