Interest in fuel cells in recent years has promoted the development of hydrogen sources. Methane is an optimal fuel for hydrogen production due to its rich resource and its high ratio of hydrogen to carbon. Computational fluid dynamics (CFD) combined with detailed chemical kinetics was employed to model the super adiabatic combustion of a premixed gas of methane/air in this new style reactor with...
With the background of the normal energy drying out, the utilization of low caloric value fuel is becoming more and more important. The Swiss-roll combustor is very applicable to low caloric value gas fuel. In order to make the combustor satisfied to combust the changing concentration low heat value gas fuel, the paper improves the conventional-scale Swiss-roll burner in which the SiC porous media,...
In order to study the characteristics of a new two-stage dry feed gasifier with multi underneath nozzles jetting tangentially, numerical simulation and analysis of the gasifier for high ash melting point pulverized coal was conducted based on Fluent. A comprehensive mathematical model for simulation of pulverized coal gasifier has been developed in this paper, chemical process was described with presumed...
Flameless combustion was first to developed suppress thermal NOx formation and raise the efficiency of combustion. Now in further research, three different combustion technologies can be used to achieve flameless combustion those are high temperature air combustion (HTAC), normal temperature air combustion (NTAC) and oxy-fuel flameless combustion. This paper presents a description of the three different...
