The new power policy and new power market environment of China is analyzed, the viewpoint on selecting energy-saving, environment-friendly and sustainable clean power technologies for Chinese power industry is put forward, as an reference for both theoretical research and practical operation.

By using three-dimensional numerical simulation techniques together with the Eulerian-Eulerian method,a numerical simulation research of the gas-solid phase flows within the gas-solid injector which is the key element of clean coal power generation system is performed in this paper.
