ABSTRACT:
In a high-temperature regenerator of an absorption refrigerator according to the present invention, the longitudinal cross-sectional area of a portion of a combustion chamber parallel to the surface combustion plate is given a shape that is narrowed to a size equal to the surface area of the fire hole towards the downstream side from a surface combustion plate. As a result, a pipe wall of the combustion chamber protects the vicinity of the fire hole. Since this pipe wall contains absorption fluid flowing through it in the form of convection flow, it does not reach high temperatures as in the refractory material of the prior art, thereby being able to avoid the problem of increased NOx values. In addition, the problem of the prior art of inhibiting heat transfer to pipe wall is also eliminated.
