Newheat announces its first industrial waste heat recovery installation

On-site energy that was previously wasted

Tile manufacturing relies on two gas-fuelled processes: a continuously operating kiln and a dryer that operates during the week. Until now, the heat contained in the kiln flue gases was released into the atmosphere.

The system developed by Newheat recovers these flue gases from three separate streams from the kiln and feeds them back into the dryer. In addition, a 122 MWh (1,500 m³) thermal storage system stores the heat generated at the weekend, when the dryer is shut down, for use during the week.

This project fits perfectly with our decarbonisation roadmap. By recovering waste heat from the kiln to power the dryer, we are making use of an energy resource available on site and significantly reducing our reliance on natural gas.

A competitive alternative to natural gas

For wienerberger, the challenge is twofold: to reduce gas consumption and to improve the carbon footprint of its roof tiles, a criterion that is becoming increasingly important in the construction sector.

Designed, developed and delivered on a turnkey basis under an EPC contract, the installation offers wienerberger a viable alternative to natural gas, without having to deal with the complexities of the engineering work.

The results: a reduction of nearly 80% in the dryer’s gas consumption and 2,000 tonnes of CO₂ avoided per year.

This first project in waste heat recovery demonstrates Newheat’s ability to combine different technologies in order to provide industrial clients with low-carbon heat that is sustainably competitive with natural gas.
