<p>An absorption chiller (2) including a generator (4) to boil-off water from a lithium bromide/water solution. The generator (4) comprises an upper tank (42) and a lower tank (36) interconnected by vertical heat exchange tubes (38) which are disposed in cross-flow relation with the hot products of combustion coming from a fuel gas pre-mix package burner (50) and flowing through a combustion chamber (46) and in which the solution flows upwardly, and by insulated thermo-syphon tubes (58) which are separated from the hot products flow by a thermal barrier and in which the solution flows downwardly. The weak solution is introduced into the upper tank (42) through an inlet (68) opposite the upper end of a thermo-syphon tube (58). The upper tank (42) comprises baffle plate (76), a demister pad (74), an outlet (72) for steam, vertical baffle plates (80, 82) forming a calm zone (78) and an outlet (70) for concentrated lithium bromide.</p> |
