Maerz Ofenbau AG realises new lime kiln for Leube Zement GmbH, Austria

Turnkey high-tech plant with a focus on sustainability and efficiency

At the heart of the new plant is the lime kiln of the latest Maerz C series. The innovative suspended cylinder technology – combined with highly efficient high-pressure fans – ensures an even heat distribution and thus significantly reduced energy consumption. Due to the optimised gas flow in the suspended cylinders, calcination is precise and efficient, while the high-pressure fans reduce power consumption to a minimum. This technical solution sets a new standard for modern lime production.

The plant replaces an existing multi-chamber shaft kiln from 1989, with the new technology representing a significant advance in kiln technology.

Renewable energies and flexible fuel use

The lime kiln is primarily powered by biomass – a central pillar of Leube's sustainability strategy. At the same time, the plant enables flexible operation with natural gas or mixed operation, which ensures operational reliability and adaptability. The integrated collection of CO₂ in the low-pressure storage system allows the efficient use of carbon dioxide. The plant makes a significant contribution to the reduction of CO₂ emissions.

A contribution to the climate-friendly building materials industry

With this project, Maerz Ofenbau AG is supporting its customer's ambitious environmental goals. The plant impressively demonstrates how innovative kiln technology promotes sustainable transformations and social responsibility in the building materials industry – through efficiency and innovation.
