HRSG (Heat Recovery Steam Generator)

HRSG is mainly used to recover heat from G/T exhaust in G/T combined cycle plant.
We have 3 kinds of HRSG systems :
  • - Vertical Gas Flow, Natural Circulation Type
  • - Vertical Gas Flow, Forced Circulation Type
  • - Horizontal Gas Flow, Natural Circulation Type

Mitsubishi HRSG has the following features:

-High Performance, High Reliability
Based on rich experience of HRSG (first HRSG in 1963, first vertical gas flow, natural circulation type HRSG in 1970),
performance of Mitsubishi HRSG has been optimized to the limit. Also, auxiliary power consumption is minimized.
-Highly Economical
Mitsubishi HRSG suits for module construction. Transportation and installation can be optimized.
-Easy Maintenance
In case of vertical gas flow type, as heating element is horizontal, no need of scaffold for maintenance.
