Summary

Heat transfer performance of forced convective boiling in high-temperature generators was experimentally studied using an actual absorption chiller-heater. Measurements were made at six locations, three different levels on a couple of laterally separated lines, for the fluid rising along the rear wall of the high-temperature generator furnace. Fluids tested were water and lithium bromide aqueous solution. It can be suggested that satured boiling occurs within a comparatively narrow area, located at the upper zone of heat transfer surface of the generator, while forced convective heat transfer and subcooled boiling appear at the remaining broad area. Enhancement of heat transfer due to saturated boiling was not more pronounced for lithium bromide aqueous solution than for water.
