<p>PCT No. PCT/GB87/00851 Sec. 371 Date Jul. 27, 1989 Sec. 102(e) Date Jul. 27, 1989 PCT Filed Nov. 27, 1987 PCT Pub. No. WO88/04014 PCT Pub. Date Jun. 2, 1988.Heating apparatus for heating an environment comprises one or more heat exchange conduits (A, B, C, D, E, F, 6, 8) located in the flow path of primary heated fluid (F1-F2), and a device (4) for inducing a flow of air in each conduit, each conduit being adapted to carry air into, through and out of a heat flow path to the environment (2), the arrangement being such that, in use, air within the conduits progresses from a cooler to a hotter part of the heat flow path, and the conduits are spaced closer together toward the downstream direction of the flow path to improve the efficiency of heat exchange between the primary heated fluid and secondary air in the conduits.</p> |
