This paper reports some important results of an experimental investigation carried out to study the heat transfer coefficients during pool boiling of lithium bromide-water solutions over horizontal stainless steel tubes. An experimental setup was fabricated to conduct the experiments and data were collected in a heat flux range of 15 to 108 kW/m[sup 2] system pressure of 4 to 9.93 kPa and for a three-fold variation in the lithium bromide mass concentration. Three stainless steel tubes of different diameters were used as the test lengths. The study of the local and average heat transfer coefficients indicated that the boiling phenomenon is not significantly affected by tube diameter. The solution concentration is a dominant factor and as it increases heat transfer coefficient decreases and the local heat transfer coefficients decrease especially at sides and bottom.
