+7 (4942) 622-023Smoke exhauster centrifugal single-sided ГД, ДРГ and double-sided (ГД-x2 and ДРГ-x2) suction is used to remove flue gases from solid fuel boilers in large industry (steel foundries, boilers and dryers). They move a large volume of air (temperature up to 400 ° C) and are relatively economical in electricity consumption, therefore it is preferred in the choice for many enterprises.
Exhauster hot exhaust and recirculation fans are designed for drying and fuel preparation, in flue gas recirculation systems in boiler units, in technological lines of metallurgical and other industries. There is no fundamental difference in them. Their impellers are made of heat-resistant steel. There is a system for cooling the chassis shaft. The maximum temperature of the medium at the inlet to the hot blast fans and the recirculation chimney must not exceed + 400 ° C. The exceptions are: ВГД-22SDRK – tmax = 250 ° C; ДРГ-19.5K, ДРГ-19.5FK – tmax = 420 ° C.
