PROCEDURE FOR EVALUATION OF OPTIMAL COMPOSITION OF COAL CHARGE FOR COKING Russian patent published in 2011 - IPC C10B57/04 G01N33/22 

FIELD: oil and gas production.

SUBSTANCE: coal charge for coking consisting of several components is coked with different content of coke and sintering components. There are determined coefficients of optimality and optimal composition of coal charge for coking. As coke components there are used coking coal of 1 and 2 classes, and as sintering components there are used coals of fat grades. Coefficient of optimality of charge is calculated by formula: K_opt=K₁*K₂*K_sint*100; where K₁ is coefficient of deviation from optimal content of coking coal of 1 class; K₂ is coefficient of deviation from optimal content of coking coal of 2 class, K_sint is coefficient of deviation from optimal content of sintering coals.

EFFECT: production of coke with specified strength properties, prognosis of coke strength on base of optimality coefficient.
