Abstract

Combustion of moist residue from paper. The residue is subjected to a fast stage oxidn. with compressed air; the inert gases and gaseous oxidn. products of the partly oxidised liquid phase are separated in which the partial pressure of the inert gases are reduced to create a balance with the partly oxidised liquid phase; then the partly oxidised liquid phase is subjected to a second stage oxidn. with compressed air. Flow of air and liquid in the first stage is parallel, in the second stage counterflow
