, and the influence of CO in sintering process was investigated. The results show that the post-combustion of CO conducts in sinter zone when flue gas passes through the sintering bed, which releases much...Combustion behavior and influence mechanism of CO on iron ore sintering with flue gas recirculationFAN Xiao-hui(范晓慧), YU Zhi-yuan(余志元), GAN Min(甘敏), CHEN Xu-ling(陈许玲), JI Zhi-yun(季志云) (School......
by the finite volume method on the basis of the gas-solid reaction The numerical analysis shows that the equilibrium constant is an important factor influencing the process of gas-solid reaction... obviously when the stoichiometric coefficients satisfy a/c≠1. Key words: porous media; compressible gas flow; reversible chemical reaction; interaction 1 Introduction The process of gas flowing through......
welding. The preferred welding process of titanium alloy is frequently gas tungsten arc(GTA) welding due to its comparatively easier applicability and better economy. In the case of single pass GTA... thermal gradients in welds in relation to castings and the epitaxial nature of the growth process[2]. Pulsed current gas tungsten arc(PCGTA) welding, is a variation of GTA welding, which involves......
Effect of carrier gas pressure on vapor condensation and mass flow-rate in sonic nozzleDING Hong-bing(丁红兵), WANG Chao(王超), CHEN Chao(陈超) (Tianjin Key Laboratory of Process Measurement and Control... process is not easy to occur at lower carrier pressure and throat diameter. The main factors influencing condensation onset are boundary layer thickness, heat capacity of carrier gas and expansion rate. All......
