Abstract

EN The article presents the construction of modular a shell and tube heat exchanger, which is proposed for food industry. Authors analyzed possibilities of applying this type of heat exchanger to recover waste heat from a heating boiler used in food production companies. Recovered waste heat can be utilized for palm oil heating, which is a common ingredient used in food companies. This construction of heat exchanger allows controlling a heating power of realized process by simple adjusting area of heat transfer by a system of valves, by disconnecting subsequent sections of the heat exchanger from the plant, when heat requirement is decreasing. The research was divided into two parts. First analytical calculations, related to the design of the heat exchanger were realized. Subsequently, the power of heat exchanger obtained during analytical calculations was compared to numerical calculations. The numerical analysis allowed to demonstrate that the flow of exhaust gases through the shell side of the heat exchanger is not homogenous. Prepared numerical calculations showed the non-uniform character of flow through the subsequent modules of the heat exchanger.
