By purpose the centrifugal forced-draft machines are divided into forced-draft fans, basic induced-draft fans, mill fans, recirculation induced-draft fans and hot blowing fans; fans and special purposes induced-draft fans.
VDN, VD forced-draft fans are designed to transfer clean air at a temperature up to 100°C.
Basic induced-draft fans of DN type DNx2 D and Dx2 are designed to transfer flue gases at temperatures up to 250 ° along the gas paths in boilers and gas cleaning systems. The permitted loading of the transferred gases with ash , and dust with similar abrasive characteristics is 2 g/nm3
Mill fans of VM VVN type. VVR. VVSM are used to transfer the dust-loaded air in the systems of preparation and supply of coal dust to boiler furnaces. The ultimate temperature of the air mixture is 150°C. The permissible dust loading of the air with particles of coal, or other dust similar to it in terms of abrasive characteristics, is 80 g/Nm3.
The regular fans and induced-draft fans of special purpose (including corrosion-resistant ones) are intended for use in processing lines at the industrial plants at temperatures up to 450°C (with availability of a system for additional air cooling of the running gear).ORDER EQUIPMENT
