RE-VAP series

Heat recovery steam generators

RE-VAP-type recovery steam generators are the best solution for high-efficiency cogeneration: of fully welded construction, they allow the abrupt load variations typical of many industrial processes to be accommodated, guaranteeing continuity of production, together with the maximum exchange efficiency guaranteed by the spiroidal fin tube bundles.

Their modular tube bank design allows them to be adapted to the layout requirements of thermal power plants; the possibility of integrating supplementary combustion and fresh air system in case of unavailability of the primary source extend their potential, availability and production flexibility.
All generators can be equipped with ECO2 low-temperature hot water production bank to maximize energy recovery.

The generators rest on a load-bearing base that allows load distribution to simplify civil works for installation.

To complete the supply, we offer turnkey construction and installation of the entire flue gas line to the top of the evacuation stack from the primary generator exhaust flange, such as: gas turbines, endothermic engines, furnaces, process flue gas exhausts.
