Heat Recovery Steam Generators are used to recover waste heat from the exhaust of gas turbines, boosting efficiency from a range of 35% to 40% in a simple cycle (also known as open cycle) mode to a range of 55% to 60% in a combined cycle mode. The steam generated by the HRSG can be used for process heating or generating electricity in a steam turbine. Such units are installed on gas turbines ranging from below 1 MW up to 320 MW.
These units are offered with features such as horizontal/vertical design, natural/forced circulation, triple pressure levels with reheat option, supplementary and fresh air firing mode with automatic changeover, bidrum/single drum.

The HRSGs incorporate latest advances in thermal technology, offering benefits such as multiple pressure levels and unprecedented reliability. The growing number of our HRSGs installations is a testimony to their importance in ‘clean energy’ solutions.
