Abstract
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.
Claims16
Heating apparatus for heating an environment comprising:
- a container means having inlet and outlet means and defining a flow path for heated fluid;
- a plurality of heat exchange tubes disposed in said container means substantially transversely to said flow path and in spaced relationship in the direction of flow of said flow path, said tubes forming at least a part of at least one heat exchange conduit means for the flow of secondary fluid to be heated therethrough and having an inlet and an outlet;
- and
- fluid flow inducing means operatively connected to said at least one conduit means for inducing a flow of secondary fluid therethrough from said inlet to said outlet thereof;
- said tubes being spaced so that the spacing between adjacent tubes gradually decreases in the direction of downstream flow of said heated fluid in said flow path so that the flow of secondary fluid through said tubes is balanced and said heated fluid is progressively compressed between said inlet and outlet means of said container means and the temperature of said heated fluid is increased in said downstream direction for improving the rate of heat exchange between said heated fluid and secondary fluid.
