Scr System

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.

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.

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.

Combined Cycle Power Plant

The combined cycle power plant is recognized as one of the best thermal power plant for its high efficiency and cleanliness. As the main component of the combined cycle power plant, the gas turbine is the key for improvement of the combined cycle power plant. The next generation G class gas turbine, with turbine inlet gas temperature in 1,500°C range has been developed by Mitsubishi Heavy Industries, Ltd. (MHI). Many advanced technologies; a high efficiency compressor, a steam cooled low NOx combustor, a high temperature and high efficiency turbine, etc., are employed to achieve high combined cycle performance. Actually, MHI has been accumulating the operating experiences of M501G (60Hz machine) a combined cycle verification plant in MHI Takasago, Japan, and achieving the high performance and reliability. Also, M701G (50Hz machine) has been accumulating the operating experience in Higashi Niigata Thermal Power Station of Tohoku Electric Power Co., Inc. in Japan. This paper describes the technical features of M501G/M701G, and up-to-date operating status of the combined cycle power plant in MHI Takasago, Japan.

Combined Cycle Power Plant

In 2003 the M501G at Mitsubishi’s in-house combined cycle power plant facility located at Takasago (T-Point) was upgraded. The upgrade was accomplished by replacing some of the existing hardware in the M501G gas turbine, for further improvements in output and heat rate. The verification testing at this power plant has been continuing with MHI’s latest upgraded combustor technology, that has successfully demonstrated NOx levels at 15ppm and 9ppm or lower emission levels in Mitsubishi’s G and F gas turbines, respectively. The upgraded M501G has been officially designated as the M501G1 gas turbine. This paper describes the upgraded hardware and the operating experience at the T-Point power plant.
