The start-up characteristics, quasi-steady operation characteristics, and the temperature variation regular of pulsating heat pipe heat exchanger when working fluid containing non condensable steam in steam were studied and experimented on. The pulsating heat pipe heat exchanger were designed and calculated using flue gas as the working fluid. Pulsating heat pipe heat exchangers with flue gas as working fluid were design and calculation, based on the calculation of traditional gravity heat pipe heat exchangers and combined with the characteristics of pulsating heat pipes themselves. Experimental data by analysis, it is found that under experimental conditions, the pulsating heat pipe heat exchanger has a fast response and good start-up performance. The design dimensions of pulsating heat pipes are provided by design calculations.
