To develop an innovative cogeneration biomass boiler, which uses thermoelectric generators (TEG), a simplified model of the heat exchanger is created and the design is optimized. The boiler with a thermal power of 200 kW will partly convert the heat into electricity. The maximum temperature of the hot side of the TEG should not exceed 300°C to avoid damage. While holding these requirements the cost and the installation space of the heat exchanger should be as low as possible, with a minimal effort for the flue gas blowers at once. Following these objectives, the simplified heat exchanger model is optimized with NOMAD optimization algorithm. Out of the resulting Pareto front two heat exchanger designs are discussed.
