METHOD OF ENRICHMENT OF ALTERNATIVE, CARBON-CONTAINING, LOW CALORIE WASTES FOR USE IN FURNACE PLANTS Russian patent published in 2014 - IPC C04B7/44 F23G5/00 

FIELD: heating.

SUBSTANCE: invention relates to a method of enrichment of alternative, carbon-containing, low calorie wastes for the production of synthesis gas for use in furnace plants. The method comprises the high temperature gasification of alternative fuel under conditions preventing oxidation, at temperatures above 1000°C. And water, water steam or CO₂ is supplied through nozzles, thus providing recovery of CO and H₂. For high-temperature gasification the waste heat of a clinker cooler is used, through a heat exchanger, which is used as double walls of a rotary tube furnace or heat-resistant heat accumulators, which is mixed with the heated fuel. As the heat-resistant heat accumulators used are, for example, sand or ceramic particles. The heat-resistant heat accumulators are additionally used as a partial amount of the clinker supplied into the clinker cooler.

EFFECT: reduction of the thermal and operational load when effective fuel combustion and improvement of the quality of the fuel gas.
