HEAT EXCHANGER FOR HIGH TEMPERATURE COLLECTION FROM DIRTY WARM LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger for warm heat collection from dirty warm liquid capable of avoiding a problem of pollution of a heat transfer surface by using a different kind of fluid to heat-transport between the dirty fluid and a solid metal heat exchanging surface by preventing direct contact of the dirty fluid and the solid metal heat exchanging surface. SOLUTION: The heat exchanger for warm heat collection from the dirty warm liquid is characterized by carrying out heat transport by evaporating volatile liquid at a part where the both liquid direct makes contact with each other by injecting the dirty warm liquid holding warm heat to a different kind of the volatile liquid higher in density which is reserved in a container.
