Along - term change of nucleate boiling heat transfer coefficients in water and ammonia/water mixture has beenmeasured when a surface - active agent was added into water and the mixtures. The experiment has been carried out
using a thermosyphon with a plain heated surface and a pool boiling vessel with a heated fine wire. The effect of thesurface - active agent on a long - term change was investigated experimentally for the surfactant concentration, CS = 0and 1000 ppm and ammonia fraction, C = 0 and 0.2 and time variation of the boiling heat transfer coefficient wasmeasured for about a month. The result shows that the nucleate boiling heat transfer coefficient has never changed fora month for pure water. On the other hand, the boiling heat transfer coefficient increases suddenly in the midst ofoperation and then lasted a constant value till the end of operation for both water and the mixture with the surfactant.
