Comparison a simulation model of heat exchanger with real equipment

Proposed article deals with simulation model of heat exchanger and its comparison with real equipment. Heat exchanger is an equipment which is used for heating-up one medium by the other. Indirect heat transfer is considered i.e. medium are not in direct contact and heat transfer occurs through the wall. Mentioned heat exchanger is typical for area of raw materials processing and it is used mainly for preheating of combustion air, fuel. Exchanger is also used for cooling of equipment, warmed products etc. In the case of exchanger, above all, processes of heat transfer by convection, heat transfer by conduction and accumulation of heat are modelled and described in article. Mathematical model built by means of balancing equations represents base of simulation model created in Matlab Simulink by using s-function. Real data is gained from laboratory experimental equipment and are compared with simulation results. In the end part of article reasons of variation of data from simulation model and from real equipment are analyzed. Possibilities of improving and extension of model to create model more exactly are mentioned.
