Steel construction for heat exchanger tower of the Märker Group

As part of the modernization of the Märker Group’s cement plant in Harburg/Bavaria, an innovative new kiln system was installed to replace the 50-year-old kiln.

Zeman & Co GmbH was responsible for the production and assembly of the steel structure. The very tight space conditions and the work during the often very stormy weather at a height of up to 122 meters posed a particular challenge. The order was completed in just under a year and around 2,700 tons of steel were processed.

Modernization is explicitly not about increasing production capacity, but about securing the location and improving environmental and climate protection. The modern stove will require significantly less fuel energy than the old one and fuel-related CO2 emissions will be reduced by around a quarter. This reduces CO2 emissions by around 60,000 tons every year. This is roughly equivalent to the annual oil heating emissions of 15,000 private households.

The prerequisite for achieving a high level of energy efficiency is a significantly higher heat exchanger tower. This enables Märker Zement to use the best available technology.
