摘要
结合烟气自循环系统的特点和技术难点,分析了自循环系统的计算方法和计算逻辑,重点分析系统漏风率和原煤水分对系统的影响。漏风率增大易使系统氧含量超标,不利于系统安全生产。原煤含水量提高可降低烟气中的含氧量,有利于制粉系统安全运行。
The author analyzed the calculation methods and logic of circulation system in combination of the characteristics and technical difficulty of the fume circulation system, focusing on analysis of pulverizing system air leakage rate and the impact of water content in the raw coal on the system. In- creasing the air leakage rate will lead to exceedingly high level of oxygen content, and endangers to system operation. Increasing water content in raw coal can reduce oxygen content in the fume, and en- sure system powder system safety operation.
