ABSTRACT

This article summary presents the use, features, basic operating principle of rotary - thermal

recovery air heater - important equipment unit in coal-thermal power plants with a capacity of 300 to

600 MW. The ability to fall the wind in this heater have great significance not only for the heater's performance,

but also an important influence on the performance of the whole plant Calculated content of ability for

the failed wind and the optimal structural design, material are also studied in this article. The research

results have been applied well in actual at Hai Phong coal-thermal power plant.

Keywords: Calculation, design; Rotary - thermal recovery air heater; Failed wind.
