The gross calorific value of coke is largely controllable. It may be increased by optimizing the following factors: the volatile matter from the batch, the ultimate composition of the batch (taking account of oxidation), its granulometric composition, the packing density of the charge in the coking chamber, the temperature in the heating system, the coking rate, the coking period, the final coking temperature, the quenching method, and the size of the coke pieces.

焦炭的热值6.增加热值

焦炭的总热值在很大程度上是可控的。可以通过优化以下因素来增加它：批料中的挥发性物质，批料的最终组成（考虑到氧化作用），其粒度组成，焦化室中装料的堆积密度，加热温度系统，焦化速率，焦化时间，最终焦化温度，淬火方法和焦块尺寸。
