In this paper, the end loss effect of arbitrary oriented parabolic trough solar collectors (PTC) is analyzed and discussed, the methods to reduce or compensate the end loss effect by extending heat absorber tube, setting a fan-shaped end plane mirror (FS-EPM) at one end of PTC and inclining PTC...

The rapid growth of the Chinese economy has led to an acceleration of electricity demand, which has enjoyed an annual growth rate above 10% during the past 20 years. However, China’s coal-based resource endowment heavily influences its energy structure in the long term, which will result in...

We have studied the cement industry in China to determine the prospects for renovation and for building new facilities during the 1990s, and, in particular, the prospects for improved energy efficiency. The potential is good for renovating most vertical-kiln plants to improve their energy...

A novel Rankine power cycle which uses a mixture of three hydrocarbons as working fluid is proposed to utilize the cold energy in LNG (liquefied natural gas). Process simulations and composition optimization of four schemes for the cycle are carried out. The results show that while the cycle is...
