temperature control in id fans in cement plant

Process Fans Used in Cement Industry FD Fans, ID Fans

Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along with some dust particles.

Clinkerization Cement Plant Optimization

Lower Cyclone Temperature is considered most important and stable temperature in preheater to control pre-calciner fuel rate. It is generally maintained manually or by PID loop in the range of ±10 0 C, in the range 850-900 0C to ensure calcination between 90% to 95 %. Burning Zone Temperature is monitored by radiation pyrometer. Maintaining

Improving Fan System Performance

Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing. Although they can sometimes be used interchange-ably with centrifugal fans, axial fans are commonly used in “clean air,” low-pressure, high-volume

Induced Draft (ID) Fan Lubrication System Design Review

The ID fan problems have arisen from the bearing lubrication system which provides oil recirculation to the induction motor bearings and fan main shaft bearings. Consequently these issues have caused half-load unit (225 MW) run-backs and full unit (450 MW) trips over the past decade. This project’s aim is to analyse the ID fan lubrication
