Heat Recovery Steam Generators (HRSG), for gas turbines in single and-or combined cycles and cogeneration plants.
The DELTA waste heat boiler, with a standarized modular design that fits most high-temperature flue gas heat recovery applications without custom design extra costs. The unique DELTA design offers eight different gas inlet-outlet arrangements and 60 sizes which to date are in operation downstream gas turbines with power output ranging from 1 to 25 MW.
The DELTA features a natural circulation design through the water-tube selection, promoted by unheated downcomers. To greatly extend the heating sufaces of the water tubes, serrated fins are continuously welded to the tube walls. Together with the special two-pass gas flow baffle system and the extended heating surfaces. DELTA is able to use longer and fewer tubes, and higher static head to assure better circulation.
Main characteristics of DELTA heat recovery steam generator:
The DELTA watertube heat recovery boiler is widely recognised as an industry standard for small to medium gas turbine exhaust applications. It has also found extensive use in process furnace, refinery heater and fume incinerator applications.
