摘要
分析了循环流化床锅炉中燃烧过程及给煤的混合过程,探讨了系统简化性能可靠的前墙给煤的可行性,研究了这一变化对燃烧效率的影响。认为前墙给煤可靠性提高,便于操作,对燃烧效率的影响较小。而燃烧效率主要取决于原煤的反应活性以及混合效果。
The combustion processes of coal particle and its mixture in bed material is analyzed. The feasibility of coal feeding in front wall in stead of return pipe of loopseal and its effect on the combustion efficiency are also discussed. The reliability of coal feeding in front wall is higher while the coal feeding system is simple to operation, which is almost no effect on combustion efficiency, which mainly depends on original coal characteristic and the mixing of solids and gas.
