Waste Heat Recovery System and Method Thereof

Abstract

A waste heat recovery system comprises a steam generator, a processor, a first heat exchanger, and a second heat exchanger. The steam generator generates an original steam using water. The first heat exchanger condensates the first steam and emit water and a second steam from the processor. The second heat exchanger condensates the second steam from the first heat exchanger. The second heat exchanger condensates the second steam from the first heat exchanger leaving water only. The water from the first heat exchanger and the second heat exchanger may be guided into the steam generator or into the first heat exchanger. The second heat exchanger comprises one or more pressure relief valve. The pressure relief valve operates when inner pressure of the second heat exchanger exceeds above a predetermined value.
