摘要

Heat generated by chemical reaction within a fuel storage/reaction chamber (14) is transferred to a heat exchanger (12) having means (22, 24, 26, 28) for conveying a working fluid, by means of an expandable heat transfer member (16) which can be inserted within an annular gap between heat exchanger (12) and chamber (14) when in contracted condition, and expanded into a condition wherein its outer surface (42) contacts the inner surface (40) of heat exchanger (12), and its inner surface (44) contacts the outer surface (46) of chamber (14). After generation of heat by chemical reaction, chamber (14) can be removed for disposal or renovation, by contraction of said member (16), whereby to break contact between said surfaces (40, 42, 44, 46).
