Single suction centrifugal smoke exhausters type DN
- Guide apparatus;
- Suction funnel;
- Spiral housing;
- Working wheel;
- Chassis.
Centrifugal smoke exhausters of one-sided suction type DN are designed for suction of flue gases from the furnaces of stationary steam boilers with a steam capacity of up to 320 t/h with a residual dust content of flue gases of not more than 2 g/m3. It is allowed to use smoke exhausters in technological installations for moving non-aggressive gases with a dust content of solid particles of not more than 2 g/m3, which do not differ from flue gas ash in terms of abrasiveness and tendency to sticking. The maximum allowable temperature of transported flue gases at the inlet to smoke exhausters should not exceed +250 °C. Type of impeller blades - sheet, backward curved. The index "GM" is added to the designation of smoke exhausters for gas-oil boilers. Smoke exhausters are issued the left and right direction of rotation.

Centrifugal smoke exhausters of double suction type DNx2 are designed for suction of flue gases from the furnaces of stationary steam boilers with a steam capacity of up to 480 t/h with a residual dust content of flue gases of not more than 2 g/m3. It is allowed to use smoke exhausters in technological installations for moving non-aggressive gases with a dust content of solid particles of not more than 2 g/m3, which do not differ from flue gas ash in terms of abrasiveness and tendency to sticking. The maximum allowable temperature of transported flue gases at the inlet to smoke exhausters must not exceed +250°C. The type of impeller blades is sheet, backward-curved, with the exception of the DN-31x2GM smoke exhauster, which has profiled hollow blades. The index "GM" is added to the designation of smoke exhausters for gas-oil boilers. The same type of smoke exhausters designed for solid or gaseous (liquid) fuel boilers have the same aerodynamic characteristics. Smoke exhausters are issued the left and right direction of rotation.
High-pressure centrifugal smoke exhausters of one-way and two-way suction type D and Dx2 are designed for suction of flue gases from the furnaces of stationary steam boilers with a steam capacity of up to 640 t/h and use in process plants for moving non-aggressive gases with a dust content of solid particles of not more than 2 g/m3, in terms of abrasiveness not different from flue gas ash. The maximum allowable temperature of transported flue gases at the inlet to smoke exhausters should not exceed +250 °C. Type of impeller blades - sheet, forward curved. In terms of installation and connecting dimensions, smoke exhausters D and Dx2 correspond to previously produced models of the same smoke exhausters.
Smoke exhausters are issued the left and right direction of rotation.
