A better understanding of CO2 emission trends caused by domestic consumption (referred to as the carbon footprint) in China, especially in the context of changes in consumption and production patterns triggered by economic development in recent years, is important to develop effective approaches...

Oxy-coal combustion produces a combustion environment that contains large amounts of CO2, H2O compared to conventional air combustion. Silica (SiO2) is a major component of the mineral impurities in coal and the vaporization of silicon containing species controls the initial phase of formation...

Little work has been performed on the importance of sodium and its occurrence in coal to PM2.5 (particles less than 2.5μm in aerodynamic diameter) reduction by kaolin during O2/N2 combustion and O2/CO2 combustion at high temperatures. In this study, the combustion experiment of a treated...

The continuous high-purity hydrogen production by the enhanced-sorption chemical looping steam reforming of glycerol based on redox reactions integrated with in situ CO2 removal has been experimentally studied. The process was carried out by a flow of catalyst and sorbent mixture using two...

A kilowatt-sized rolling-piston expander is proposed for low-temperature Organic Rankine Cycle power generation system. The main purpose of this paper is to conduct a dynamic test of the proposed expander. A low-temperature ORC system using R245fa as working fluid is established for the...

An experimental study is conducted to investigate the performance of a low-temperature solar recuperative Rankine cycle system using working fluid R245fa. The experimental setup consisted of typical Rankine cycle components, such as throttling valves, working fluid pumps, air cooled condensers,...

The paper presents an on site experimental study of a low-temperature solar Rankine cycle system for power generation. The cycle performances of pure fluid M1 (R245fa) and zeotropic mixtures M2 (R245fa/R152a, 0.9/0.1) and M3 (R245fa/R152a, 0.7/0.3) are compared, respectively, based on the...

In this study, an interval full-infinite mixed-integer municipal-scale energy model (IFMI-MEM) is developed for planning energy systems of Beijing. IFMI-MEM is based on an integration of existing interval-parameter programming (IPP), mixed-integer linear programming (MILP) and full-infinite...

HCCI combustion can substantially reduce NOx and soot emissions of diesel engines. However it is hard for diesel HCCI to obtain the same level of fuel economy as traditional diesel engines. This paper presents a way to improve the fuel economy of diesel HCCI by adopting Integrated Starter...

HCCI (Homogeneous Charge Compression Ignition) combustion has the potential to significantly reduce NOx and PM emission of diesel engines due to its nature of even mixture and low temperature combustion. This combustion mode is only applicable in part load and low speed area so far. This range...
