Clinker kiln modernization project

About the Project

Kryvyi Rig Cement is initiating an investment project to renovate its current clinker kiln, aiming to modernize it for burning alternative fuels and increase productivity to 4,000 t/day (a 15% increase), maximizing the potential of the existing kiln design.

Project Strategy and Timeline

The introduction of alternative fuel will be implemented in three stages:

• Stage 1 (4th quarter 2024 – 4th quarter 2025):
  • Alternative fuel replacement: 2–5%
  • Kiln capacity: 4,000 t/day
  • Stage 1.1: Reach 5–10% replacement on the calciner
  • Stage 1.2: Increase kiln productivity to 4,000 t/day of clinker
• Stage 2 (2026–2027): Achieve 20–30% substitution on the calciner
• Stage 3 (2027–2029): Achieve 50% or more substitution on the calciner

Economic Effect

• Replace approximately 45% of coal with RDF (Refuse-Derived Fuel), reducing energy costs:
  • Coal: 6.0 USD/GJ (calorific value ~6,000 kcal/kg)
  • RDF fuel: 4.2 USD/GJ (calorific value ~4,500 kcal/kg)
• Reduce energy consumption for clinker firing from 3.4 to 3.2 GJ per ton of clinker
