 Title: 200MW steam turbine technology in the rapid cooling of air power company's application Hunjiang
ABSTRACT
 This paper Hunjiang 200MW steam turbine power generation company as an example discusses the use of omni-directional air cylinder of the reasons for the rapid cooling, layout, operation, adjustment, but also from the security and economy on the use of double air cylinder significance of rapid cooling. For 200MW steam turbine cooling down the cylinder needs to be accelerated after the issue of an effective, efficient cooling of the rapid cooling cylinder steam turbine technology, so as to shorten the repair period and to enhance the utilization of generating units, has obvious relevance and economic significance.
