摘要
驱动马达为小汽轮机的引风机与常规电动机驱动的引风机相比,其启动和并联具有特殊性。通过分析探讨可知,在引风机进口加补气门可保证单台引风机安全启动,在引风机进出口加烟气循环联络烟道可保证两台风机安全并联运行。
The start and operation in parallel of indraft fan driven by turbine is particular, which is different from fan driven by electric motor. An air-supplying gate is set in the inlet of indraft fan can ensure the safe start of a single set of fan. And a measure is introduced to assure the stable run in parallel of two sets of fans by means of adding a gas-circuiting conduit between the two fans.
