Steam Drums | Boiler Drum | Boiler Steam Drums -

2017-1-24 · There are two types of horizontal steam drums. One is the water tube steam drum and the other is a waste heat steam drum. Both types of steam drums have the primary and critical purpose of the mechanical phase separation of the water and steam mixture which flows from the Heat Recovery System Generator (HRSG) evaporator into the drum or fired boiler.
