The pool nucleate boiling heat transfer characteristics of 10%, 20% and 30% lithium bromide solution was studied in the paper with Polyethylene Glycol Octylphenol Ether as an additive. The results showed that the additive can significantly reduce the surface tension of lithium bromide solution and different concentrations of the solution have its own CMC. The additive can enhance boiling heat transfer. The extreme characteristic strengthening effect was shown. The optimum concentration of heat transfer enhancement was about at CMC of the corresponding concentration of lithium bromide solution. With the improving of lithium bromide solution concentration, the additive effect of heat transfer enhancement was slowing and this trend tends to gradually decrease.
