Utilizing the global DEA (data envelopment analysis), this paper analyzes China's energy efficiency from both static and dynamic perspectives based on China's provincial panel data for the period of 2001–2010. We present the evolution of energy efficiency in China from 2001 to 2010, and...

Down-fired boilers currently suffer from a number of different issues including high levels of fly ash in the combustible matter, serious slagging and a high level of NOx emissions. In this study, the combustion system of a down-fired 350 MWe supercritical utility boiler was designed with...

An optimization approach based on greedy algorithm for optimization of wind farm micro-siting is presented. The key of optimizing wind farm micro-siting is the fast and accurate evaluation of the wake flow interactions of wind turbines. The virtual particle model is employed for wake flow...

Wind farm micro-siting is to determine the optimal positions of wind turbines within the wind farm, with the target of maximizing total power output or profit. This paper studies the performance of the lazy greedy algorithm on optimization of wind turbine positions above complex terrain. Instead...
