Design and analysis of plastic fin-tube heat exchanger for flue gas heat recovery
Heat loss due to exhausted flue gas accounts for more than half of boiler's total heat losses. Flue gas heat recovery helps to reduce both fuel consumption and pollution emission
which is of great significance. One of the main problems in flue gas heat recovery that restricts the flue gas outlet temperature is the low temperature acid corrosion to metal heat exchangers. In order to overcome this problem
an anti-corrosion fin-tube heat exchanger based on thermally conductive plastic was designed as a low temperature economized. Using the heat recovery operational condition in a 1000 MW thermal power plant
the parameters of heat transfer area and outline dimensions of the heat exchanger were calculated by a validated mathematical model. Then
the influences of plastic thermal conductivity and number of flow paths on the design parameters were analyzed. It is hoped that the results in this paper could give some reference to engineering applications.
