Use of resin-bearing wastes from coke and coal chemicals production at the Novokuznetsk Metallurgical Combine

The coke and coal chemicals plant at the Novokuznetsk Metallurgical Combine is making trial use of a technology that recycles waste products in “tar ponds.” Specialists from the ékomash company have installed a recycling unit in one area of the plant’s dump, the unit including an inclined conveyor with a steam heater and a receiving hopper. The coal preparation shop receives the wastes in a heated bin, where a screw mixes the wastes with part of the charge for the coking ovens. The mixture subsequently travels along a moving conveyor belt together with the rest of the charge materials. The addition of up to 2% resin-bearing waste materials to the coal charge has not had any significant effect on the strength properties of the coke. __________ Translated from Metallurg, No. 4, pp. 49–50, April, 2007.
