The Research On Technology And Plant Engineering Consultants Of The Steam Supply Reconstruction For Coal-Fired Power Units

The steam supply reconstruction for coal-fired power units can change the coal-fired power units as the cogeneration units, which conforms to the national policy of energy conservation and emissions reduction. The cogeneration realized the cascade utilization of energy, with significant economic benefit, social benefit and environmental benefit. The steam supply reconstruction not only makes the vitality of small thermal power unit, and eliminates some regional boiler rooms with high energy consumption, high pollution. Steam supply reconstruction get a good developmentand promotion at home and abroad.Taking HaiBoWan2x200MW condensing unit power plant as the research object, the steam supply reconstruction was studied in technology research and economical analysis.First, the national energy conservation and environmental protection policy and the development direction of thermal power unit was analyzed and successful cases for coal-fired power units at home and abroad was studied in this paper.Second, the cogeneration technology was deeply studied. The cogeneration unit characteristics of technology and economy index and energy consumption model were deeply studied, too. The features of the cogeneration units and thermoelectric production units was compared.At last, the steam supply reconstruction of the HaiBoWan2x200MW condensing unit power plant was deeply studied in this paper. The steam supply reconstruction technology wasdeeply studied. The design scheme, chemical water treatment, steam pipe laying and the technical measures of water supply facilities were analyzed in detail.The project management of the steam supply reconstruction was analyzed in detail. In addition, the analysis on the economy was made in this paper. The economic benefit and risk factors of steam supply improvement were carried on the thorough careful research.A conclusion was found in this paper, the steam supply reconstruction for coal-fired power units is not only technically feasible and economical,but also has the huge profits, also can get the support of national policy. The steam supply reconstruction of the HaiBoWan2×200MW condensing unit power plant provides a good example for others.
