Abstract Chemical-looping combustion (CLC) is a highly efficient CO 2 separation technology with no direct contact between air and fuel. A metal oxide used as an oxygen carrier (OC) acts in dual fluidized bed tool supplies the fuel oxygen, which oxidation medium causes to H O. The use of solid fuels, especially biomass, focus current investigations. OC plays key role, because it must meet speci...

One of the major advantages SOFCs is their high fuel flexibility. Next to natural gas and hydrogen, which are today's most common fuels for SOFC-systems cell-/stack-testing respectively, various other applicable as well. In literature, a number promising results show that available propane, butane, ammonia, gasoline, diesel etc. can be applied. Here, performance an anode supported cell operated...

In this study, performance and combustion characteristics of dual fuel operations (biogas, biogas+hydrogen) were experimentally analyzed compared with corresponding baseline diesel in four-cylinder, common-rail engine without thermal barrier coated piston. Tests conducted at three different loads (50 Nm, 75 100 Nm) a constant speed 1750 min-1. Engine pistons Yttria Stabilized Zirconia material ...

ammonium carbonate and ammonium sulfate have been proposed and used as two new fuels for synthesizing gamma alumina nanoparticles. the prepared samples have been characterized by x-ray diffraction (xrd), 2 n  adsorption (bet) and transmission electron microscopy (tem). a comparison has been made between the properties of the nanoparticles synthesized by these two fuels and other conventional fu...

Bubble breakup and associated gaseous cavitation inception triggered by a single bubble injected into the flow of aviation fuel flowing in converging–diverging nozzle are characterized employing advanced computer vision (CV) algorithms. The obtained statistics from CV blob detection analysis provide unprecedented quantitative data non-intrusive imaging techniques reveal valuable insights regard...

Title of Document: Investigation of Colorless Distributed Combustion (CDC) with Swirl for Gas Turbine Application Ahmed Essam ElDin Khalil Hasan, PhD, 2013 Directed By: Dr. Ashwani K. Gupta Distinguished University Professor Department of Mechanical Engineering Colorless Distributed Combustion (CDC) with swirl is investigated for gas turbine engine applications due to its benefits for ultra-low...

Biomass is recognized to be the major potential source for energy production. Gasification enables conversion of these materials into combustible gas, mechanical and electrical power, synthetic fuels, and chemicals. In the present study, a model developed by us in our earlier study is used for predicting the steady-state composition and rate of reaction profiles for the reduction zone of the do...

UNLABELLED In 2001-2003, a team of researchers from the United States and China performed an independent, multidisciplinary review of China's National Improved Stove Program carried out since the 1980s. As part of a 3500-household survey, a subsample of 396 rural households were monitored for particulate matter less than 4 microm (PM(4)) in kitchens and living rooms over 24 h, of which 159 were...
