consumption of coke in gypsum millingising process

Coke Consumption an overview | ScienceDirect Topics

Consumption of reducing agents and fuel in German blast furnace ironmaking [ 35 ] It can be seen that in 1950s only coke was used for blast furnace process, and coke consumption was as high as 950 kg/THM Along the technology development, the coke consumption has been reduced to 500–550 kg/THM during 1970sReduction of Coke Consumption in HighTemperature Gasifying and Direct Melting System lar, these tests confirmed that it is possible to replace 100% of conventional coke with biomass solid fuel, in other words, to operate without using conventional coke, by using wood briquette charcoal or a combination of this material and rice husk briquettesReduction of Coke Consumption in HighA flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11161 In this process gypsum is crushed, dried, ground, and calcined Not all of the operations shown in Figure 11161 are performed at all gypsum plants Some plants produce only wallboard, and many plants do not produce soil1116 Gypsum Manufacturing US EPA

122 Coke Production

The primary purpose of modern coke ovens is the production of quality coke for the iron and steel industry The recovery of coal chemicals is an economical necessity, as they equal approximately 35 percent of the value of the coal To produce quality metallurgical coke, a hightemperature carbonization process is usedby about 1015%, ie, to roughly 400 kg, by the use of other energy carriers, and could be cut further by the use of prereduced ore 3 Because of the improvement effected in the Moeller process, small coke, which was formerly used for domestic fires, is being used more and more inReport on the question of coking coal and coke for the
