600 MW机组省煤器灰中等距离气力输送系统改进措施

摘要

The problem of plu9 flow and convey time-out often appears in pneumatic conveyin9 of ash in coal e-conomizer in one 2 x 600 MW units durin9 startup time. When replaced with dual-tube-socket,chan9ed con-veyin9 sequence and reduced air capacity,the operation of conveyin9 system is stable.%某电厂省煤器灰气力输送系统投运初期频繁出现堵管和输灰超时的问题。经过分析及调研后，改用双套管输送，优化输送步序，减少输送耗气量，不仅实现了输送系统平稳顺畅，而且避免了灰管过度磨损的现象。
