ANGPANNA ELLER VERMEVEXLARE FOR ENERGIATERVINNING UR GASER INNEHALLANDE STOFT

摘要

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.
