Firing facilities for technological wastes and by-products

Because of the significant price increase of energy carriers and due to the more stringent prescriptions of environmental protection standards, the demand for thermal disposing and reutilisation of hazardous materials of industrial technologies has been increased (such as blast furnace gas, chamber gas, waste gases of chemical industry, aggressive flue exhaust gases of chemical industry, rest of solvent-air mixtures, gases of high inert content, liquid wastes, exhaust oil, tar etc.).

Development of these special burner constructions had been made on the basis of the series manufactured boiler burners and furnaces of TÜKI.

The thermal elimination of by-products of industrial technologies which does not content any aggressive components as well as burning of homogenous liquid wastes generally takes place in boilers or similar heat utilisation facilities in using heat recovery.

These by-products are frequently not perfectly cleaned or its pressure is not stabilised. For this reason the design of these appliances should be performed in such a way that the harmful effect of powder and moisture reaching the firing facility has to be avoided.

The combustible content of waste gases is generally some type of hydrocarbons, depending on the applied technology, as well as CO and H₂. Due to this feature the combustion characteristics of waste gases are very different and design of the applied burning facilities are also different.

There are homogenous and nonhomogenous liquid or gaseous hydrocarbons of various pollutants, by-products and wastes which can not be burnt even with special burners in generally used combustion chambers of industrial firing technics. For their disposing special designed equipment, so-called incinerators have to be applied.

In the field of thermal disposing and reutilization of various wastes and by-products TÜKI gained experiences of many years realising these facilities.
