The design, installation, commissioning and operation of a fogging system for a large 655 MW combined cycle power plant is described. Technical details and practical installation issues are discussed. Special considerations as to how the fogging system could help in the augmentation of power during high temperature and low frequency operation of the gas turbine is discussed. Finally a discussion is made regarding the importance of inlet filtration and the proper selection of blade coatings.

The Medway Project is a 660 MW combined cycle power plant, which employs two of the world’s largest advanced technology MS9001FA combustion turbine generators and an advanced design reheat steam turbine generator in a power plant system designed for high reliability and efficiency. This paper discusses the power plant system optimization and design, including thermodynamic cycle selection, equipment arrangement, and system operation. The design of the MS9001FA combustion turbine generator and the steam turbine generator, including tailoring for the specific application conditions, is discussed.

Residual Fuel Oil

This paper presents and discusses the successful operating experience and the issues related to burning low sulphur waxy residual (LSWR) fuel oil at the 507 MW IPP Daesan Combined Cycle Power Plant. The power plant was built and is operated by Hyundai Heavy Industries (HHI). It comprises four Siemens-Westinghouse 501D5 engines, each with a heat recovery boiler including supplementary firing and one steam turbine. This plant, commissioned in 1997, is designed to burn LSWR fuel oil. LSWR fuel oil was selected because of the lower fuel cost as compared to LNG and other liquid fuels available in Korea. By adding a combustion improver to the LSWR fuel oil it is possible for HHI to comply with the tight Korean environmental regulations, despite the tendency for heavy smoke and particulate emissions when burning this type of fuel oil. The successful operating experience, availability, reliability and performance achieved in Daesan, as well as the commercial viability (which by far offsets the additional capital expenditure and the additional related O&M costs) demonstrate that LSWR fuel oil firing in heavy duty gas turbines is rewarding. This is especially important in view of the growing disposal problems of residuals at refineries around the world.

Over three years of successful operating experience with a dry low NOx combustor and SCR system used in a combined cycle power plant of a Japanese utility is presented. The dry low NOx combustor with pre-mix fuel nozzles was verified by field test at a NOx level of 65 ppm. The SCP system has been operated with an efficiency between 30% and 90%, and shows no degradation in 20,000 hours operation.
