Application of Heat Pipe and Heat Exchanger to Waste Heat Recovery of Flue Gas

The author briefly introduces heat pipe technology and analyses the heat transfer mechanism. The heat pipe exchangers have a lotof unique advantages. Therefore,they have been widely used in the industry, especially in the recovery and utilization of the low and midtemperature waste heat resources . It should improve the high temperature heat pipe work so as to develop application of the heat pipe exchangerin the high temperature waste heat resources.
