目前,我国能源总消耗70%以上是煤,在火力发电中基本上以煤为燃料。随着锅炉容量和参数的发展,煤粉炉在电站中得到了最广泛的应用。我国大型电站锅炉迅速发展,其可靠性和经济性都达到了较好的水平。按不同煤种分析现有各类锅炉的运行状况可见,切圆燃烧锅炉炉膛出口烟气能量不平衡问题已基本解决,NO_x的排放浓度问题正逐步治理和解决,但一些锅炉存在炉内结渣等问题严重影响锅炉运行的安全性、经济性和可靠性。1煤粉炉的炉膛及燃烧器
At present, China’s total energy consumption is more than 70% coal, coal-fired power is basically in the thermal power. With the development of boiler capacity and parameters, pulverized coal furnace has been the most widely used in power plants. The rapid development of large-scale power station boilers in China, the reliability and economy have reached a better level. According to different types of coal analysis of the existing operating conditions of various types of boilers can be seen, tangentially fired furnace outlet flue gas energy imbalance problem has been basically solved, NO_x emissions concentration problems are gradually addressed and resolved, but some boilers have slag And other issues seriously affect the safety of boiler operation, economy and reliability. 1 pulverized coal furnace hearth and burner
