根据国家能源政策， 燃用优质燃料的高压煤粉炉被要求停机以改善环境。循环流化床燃烧技术逐渐成熟， 为煤粉炉改造为燃用劣质燃料同时满足日益严格的环保要求的改造提高技术。在详细计算和研究的基础上提出了２２０ｔ／ｈ 煤粉炉改造为循环流化床锅炉的方案。该方案充分利用原有条件， 设计合理， 性能可靠。
According to the national energy policy, high-pressure pulverized coal fired with high-quality fuel is required to shut down to improve the environment. Circulating fluidized bed combustion technology is gradually maturing, for the transformation of pulverized coal fired boilers to use inferior fuel while meeting the increasingly stringent environmental requirements of the transformation and upgrading of technology. On the basis of detailed calculation and research, the scheme of retrofitting a 220 t / h pulverized coal fired boiler into a circulating fluidized bed boiler is proposed. The program make full use of the original conditions, reasonable design, reliable performance.
