    Dec 01, 2016 In the initial stage of carbonization, a strong shell of coke is formed on the outer surface of the briquette, which helps to restrict free swelling of the inner coal. Therefore the briquetted coal is apparently carbonized at the density of between 1150 and 1180 kg/m 3 , which contributes to form strong bonds between coal particles, resulting in strong coke
