Converting 100 kW waste heat at 130-150°C into electricity

This project is funded by the Dutch Economic Affairs within the framework of the Small Business Research Programme (SBIR).

Based on the four stage traveling wave concept, a 100 kW_T thermoacoustic power (TAP) generator is under construction now.

For the TAP project Aster collaborate with Huisman Innovations B.V. (www.huisman-elektro.nl) and Innoforte (www.innoforte.nl). Recently the first phase of this project which include also identification of component supplier and launching customers in industry is finished.

This project is carried out in the framework of phase two of the Dutch SBIR program. The 100 kW TAP will be installed at a paper manufacturing plant in the Netherlands for converting part of the flue gas at 130-150°C from the paper drying process into electricity. Emphasis in this project is on production and cost aspects lowering the investment per kW_e to a level competitive to ORC’s. After successful completion of this pilot, commercialization and delivery of 100kW_T to 1 MW_T thermoacoustic power generators for industrial waste heat recovery and as add-on for CHP systems is planned to begin in 2012.
