The validated numerical method was employed to analyze pressure effects on the combustor emissions such as different mixing levels and extra reactant addition. The model combustor, fueled with 10 MJ... Thermodynamic comparison and efficiency enhancement mechanism of coal to alte...   　　Coal to alternative fuels is an important path to enforce energy security and to provide clean energy. In this paper, we use exergy analysis and energy utilization diagram (EUD) methods to disclose the internal reasons for performance differences in typical coal to alternative fuel processes. ASPEN plus softwar... Experimental study on the melting and solidification behavior of erythritol i...   　　An experimental study on a vertical shell-and-tube latent heat thermal storage unit with erythritol as storage media and air as heat transfer fluid (HTF) is conducted to evaluate the thermal behavior and heat transfer performance of the unit. The thermophysical properties of erythritol, such as melting temperat... Thermodynamic performance of a mid-temperature solar fuel system for cooling,...   　　Solar thermal fuel is a promising approach of solar energy utilization, in which concentrating solar energy can drive the hydrocarbon fuel decomposition or steam reforming to produce hydrogen or syngas for generating power through heat engine. In the present, most of solar thermal fuel processes have employed s... Effects of wall temperature on slagging and ash deposition of Zhundong   　　Zhundong coal with a large reserve is faced severe ash-related problems including slagging and fouling during pulverized-coal boiler combustion. The gasification in circulating fluidized bed is a good way to use Zhundong coal due to the low reaction temperature, while it is unknown for the slagging and ash depo... Experimental investigation on flow characteristics in open rectangular microg...   　　In this paper, flow characteristics in open rectangular microgrooves were investigated by micro-PIV. Liquid cross-sectional areas and central thickness of the liquid film of the meniscus along the axial direction of the microgroove were both studied. The results show that there is a ‘dead zone’ near the end o... Investigations of leakage mechanisms and its influences on a micro swing engi...   　　Considering rarefaction effects, this paper investigated mechanisms of the clearance leakage and its influences on a micro swing engine for the micro power generation by employing three different flow models named as discrete velocity direction (DVD) model, Navier-Stokes equations with slip boundary conditions ... Performance of a gas cooled molten salt heat exchanger   　　An experimental system has been built to research the heat transfer characteristics of gas cooled molten salt heat exchangers. Based on the system, a prototype tube-and-shell gas cooled molten salt heat exchanger was experimentally investigated. A nitrate salt mixture (NaNO3-KNO3-NaNO2) was chosen as the hot fl... A solar thermochemical fuel production system integrated with fossil fuel hea...   　　Thermochemical cycling (TC) is a promising means of converting solar energy and storing it in chemical fuels. Isothermal solar TC has the potential of achieving high solar-to-fuel efficiencies contingent on effective gas-phase heat recovery at high temperatures. We propose an approach of simultaneously recoveri... Comparative exergy analysis of chemical looping combustion thermally coupled ...   　　This paper investigates the benefits of chemical looping combustion (CLC) thermally coupled with steam methane reforming (SMR) process (CLC-SMR) over conventional SMR process by means of exergy analysis. The conventional combustor of SMR is replaced by employing CLC system in order to achieve cleaner production...   14 Page(s)   FirstPrev12345NextFinal
