PERFECCIONAMIENTOS INTRODUCIDOS EN UN RECUPERADOR.

摘要

A recuperator which includes vertically extending outer tubes and respective inner tubes within the outer tubes. Hot waste gases flow around the outside of the outer tubes. Air to be preheated flows through the inner tubes and annular passages between tubes. The outer tubes are formed of relatively short length sections of ceramic joined end-to-end. The lowermost sections rest on solid base blocks which support the weight of the outer tubes.
