DREAM Technology Case Study: Heat Pipe Solutions


Heat-pipe technology is fostering a new generation of low-energy, low-emissions kilns. Heat pipes transfer waste heat from from the cooling stage, to be re-used for the drier, supplied to the kiln’s combustion system as combustion air or as a heat source for factory heating. Heat pipe technology is money-saving, clean and with lower carbon emissions from burning less fossil fuel. Therefore, it reduces the overall carbon footprint of the factory. As a result, it generates profit, giving the end-users a competitive advantage, which allows them to increase their profit margins. It also puts the end-users in a stronger position in the industry and enables them to generate higher level of growth within the market.


  • Low impact on existing processes. It can be designed as a module to add to existing machines with minimal changes;
  • Clean air (not contamined) thanks to the way the heat pipe works;
  • Decrease of carbon footprint of the plant.

Applications outside the project

  • Need of heat exchange to balance and reduce the energy consumption in production plant;
  • Furnaces/kilns retrofitting;
  • Process air for driers.

Design for Resource and Energy efficiency in cerAMic kilns

The DREAM project (Design for Resource and Energy efficiency in cerAMic kilns) aims to design, develop and demonstrate a radically improved architecture for ceramic industrial kilns, characterised by optimised energy consumption, reduced emissions, and lower operating costs compared to currently available technological solutions.
