在数十台75t/h和130t/循环流化床成功运行的基础上, 开发了220t/h采用水冷方形分离器的循环流化床锅炉,2001年底在山东威海热电厂投入商业运行。这是采用中国技术的容量最大的循环流化床锅炉之一。文中介绍了该炉的运行情况。由于水冷方形分离器本身的特点以及全膜式壁结构,锅炉迅速启动以及回灰温度略微下降等特性非常突出。飞灰、循环灰和底渣的粒度分布与燃用相似煤种等当量直径圆旋风筒循环流化床锅炉非常相似。燃烧效率比较理想,污染物排放满足国家标准要求。其燃料适应性、负荷变化率尤其是可靠性非常优越。
Based on the successful operation of dozens of 75t / h and 130t / circulating fluidized beds, a 220t / h circulating fluidized bed boiler with water-cooled square separator was developed. Commercial operation was carried out in Shandong Weihai Thermal Power Plant by the end of 2001. This is one of the largest circulating fluidized bed boilers using Chinese technology. The article describes the operation of the furnace. Due to the characteristics of the water-cooled square separator itself and the full-film wall construction, the quick start-up of the boiler and the slight drop in ash return temperature are all outstanding features. The particle size distribution of fly ash, recycled ash and bottom slag is very similar to that of a similar coal equivalent circular toroidal-tube circulating fluidized bed boiler. Better combustion efficiency, pollutant emissions to meet the national standards. Its fuel adaptability, load change rate, especially the reliability is very superior.
