This invention provides a method for evaluating the cost-effectiveness of semi-coke based on the effective calorific value of pulverized coal, relating to the field of iron and steel metallurgy. First, a formula for calculating the effective calorific value of pulverized coal in a blast furnace is established. By calculating the heat released from incomplete combustion of carbon and deducting the heat absorbed by moisture decomposition, hydrocarbon cracking, ash slag formation, and desulfurization, an effective calorific value more consistent with the actual operating conditions of the blast furnace is obtained. Subsequently, this effective calorific value is divided by the injection cost to construct a cost-effectiveness index. By calculating and comparing the cost-effectiveness index of the target fuel combination after semi-coke partially replaces anthracite with the benchmark combination cost-effectiveness index, the economic viability of semi-coke substitution can be accurately determined, and the critical price or price range for cost-effective semi-coke can be directly calculated. This invention overcomes the shortcomings of traditional evaluation methods that are detached from the actual thermal environment of the blast furnace, providing a scientific and quantitative decision-making basis for fuel procurement and coal blending optimization.
