The coal gasification rate of Datong coal in molten blast furnace slag using carbon dioxide as gasifying agent was studied at the temperature ranging from 1473 to 1723 K. The kinetic model was

The blast furnace BF slag waste heat was recovered by an integrated system stage by stage, which combined a physical and chemical method. The water and coal gasification reactions were used to recover the heat in the system. Based on the first and second law of thermodynamics, the thermodynamic analysis of the system was carried out by the enthalpyexergy diagram

2015-1-9Boiler slag n. melted coal ash. Few people have heard of coal ash. But U.S. fossil fuel plants produce 140 million tons of the stuff every year in the process of combusting coal, making it the

2017-2-6coal in a furnace slowly heated to 800C. The ratio of coke ash, coal ash and fluxes used in the specimen varies depending on coke rate, and the amount of coal and fluxes injected. Table 1 shows the amounts of fluxes to be injected corresponding to different injection levels. To make a specimen representing the tuyere slag at a certain level
