Abstract

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.
