The invention provides fuel for sintering ingredients and an adding method of the fuel. According to the fuel for the sintering ingredients, one of semi-coke and CDQ powder is used, or a mixture of the semi-coke and the CDQ powder is used, and in use, the mixture comprises 40-80% wt% of the semi-coke and 20-60% of the CDQ powder. The fuel is put into a fuel bin of an ingredient workshop and put onto a belt through a disc feeder; the fuel is evenly mixed with other kinds of ore and a fusing agent through a primary mixing machine and a secondary mixing machine; then the mixed material is put on a sintering trolley through a distribution device, and sintering production of the mixed ore is conducted; and the adding amount of the fuel in the mixed material is worked out according to the formula of RL=K1+QT*K2+YHG*K3+EYHG*K4+SF*K5+GD*K. By the adoption of the fuel, the fuel dosage can be adjusted flexibly according to the different core conditions during sintering, mixing and bending, so that the carbon blending cost per ton of the mixed ore is lowered by over RMB 1 yuan, the low cost of the ore blending for sintering is achieved, and the quality of the sintered ore can be improved effectively.
