The purpose of the research is to verify the viability and the applicability of TPCT (two-phase closed thermosyphon) sucker Rod in cyclic steam stimulation for heavy oils. On the basis of the previous researches and the basic principles of TPCT, the laboratory experiment system was setup and the...

An OFA (over-fire air) program and matched measures supporting efficient-combustion are proposed for the FW (Foster Wheeler)-type down-fired boiler, where the OFA is supplied from the arches of the boiler. A gas/solid cold test was conducted at a scale of 1:15, using a two-dimensional laser...

Measurements were taken for a 600-MWe wall-fired pulverized-coal utility boiler that was retrofitted with centrally fuel rich swirl coal combustion burners and two levels of OFA (over-fire air) technology. Using various swirl air vane angle settings a three-component particle-dynamics anemometer...

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...

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...
