A combined-cycle power system based on oxygen-blown coal partial gasification is proposed to promote the performance and reduce the investment of conventional integrated gasification combined cycle (IGCC) power system. The proposed power system combines the characteristics of IGCC and...

In this paper, both conventional and advanced exergy analyses were conducted to a large-scale ultra-supercritical coal-fired power plant. The objectives of the conventional one are to compare the exergetic performances of different components, to identify and quantify the sites with the largest...

Simultaneous antireflective and self-cleaning properties have been realized by depositing double-layered SiO2–TiO2 coatings onto glass substrates using a combined sol–gel dip-coating process in which the two oxide layers were deposited in succession. The first layer is composed of a hybrid...

An increasing number of tower-type boilers have been applied to ultra-supercritical power plants because of the simple design of the membrane walls and the smooth increase in temperature of such boilers. Nevertheless, the significant height and long steam pipelines of this boiler type will...

We have designed a solar thermoelectric cogenerator (STECG), which can supply electric power and heat simultaneously, by adding thermoelectric modules to the heat pipe in evacuated tubular solar collectors. A pilot experiment shows that the STECG can generate 0.19kWh of electrical energy and...

Coal-fired power plants in China consume nearly half of available coals, and the resulting CO2 emissions cover over 40% of total national emissions. Therefore, reducing the energy expenditure of coal-fired power plants is of great significance to China’s energy security and greenhouse gas...
