A heat exchanger for recovering the heat energy content in furnace waste gases and for recovering much of the dust entrained therewith includes a hollow duct through which the waste gases pass, and which contains first and second tube bundles arranged one after the other and a dust collection surface therebetween. The heat content in the waste gases is transferred to water passing through the two tube bundles and dust is deposited on the dust collection surface.

Heat exchanger for recovery of heat energy from dust-containing waste

The spaced apart elongated supporting members for the various tubular coils of a heat exchanger include vertically spaced apart openings in a wall portion thereof which faces an associated supporting member, the tubular coil being fitted to extend through the openings and thus be supported by the supporting members. A pair of such members, together with the supported tubular coil, comprise a heat exchange section, the entire heat exchanger including a multiplicity of such sections. Each individual section can be separately disconnected and removed from the heat exchanger if a leak develops in the supported tubular coil in a fast and efficient manner.
