Summary
The Saint-Martin-Lalande plant is Newheat’s first industrial waste heat recovery project delivered under an EPC (Engineering, Procurement & Construction) contract. Deployed at wienerberger’s tile production site in the Aude region, it captures heat from the kiln’s flue gases, previously released into the atmosphere, and redirects it into the dryer to replace natural gas. A 122 MWh thermal storage system stores the heat produced over the weekend to supply the dryer during the week, maximising the site’s energy recovery.
This project fits perfectly into our decarbonisation roadmap. By recovering waste heat from the kiln to supply the dryer, we are making use of an energy resource already available on site and significantly reducing our reliance on natural gas
Presentation of the heat consumer client
- wienerberger, manufacturer of terracotta construction materials, Saint-Martin-Lalande site (Aude)
- Plant using natural gas for two thermal processes : drying and firing of roof tiles
Principle of technology integration
- Heat recovery from three flows from the firing kiln :
- Kiln flue gases
- Under-car air
- HT/LT recovery air at weekends
- Heat valorised in the dryer as a replacement for natural gas
- 122 MWh thermal storage (1,500 m³ tank) retaining weekend heat production to supply the dryer during the week
- Fossil fuel displaced : Natural gas
Key innovation(s)
- Newheat’s first industrial waste heat recovery reference and delivered under an EPC contract
- Simultaneous multi-source recovery on firing kiln
- Thermal storage sized to bridge the production/consumption gap between weekends and working week
