Abstract: Properly understanding heat flux characteristics is a crucial prerequisite to efficiently applying a regenerative burner in an aluminum reheating furnace. A series of experiments was conducted in this study in order to establish a database of the best available burners according to furnace temperature, excess air ratio, and flame combustion mode as they affect heat flux characteristic...

Abstract Most refinery and petrochemical reaction furnaces are operated under harsh conditions characterized by high pressures, temperature, aggressiveness of the process environment. The temperature features heated raw material contribute to formation deposition coke on surface furnace pipes, which through adhesion diffusion phenomena has a negative effect reduces operational reliability entir...

This paper presents a numerical model for the prediction of minimum ignition temperature (MIT) dust clouds. First, physical is developed cloud in Godbert-Greenwald furnace. A approach then applied MIT based on model. The considers heat transfer between air and particles, particle reaction kinetics, residence times clouds In general, 13 dusts studied, calculated data are agreement with experimen...

In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...

laboratory and industrial scale experiments are made on the application of sponge iron pellets and briquettes for the production of cast iron and steel in different melting systems, such as electric induction furnace, electric resistance furnace and fuel-fired crucible furnace. effect of various variables such as specifications of sponge iron, temperature of the molten metal and the method of f...

Thermal water splitting by redox reactants could contribute to a hydrogen-based energy economy. The authors previously assessed and classified these thermo-chemical reactions. Mn3O4/MnO/NaMnO2 multi-step cycles were demonstrated have high potential. present research experimentally investigated the MnOx/Na2CO3 system both in an electric furnace concentrated solar at 775 825 °C, respectively, usi...

Thegoal. Silicon carbide is one of the most essential artificial inorganic materials widely used to produce abrasive instruments, high-temperature heaters, fireclay ceramics, and metallurgy. The amount silicon produces in resistance furnaces. One issues production process lack supervisory thermal state furnace working space, which does not always allow for select rational electrical modes accor...

The reduction of V2O5 and WO3 with hydrogen, the latter which is performed industrially in rotary kilns under a hydrogen countercurrent, has been investigated by using situ X-ray powder diffraction. This method yields insights into processes illustrated transparent section furnace, thus gaining information about reaction pathways as well compositions structures intermediates. More can be found ...
