ABSTRACT:
An open-cycle absorption apparatus for compressing steam from a low pressure to a higher useful pressure is disclosed. The apparatus is particularly useful for upgrading low-temperature jacket-cooling heat from an internal combustion engine to useful pressure steam, e.g., at 5 ATA (500 kPa) or higher. Simple heat-exchange apparatus is involved, using the extra temperature availability of the hot exhaust gas as the driving medium. In FIG. 1, hot exhaust gas heats absorbent solution in desorber 7, and then the absorbent solution absorbs low pressure steam from the jacket cooling circuit of engine 1 in absorber 14. Useful pressure steam is withdrawn from desorber 7 and from steam generation coil 16 in absorber 14.
