Abstract

A combustion device comprising a plurality of regenerative units formed by a plurality of separate radially extending compartments each containing a plurality of corrugated highly conductive metal plates compressed together with the corrugations in the adjacent plates intersecting each other at right angles so as to provide meandering passages for the gases between the adjacent corrugated plates; a rotary switching valve provided at one end of said regenerative means for controlling the flow of said waste gases flowing therethrough; a reaction zone provided at the other end of said regenerative means in which said waste gases are reacted; and a temperature-adjusting chamber located within said reaction zone and provided with an auxiliary combustion burner and an excess-heat disposal branch conduit.
