Coke (fuel) - Infogalactic: the planetary knowledge core
2021-8-21 · Volatile constituents of the coal—including water, coal-gas, and coal-tar—are driven off by baking in an airless furnace or oven at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This fuses together the fixed carbon and residual ash. Some facilities have "by-product" coking ovens in which the volatile hydrocarbons are mainly used ...
