Directing against problems existing in the process of putting pulverous precoat filter into operation
a concrete flushing scheme for hot-state flushing of the direct air-cooled unit has been put forward:(1)not only flushing the air-cooled condenser and corresponding pipelines
but also flushing the drain pipelines and exhaust steam facility at the steam turbine side;(2)flushing has to be carried out according to the mode of repeatedly switching over between fan and fan
as well as between tubebandle and tubebandle;(3)flushing of the exhaust steam facility etc.has to be also carried out.The concrete flushing principle and method for enhancing the quality of flushing have been also given.
