Characteristics of Stamp Charging Coke and Top Charging,
Abstract. The characteristics of top charging coke (coke 1) and stamp charging coke (coke 2) were investigated. The weight loss ratios of two kinds of cokes with and without alkalis were measured after reacting with CO 2 under the temperature of 900, 1000, 1100 and 1200 °C respectively. The microstructures of original cokes were observed by SEM.Carbonisation Testing and Research,Stamp charge coke-making is commonly used in density variation programs and blending programs where higher densities of coal are required.
