A method is presented for purification of waste gases in various industrial enterprises from impurities, mainly organic ones. The method can be used for purifying the waste gases generated in the production of synthetic fat substitutes, dyestuffs, antibiotics, synthetic fibers and other products of organic synthesis and for purifying the waste gases liberated in the process of oil refining, drying of coatings, and smoking. The method consists of burning the waste gases in the furnaces of boiler units including those whose main function is generation of thermal and electrical energy. The waste gases to be purified are delivered under, or into the beginning of, the fuel burning zone instead of part or all of the air required for the combustion of the fuel. The main disadvantage of the prior art involved a considerable consumption of heat energy for heating the waste gases to 800 C and above, and a low degree of purification of waste gases. 5 references.
