Abstract: The heat exchanger is the most important auxiliary engine equipment system in cogeneration units. Introduction was made to the structural features of all-welded plate heat exchangers, the heat diffusion principle and its application in cogeneration units. This paper compared and analyzed it with traditional shell-and-tube heat exchanger. The analysis results show that the all-welded plate heat exchanger has advantages of both new type removable heat exchanger and traditional shell-and-tube heat exchanger, possesses distinguished heat transfer property under the heat diffusion working conditions of high temperature and high pressure medium, and can replace the shell-and-tube heat exchanger sufficiently under multiple working conditions.
Key words: all-welded plate heat exchanger; cogeneration units; shell-and-tube heat exchanger
