摘要
为降低机组基建综合成本,提高机组运行经济性水平,某电厂330 MW循环流化床机组对风烟系统配置进行技术创新,在国内首次采用一次风机和二次风机单列布置方式。一、二次风机单列布置明显降低了造价、占地等综合成本,也对风烟系统的设计提出了一些新的要求。该电厂330 MW循环流化床机组半年运行表明,单列布置的一、二次风机不但运行稳定可靠,而且具有运行效率高、检修维护成本低的特点。
In order to reduce the comprehensive costs of capital construction and improve the economic level of unit operation, a technical innovation is carried out in the air-gas system for one 330-MW CFB unit in a certain power plant. The scheme of single primary air （PA） fan and single secondary air （SA） fan is adopted for the first time in China, which significantly reduces the construction costs and land occupation. However, some new requirements are put forward for the air-gas system design accordingly. The half-a-year operation shows that single PA fan and single SA fan can operate stably and reliably with high efficiency and low maintenance costs.
