Heat exchanger design to improve the efficiency of industrial plant

In thesis is done thermal-hydraulic design of cross-flow tubular heat exchanger for combustion air preheating. In software Chemcad is done simulation of technological unit based on known operating data, which is used for behavior prediction of unit after heat exchanger installation. Then there are discussed essential mechanisms of heat transfer. After that there is overview of different heat exchanger types used for combustion air preheating. Before particular design there is performed optimalization of heat duty of heat exchnger based on payback time. Thermal-hydraulic design is performed using F-LMTD method in software GNU Octave. Obtained results are verified using software HTRI Xchanger Suite®. At the end there are discussed economical and ecological benefits of designed heat exchanger
