Studies and Calculations on Theory of Coal Char in High-pressure O_2/CO_2 Atmosphere

研究表明在6MPa压力,富氧浓度为30%的条件下的增压富氧燃烧的经济性可以达到最佳。在此气氛下用一个简单的燃烧模型对碳球燃烧的情况进行理论计算,与空气气氛下的燃烧情况作对比,得到增压富氧燃烧在煤粉的燃烧时间和对烟气捕集回收二氧化碳上的优越性。从而为增压富氧燃烧的进一步发展提供理论基础。

Studies have shown that in 6MPa pressure and 30% of the oxygen concentration conditions, pressurized oxygen enriched combustion economy can achieve the best. In this atmosphere, the combustion condition of carbon ball was calculated using a simple combustion model. Compared with air atmosphere combustion, get the superiority of high-pressure oxygen - enriched combustion in pulverized coal combustion time and the smoke trapping carbon dioxide. Pressurized oxygen -enriched combustion provide a theoretical basis for the further development.
