Example of a real project
Initial situation:
Long rotary kiln with a high thermal energy consumption, a O2 content at ESP outlet of 8 ÷ 10%, very frequent CO peaks

Audit findings:
Uncontrolled entries of false air and dilution air at different locations
Erratic solid fuel dosing
No regulation between secondary air fan and fan at stack

First picture of example
Improvements:
Removal of false air entries
Installation of a quenching system in front of the ESP
Change of solid fuel dosing
Regulation between secondary air fan and exhaust fan

Results:
Thermal energy consumption ↓
Electrical energy consumption ↓
