The world consumption of the coal has been increased very sharply during past few years result from oil exhaustion, fluctuation in the price of oil and low price competitiveness of alternative energy. The International Energy Agency (IEA) has estimated that coal will be available for over 110 years, with coal reserves of close to 860 billion tons. The pulverized coal is blended coal powder that the particle diameter under 10μm. It has advantage of combustion efficiency and flame stabilization. The use of coal blends is becoming increasingly common in pulverized-coal power plants because it improves the economic performance of these plants by diversifying the fuel range. However, although blending can improve combustion behaviors and decrease gaseous pollutant emissions, it has difficulty of design and operating the pulverized coal combustor because despite the small particle size, combustion process of pulverized coal is exceedingly complex. Because of that the detail study on the combustion characteristic is important for increasing of efficiency. As a base investigation for numerical calculation of pulverized coal combustion, this study verified validity of models and compare the numerical calculation results with the experimental results.
