From Wikipedia, the free encyclopedia Main article: Coke (fuel). Coke is a solid carbonaceous residue derived from lowash, lowsulfur bituminous coal from which the volatile constituents are driven off by baking in an oven without oxygen at temperatures as high as 1,000 °C (1,832 °F) so that the fixed carbon and residual ash are fused together. . Metallurgic coke is used as a fuel and as a ...
