STEAM GENERATING EQUIPMENT

PROBLEM TO BE SOLVED: To lessen the area of installation and to reduce the quantity of holding liquid. SOLUTION: A high temperature regenerator as steam generating equipment has an outer tube 1, an inner tube 2, a passage 3, a vapor-liquid separating part 9, etc. The inner tube 2 has a lower part 2a constructed of a straight tube forming a combustion chamber 4, an upper part 2b constructed of a bellows tube, etc. An absorbent liquid which absorbs a refrigerant is made to flow through the passage 3. Accordingly, the lower part forming a radiation heat transfer surface and the upper part forming a contact heat transfer surface are provided upright in a straight line and, therefore, an installation space is minimized. Since a space between the inner and outer tubes is made the liquid passage, the holding amount of liquid is reduced and the equipment cost is also reduced. Heat exchange is facilitated in the part of the bellows tube and a necessary amount of evaporation is ensured.
