In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near t...

The volatilization of zinc in the electric arc furnace dust–CaCl2 and ZnFe2O4–ZnO–CaCl2–C reaction systems was investigated. Experiments were conducted under an N2 atmosphere infrared lamp heating furnace, activation energy rate determined by Ozawa method. system 123 ± 27 kJ/mol; when dust decarburized, reduced to 84 4 kJ/mol. Further, simultaneous carbothermic reduction carbon contained chlori...

The work presented in this thesis focuses on reducing the energy demand of a residential building by using a coupled ground-source heat pump/energy recovery ventilation (GSHP-ERV) system to present a novel approach to space condition and domestic hot water supply for a residence. The proposed system is capable of providing hot water on-demand with a high coefficient of performance (COP), thus e...

Introduction: We carried out evaporation experiments on Fe-FeS melt and obtained evaporation rates of sulfur from Fe-FeS melt. The Fe-FeS eutectic temperature is about 988°C (1261K), and this temperature could be achieved in the inner region of the solar nebula, and it should be also achieved during the chondrule formation. It is of importance to understand evaporation kinetics of Fe-FeS melt f...

The physical properties desired for various applications of aluminum alloys are usually modified by tailoring their precipitation behavior during heat treatment. In this study, the a cast Al–Mn alloy annealed with two heating methods (electric resistance and radiative furnace heating) at different temperature has been studied through electrical conductivity (EC) test, scanning electron microsco...

The aim of this study is to fabricate in-situ TiC particle reinforced Fe matrix composites via volume combustion synthesis (VCS) through heating by two different sources. One group reactant pellets was ignited in an induction furnace (IF). other using a tungsten inert gas (TIG) torch. Thus, the differences microhardness and microstructure obtained could be compared. Fe, C Ti elemental powders w...

For the sintering of ceramic products, high-temperature electric furnaces are used, which work both in a protective environment and air. In some technological processes, for example, production carriers afterburning car exhaust gases based on SiC Al2O3, only air used. Silicon carbide (SiC – silicate) heaters molybdenum disilicide (MoSi2) used as resistive such furnaces. Due to relatively small ...
