Abstract
In a self-designed experimental apparatus, coke oven gas, H2, CO, CH4, CO2, and N2 as coke dry quenching medium, coke as the bed filler, and the influences of particle shape, particle size, the gas flow, and gas species on the bed pressure drop characteristics were investigated. Furthermore, the mathematical model of coke bed pressure drop of coke dry quenching by coke oven gas was established. The results show that coke bed pressure drop increases with the increasing of the gas flow and decreases with the coke particle size increasing. When the gas flow is larger and the particle size of the coke is smaller, the coke bed pressure drops obvious change. It was also found that the coke bed pressure drop has a direct relationship with gas properties, such as density, viscosity, and so on. For the different gas (H2, CO, CH4, CO2, and N2) in the same bed thickness of coke, the order of bed pressure drop has the following relationship: PCO2 > PN2 ≈ PCO > PCH4 > PH2. Under the coke oven gas as coke dry quenching...
