Heat Recovery Steam Generators (HRSG)


In 1998, TIWW entered into a licensing agreement with Nooter/Eriksen (N/E) to design and supply EOR type HRSG units for Cogeneration projects in Canada. N/E is a world leader in the design of Heat Recovery Steam Generators .

As a full technology licensee, TIWW is capable of, and responsible for, the entire mechanical and thermal design, utilizing N/E proprietary software. The complete resources of N/E's extensive world experience is available to TIWW on an as needed basis.

These units are custom designed to be installed behind Gas Turbines, taking the heat from the exhaust gas and exchanging it with produced water in the HRSG coils to generate approximately 80%+ quality steam. Using the Nooter/Eriksen proven technology processes, TIWW can design the HRSG requirements for any Gas Turbine. The EOR HRSG differs from the conventional HRSG in that it has individually controlled water/steam flow circuits, horizontal tubes and no steam/mud drums that allows operation with plant produced water.

TIWW's scope of supply includes all components from the turbine outlet to the tip of the HRSG exhaust stack on the combustion side and all high pressure piping from the owner supplied pumps through to the steam discharge valves. All instrumentation within these boundaries is included in our supply. High pressure fuel delivered to our skid edge is regulated down to the required levels for the multi-runner burner elements. 

All Safety controls, instrument valves and CSA approved shutdown hardware is shop assembled and delivered to site as modular components.

The EOR HRSG can operate both with and without duct firing as dictated by steam demands.
