Clinker kiln modernization project

Considering the operational landscape of Kryvyi Rig Cement, including the increasing demand for cement and the burgeoning alternative fuel market in Ukraine, alongside the accessibility of financing options such as loans from external entities for construction-related ventures, Kryvyi Rig Cement stands poised to embark on an investment initiative to renovate its current clinker kiln.

The purpose of the mentioned project is to modernize the kiln for burning alternative fuels and increase its productivity to 4 000 t/day (15% increase) to the maximum possible given the current design of the existing kiln.

The strategy of introducing alternative fuel at Kryvyi Rig Cement is planned to be implemented in 3 stages:

• Stage 1 – AP: 2…5% replacement + Kiln capacity: 4 000 t/h, 4th quarter of 2024 – 4th quarter of 2025:

– Stage 1.1 – reaching 5%…10% replacement on the calciner:

– Stage 1.2 – increase kiln productivity to 4 000 t/day of clinker

• Stage 2 – achievement of 20%…30% substitution on the calciner, 2026-2027
• Stage 3 – achieving 50% or more substitution on the calciner, 2027-2029

Economic effect

The economic effect of project implementation arises as a result:

• Replace ~45% of coal with RDF fuel (energy cost: coal – 6.0 USD/GJ (calorific value ~6 000 kcal/kg); RDF fuel – 4.2 USD/GJ (calorific value ~4 500 kcal/kg).
• Due to the reduction of energy consumption for clinker firing from 3.4 to 3.2 GJ/t of clinker.
