This study aimed to explore the combustion kinetics of organic matter in Huadian oil shale using thermogravimetric analysis. Increases in particle size or heating rate shifted the combustion process to a higher temperature, because of mass transfer resistance and thermal hysteresis. An...

An energy analysis of solid oxide fuel cell (SOFC) power systems with gas recycles fed by natural gas is carried out. Simple SOFC system, SOFC power systems with anode and cathode gas recycle respectively and SOFC power system with both anode and cathode gas recycle are compared. Influences of...

GHG (Increasing greenhouse gas) emissions in China imposes enormous pressure on China’s government and society. The increasing GHG trend is primarily driven by the fast expansion of high energy-intensive sectors including the chemical industry. This study investigates energy consumption and...

As required by the Energy Policy Act of 2005, utility companies across the U.S. are offering TOU (time-of-use) based electricity demand response programs. The TOU rate gives consumers opportunities to manage their electricity bill by shifting use from on-peak periods to mid-peak and off-peak...

In this paper a highly efficient solar concentrating mirror is presented. A part of the aspherical cylinder's inner wall defined by a set of specific coefficients a2, a4, a6, a8, a10, a12, a14, a16 and C is used as reflective surfaces of concentrating mirror. Based on the particular aspherical...
