    High-volatile coal burns a lot like plastics which heat up and off gas. This volatile gas reacts, standing off some distance from the individual particle, which then contributes to the flame front and propagation. Low-volatile coal reacts more like carbon. The reaction will be on the surface, burning the oxygen in the air with the solid carbon.

  • Coke (fuel) - Wikipedia

    The industrial production of coke from coal is called coking.The coal is baked in an airless kiln, a "coke furnace" or "coking 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 process vaporises or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.
