NUMERICAL SIMULATION OF COAL COMBUSTION IN ANGENTIAL FIRED BOILER FURNACE── CONSTANT DENSITY MODEL OR CONSTANT DIAMETER MODEL FOR THE COAL PARTICLE
-
摘要: 用等密度模型和等直径模型模拟了切圆燃烧锅炉内的燃烧过程。用计算粒子来描述煤粉粒子群的运动和燃烧。假定粒子群围绕计算粒子呈正态分布来求得炉内燃烧热的分布。Abstract: The pulverized coal combustion process is simulated numerically in a tangentially fired furnace with either a constant density model or a constant diameter model of the coal particle. The motion and combustion of pulverized coal is described with the concept of the computational particle,The distribution of heat release from combustion is obtained by statistics based on the assumption of normal distribution of pulverized coal mass around the computational particle.
