Efficient use of natural resources is an important part of China's energy industry to achieve sustainable development. The promotion of circulating fluidized bed (CFB) boilers is an important way to save coal and other resources from the source. This article first analyzes the connotation of resource benefits generated by CFB boilers. From the perspective of CFB technology used for low-calorific value coal recycling, coal recovery rate and sustainable development of coal resources (mainly coal can extend mining time), the resource benefits obtained by CFB are analyzed. The resource benefits obtained were analyzed. Second, based on the input-output nonlinear optimization theory, aiming at maximizing the resource benefits of CFB technology, constructing a CFB technology resource benefit nonlinear optimization model, measuring output benefits-added value, that is, the extension time of coal years and coal mining recovery rate increased value. Finally, based on the installed capacity data of China's CFB technology units from 1990 to 2015, the model designed two scenarios for China's future CFB technology development, and predicted China's 2020 CFB machine assembly capacity and power generation. On this basis, by analyzing the degree of coal resource conservation and the extension of the exploitable years, the model derives the resource benefits generated by CFB technology under different scenarios and the impact on the sustainable development of China's coal resources. These conclusions provide a quantitative basis for China's future CFB technology development. 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
