, Ltd, the scaling causes are analyzed on the flashing cooler of extraction and the reflux line for phosphoric acid production from dihydrated phosphogypsum process.

The programming research of simplified thermal calculation for plate indirect evaporative cooler;

Several mathematical models of tube type indirect evaporative coolers are introduced and compared.

To improve the hydrophilic of tube type indirect evaporative cooler wall surface,the use of porous ceramics material is put forward,combinated of porous ceramics and evaporative cooling technique,and the design calculation of porous ceramics tube type dew point indirect evaporative cooler is carried out from aspects of air volume,air status parameter,structure,heat-transfer and resistance.
