/煤粉炉改造为循环流化床锅炉的方案设计 /

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。 The pulverized coalfired boiler burned high grade coal will be shut down according to the national energy policy because of its high emissions. It is possible to retrofit PC boiler into circulating fluidized bed boiler where low grade coal can be used as the fuel. Based on detail calculation, a concept design was introduced in this paper. The original condition was considered in this reasonable design, its performance is insured
