How to Use This Calculator
- Enter production data: clinker production rate (TPD) and kiln feed rate (TPH)
- Enter fuel data: coal rate, NCV, alternative fuel substitution %, and preheater configuration
- Enter process data: exit gas temperature, ID fan flow, cooler vent, fan power
- Click Calculate: to see thermal efficiency, specific heat consumption, exit gas loss, false air estimate, specific power, and kiln loading
