Abstract
A heat exchanger for cooling a hot, high pressure gas and utilizing the heat removed therefrom for generating hot water comprising a first and a second vertically elongated pressure containment vessels, the second vessel disposed coaxially within the first vessel so as to establish an annular space between the outer surface of the second vessel and the inner surface of the first vessel. A gas inlet pipe penetrates through the bottom of the first vessel opening into the second vessel at the bottom thereof and a gas outlet pipe penetrates through the top of the first vessel opening into the second vessel at top thereof, thereby providing a passageway for the hot gas to flow through the second vessel. Water is circulated through the annular space between the first and second vessels and heated therein as it absorbs heat lost by the hot gas passing through the second vessel.
