An investigation of how electron/photon beam exposures affect the intercalation rate of Na deposited on graphene prepared on Si-face SiC is presented. Focused radiation from a storage ring is used for soft X-ray exposures while the electron beam in a low energy electron microscope is utilized for electron exposures. The microscopy and core level spectroscopy data presented clearly show that the...

Optimal inspection and maintenance of complex systems in modern industry is important for safety and economic reasons. With appropriate statistical modelling, the utilisation of inspection resources and quality of inferences can be greatly improved. Modelling and inspection of a full-scale industrial furnace subject to corrosion is considered. A suitable Bayesian spatio-temporal dynamic linear ...

In this work, the effects of scale on thermal behavior of the slab in a walking-beam type reheating furnace is studied by considering scale formation and growth in a furnace environment. Also, mathematical heat transfer model to predict the thermal radiation in a complex shaped reheating furnace with slab and skid buttons is developed with combined nongray WSGGM and blocked-off solution procedu...

Ethylene cracking furnace system is the heart of ethylene production. It can process different raw materials in the pipe group of each furnace and can produce the main chemical products like ethylene, propylene and ethane. In the real world ethylene plant, there are two operation modes in the furnace system, one has a backup furnace in the system and the other is with all the furnaces available...

Abstract Producing high-silicon alloys in submerged arc furnaces (SAF) involves the generation of an intermediate process gas, consisting silicon monoxide (SiO) and carbon (CO). Combustion gas from taphole can be environmental challenge. SiO burns to fine 2 particles which cause poor working conditions fugitive particulate matter emissions. The high combustion energy CO is a source heat load. I...

In this present work, simulations of 20 kW furnace were carried out with hydrogen-enriched methane mixtures, to identify optimal geometrical configurations and operating conditions operate in flameless combustion regime. The objective work is show the advantages for fuels limits current typical industrial designs these mixtures. performances a semi-industrial chamber equipped self-recuperative ...
