我国大型循环流化床锅炉机组运行现状 总被引:3,自引:0,他引:3
循环流化床锅炉因其燃料适应性广、负荷调节性强及环保性能优良等特性在我国得到了快速发展。经过短短的十几年,我国已是世界上装机数量最多、装机容量最大的国家。目前我国循环流化床锅炉机组的总装机容量已经超过了90 000MW,其中仅300MW级循环流化床锅炉机组已经投运40多台,在建与拟在建的300MW循环流化床锅炉机组超过了70台。通过对我国300 MW级循环流化床锅炉机组2008~2010年来的运行数据的调查,对机组的可靠性、经济性以及环保性作了全面的总结与分析,并与同等级的煤粉锅炉机组进行了比较。能够对今后更大型机组的设计以及运行提供较好的参考,甚至对我国循环流化床行业今后的发展起到一定的指导作用。 相似文献

The supercritical circulating fluidized bed (CFB) boiler, which combines the advantages of CFB combustion with low cost emission control and supercritical steam cycle with high efficiency of coal energy, is believed to be the future of CFB combustion technology. It is also of greatest importance for low rank coal utilization in China. Different from the supercritical pulverized coal boiler that has been developed more than 50 years, the supercritical CFB boiler is still a new one which requires further investigation. Without any precedentor engineering reference, Chinese researchers have conducted fundamental research, development, design of the supercritical CFB boilers independently. The design theory and key technology for supercritical CFB boiler were proposed. Key components and novel structures were invented. The first 600 MWe supercritical CFB boiler and its auxiliaries were successfully developed and demonstrated in Baima Power Plant, Shenhua Group as well as the simulator, control technology, installation technology, commissioning technology, system integration and operation technology. Compared with the 460 MWe supercritical CFB in Poland, developed in the same period and the only other supercritical one of commercial running in the word beside Baima, the 600 MWe one in Baima has a better performance. Besides, supercritical CFB boilers of 350 MWe have been developed and widely commercialized in China. In this paper, the updated progress of 660 MWe ultra-supercritical CFB boilers under development is introduced. 相似文献

Clean coal fluidized-bed technology in Poland 总被引:11,自引:0,他引:11

The use of a circulating fluidized-bed (CFB) for power generation is a rapidly growing technology in Poland. The ability of CFBs to burn a wide variety of fuels, while meeting strict emission-control regulations, makes them an ideal choice for burning such fuels as high-sulfur coal, lignite, peat, oil, sludge, petroleum coke, gas and wastes. All these fuels are burned cleanly and economically in CFB boilers without the need for complex scrubbers, catalytic systems or other costly chemical clean-up systems. Presently 19 CFB units are in operation or under construction in Poland; utilizing a wide variety of fuels and wastes. On the basis of gathered performance data, the CFB units met and significantly satisfied all the emission levels. The paper presents the boiler design parameters, design arrangement and specific unique design features of the CFB boilers. A particular concern with the CFB boiler is the low rank brown-coal and the large furnace which had to fit into the limited space of the existing plant. Environmental performances of large-scale CFB boilers are demonstrated. Special emphasis is placed on the experience gained with the largest CFB boilers which have been in operation for more than 4 years. 相似文献
