Hot-blast F.D.-fans and I.D.-fans of Gas Recirculation
Hot-blast FD fans and ID fans of gas recirculation are employed in systems where fuel is dried and prepared for combustion, in flue gas recirculation systems of boiler units as well as in operation lines of metallurgical and other works. Maximum temperature of handled medium at the inlet of hot-blast FD fans and ID fans of gas recirculation must not exceed 400 °C. At the same time there are several exclusions concerning temperature of handled medium at fan inlet. Maximum temperature for ВГД-22SД is 250 ◦C, while for ДРГ-19.5 and for ДРГ-19.5Ф it comes to 420 °C.
