'SCOPE OF MANUAL, manual describes the operation and maintenance of a Nooter/Eriksen Recovery Steam Generator (HRSG) Purpose 'This manual should be use - bo familiarize personnel with the equipment, not as a training manual. - as a guideline for operating and maintaining the equipnent. Baseload operation was normal for earlier HRSGs, but today's deregulated electric power market imposes that many new large HRSGs cycle or operate in flexible duty. The relatively simple design and less severe operating conditions than in radiant boilers running with coal or oil create a more benign environment for the HRSG heat exchanger tubes. Heat recovery steam generation. The HRSG recovers heat from the gas turbine exhaust to generate steam at temperatures up to ~°C and pressures of MPa. Although SC systems have been developed, heat-recovery steam generation is most commonly applied under subcritical conditions.

SCOPE OF MANUAL This manual describes the operation and maintenance of a Nooter/Eriksen Heat Recovery Steam Generator (HRSG). Purpose This manual should be used: to familiarize personnel with the equipment, not as a training manual.-as a guideline for operating and maintaining the equipment.-as a reference list to define the Nooter/Eriksen scope of supply.-as an outline in helping to develop an extensive, site-specific operation and maintenance plan for the entire HRSG system. The manual. related cost and, at the same time, contributes to the resolution of the greenhouse effect. Heat Recovery Steam Generators are key components in the combined cycle. Starting from the early 90’s, we began developing our proprietary HRSG design for: Horizontal gas path, natural circulation, cold casing and top supported HRSG. cycling operation or at least put a monitoring program to gage the effect of cycling. A program detailing how to modify or monitor the existing units is also described. TYPICAL COMBINED CYCLE HRSG A typical Combined Cycle HRSG produces steam at three pressure levels plus steam reheat. The auxiliary firing through a duct burner is.
