the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. After leaving the coke oven chambers, the raw coke oven gas is cooled which results in a liquid condensate stream and a gas stream.

بیشترWhen coal is carbonized in a coke oven chamber to pro-duce coke, the gas in the plastic zone of the coal exerts pressure (coking pressure) on chamber walls,1–3) which varies depending on factors, such as the brand and the bulk density of the coal in the chamber. When the pressure is high, chamber walls may suffer heavy damage,1–3) and the
بیشترCoking proceeds for 15 to 18 hours to produce blast furnace coke. During this period, volatile matter of coal distills out as coke oven gas. The coking time is determined by the coal blend, moisture content, rate of under firing, and the desired properties of the coke. When demand for coke is low, coking times can be increased to 24 hours.
