ABSTRACT:
The wet method of combusting organic material dispersed in a liquid comprising waste liquor from wood pulping processes in which the organic material is oxidized by contact with air or other oxygenating gases at a temperature ranging between 180.degree. C. and 340.degree. C. and a correspondingly superatmospheric pressure. The combustion of oxygenation is carried out in two steps: namely, a first step in which the organic material is partially oxidized so that the major portion of the organic substances is converted into carbon dioxide and water, and a minor portion is converted to water-soluble low-molecular fatty acids resistant to oxidation; in a second oxidizing step, the residual oxygen-resistant fatty acids are combusted in the presence of a substantial excess of oxygen-enriched air or other molecular-oxygenating gas so as to liberate the total heat of combustion of the organic material and to impart to the resultant gaseous mixture of effluents a molecular oxygen content sufficient to achieve the partial oxidation in the first step.
