Thermoelectric conversion of waste heat to power and process heat
report
In order to maintain the competitive position of the process industry in Europe, highest energy efficiency, lowest CO2 emissions and high economic efficiency of the production processes are a must. Consequently, the process industry is constantly looking to improve in these fields under the boundary conditions that the investments are cost efficient with a pay-back time of less than 3 years whilst having minimum impact on the production process itself. Waste heat recovery is considered a crucial opportunity with respect to energy efficiency improvement. Production processes in industries like the steel, glass, aluminum and ceramics, as well as waste incineration, involve high temperature processing and thereforeinevitably large amounts of high-temperature waste heat. Recovering part of the energy stored in waste heat will significantly lower production costs andCO2 emissions. In the high temperature range > 400°C, the options for feasible technologies have been quite restrictive so far. In this temperature domain, thermoelectric generation will add a new option and disclose a potential for waste heat recovery that has not been available thus far.
