The Chimney Heat Potential to be Converted into Electrical Energy with Thermoelectric Generator: Dimensionless Analysis

The gas-steam power plant combines a gas and steam plant, where Heat Recovery Steam Generator (HRSG) is unit for generating steam. waste heat from this system channelled to the chimney with Thermoelectric (TEG) module generate electrical energy. TEG uses thermal conduction process wall, height, diameter, velocity variables are considered analysis. To optimize analysis, we used dimensional analysis get laboratory-scale system, method matrix dimensionless of balance energy equation. As result investigation, calculation potential obtained; condition temperature will increase when increases value diameter height decrease, then there have an error about 14% design chimney.
