In our laboratory, we are working on energy and environmental issues with combustion and heat transfer engineering as basic technologies, and conducting research that will lead to reduction of CO2 emissions as a measure to prevent global warming. Research themes include (1) research on blown fuel conversion (from coal to natural gas and biomass) in iron-making blast furnaces, (2) research on heat transfer behavior of threads with non-uniform thermal conductivity, and (3) energy sources, consumption, and emissions in industry. We will carry out research on flow efficiency. Students will acquire "Practical learning" research methods, experimental techniques, analysis, and report writing skills that will be linked to the industrial process of manufacturing based on the knowledge of mathematics, physics, chemistry, thermodynamics, combustion engineering, etc. that students have learned in the undergraduate school. ..

Research on fuel conversion and efficiency improvement in combustion and heat transfer processes -Toward the construction of a low-carbon society-
Research on in-furnace behavior to reduce CO2 emissions from iron-making blast furnaces In iron-making blast furnaces, coal and coke are used as a source of reduction of iron ore and heat energy, so a large amount of CO2 is generated. When changing the fuel from a fuel with a high carbon ratio such as coal to a fuel with a high hydrogen ratio such as natural gas and biomass in order to reduce CO2 emissions, we will investigate how the combustion and flow behavior change due to changes in the fuel type. We will conduct cold model experiments mainly assuming a blast furnace, analyze and consider the results, and predict the actual furnace phenomenon.
Study on temperature rise and melting behavior of solid by heat transfer from high temperature gas In an iron-making blast furnace, low-temperature solid particles (iron ore) charged from the top of the furnace heat up and melt due to heat transfer from the high-temperature gas that rises from below. The efficiency of this heat transfer greatly affects productivity and energy intensity. We are investigating the mechanism and controlling factors of heat transfer from high-temperature gas to solids in the furnace and temperature rise / melting by conducting model experiments and computer simulations. In the future, we will not use fossil fuels instead of blast furnaces (CO 2 It can also be applied to the process of iron making in a (carbon-neutral) hydrogen reduction furnace that does not emit.
