Heat Recovery Steam Generators
& Once Through Steam Generators
As heat transfer specialists BIH have extensive experience of thermal recovery systems and have used that capability to extend their product range from WHRUs to HRSGs & OTSGs.
HRSGs are used to recover heat from gas turbines or other hot process streams and converts that energy into useful power by raising steam at a sufficiently high pressure to be utilised in a steam turbine. This recovered heat increases the overall efficiency of the cycle and contributes to a lower Carbon foot print for the installation.
HRSGs are regularly used in the power generation industry to extract maximum value from the molecule and to optimise cycle efficiency. They are increasingly being used on process plant in order to increase value and promote greater self-reliance by providing additional captive power generation.
In this critical piece of equipment, providing the thermodynamic bridge between exhaust gases and valuable power, BIH are able to optimise each component comprising the economizer, evaporator, superheater and water preheater to ensure the best process and thermodynamic response taking into account all variables
Additional power can be extracted through supplementary firing on which BIH have a significant and successful track record.
BIH apply its extensive experience to the utility heating market and design, manufacture and supply of fired and unfired Heat Recovery Steam Generators (HRSG’s).
HRSGs operating in combined cycle with Gas Turbines and increase overall plant efficiency making a significant contribution to reducing the CO2 per Kw/hr.
Produced steam can be used for process heat and power generation in steam turbines.
Once Through Steam Generators (OTSGs) are suitable for higher steam pressure and temperature applications. It eliminates the use of the circulation system along with the steam drum.
Once Through Steam Generators
When plant constraints do not allow for conventional drum-based natural circulation steam generators BIH can offer once through steam generation units (OTSGs) to overcome weight and plot space limitations. The compact vertical exhaust arrangement lends itself to offshore applications and the absence of the of heavy walled steam drums allows for rapid start-up rates from cold.
