Mechanically Activated Self-propagating High temperature Synthesis (MASHS) is the method which is used to promote self-propagating synthesis by increasing activity of reactants and increase the purity of products. In this study Ti 2 AlC and Ti3AlC2 max phases were synthesized by using mechanically activated self-propagating high temperature synthesis (MASHS) and samples reactivity and phase str...

Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required ...

This study aimed at comparing various advanced oxidation processes (H2O2, UV, UV/H2O2, Fe /H2O2, UV/Fe /H2O2) for textile dye Reactive Red 195 decolorization. The use of blast furnace dust (BFD) was also investigated as an alternative source of iron in catalytic peroxidation with and without UV radiation. The effects of H2O2 and dye concentrations in kinetics of decolorization were studied. Dec...

We report the growth of ultralong (>10 cm) multi-walled and single-walled carbon nanotubes such that the length is limited by the size of the furnace rather than by the termination of growth. The disturbance of microscale laminar flows results in disordered or shorter growth of carbon nanotubes. By downsizing reaction pipes, reaction gas flows are stabilized with low Reynolds numbers. In this w...

A mathematical heat transfer model for the prediction of transient heating of the slab in a direct-fired walking beam type reheating furnace has been developed by considering the nongray thermal radiation with given furnace environments. The furnace is modeled as radiating nongray medium with carbon dioxide and water with five-zoned gas temperature and the furnace wall is considered as a consta...

An analytical model of a spreader-stoker wood waste fired boiler has been developed for pre­ dicting the size of the largest particle which can be entrained by the upward motion of the furnace gases. This model is based on an entrainment model which equates particle in-situ settling velocity to furnace gas velocity and uses a stirred reactor mod­ el to evaluate furnace conditions. The effects o...
