<p>Combustion phenomena and model experiment in tuyere and raceway region in blast furnace were reviewed. In blast furnace, coke charged from furnace top and pulverized coal injected from tuyeres are main energy source, they are burned by blast blown from tuyeres. Combustion behavior in blast furnace raceway have the characteristic of high temperature blast, high temperature coke combustion, loose coke packed bed combustion, competitive reaction of coke and coal, mainly CO gas generation, so it is much different from another purverized coal combustion process such as a boiler for coal-fired power plant. Model experiment on raceway generation and combustion has been studied since long before. From the past coke-main operation period to recent high pulverized coal ratio operation period, research on combustion in tuyere and raceway region were explained.</p>
