The prepared coal is charged into carbonization chambers by a larry car. The coals in the carbonization chamber are carbonized by heat transferred from the combustion chamber. When the coking process is completed, the oven doors are opened, the pusher is spotted opposite the pusherside door, and the hot coke is forced out of the oven by means of

Carbonization, more narrowly defined, refers to conversion of a starting material into carbon, or a carbonrich solid. It is entirely possible, and indeed often done, to pyrolyze a hydrocarbon feedstock for the purpose of carbonization, but carbonization is not simply pyrolysis by another name.

Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2. A gaseous byproduct referred to as coke oven gas (COG ...

As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since it was formed from the remains of vegetation, coal is also called a fossil fuel. The fossil fuel such as petroleum is formed from the dead animals under the sea. As these organisms died, their bodies settled at the bottom ...

Carbonisation is a promising process to upgrade low rank coal briquettes to clean coal, where the shape of briquettes in the carbonisation reactors may be significantly different, including sphere, ellipsoid, cylinder, halfellipsoid. However, the influence of briquette shape variation on carbonisation performance has not been studied.

This chapter discusses coal carbonization. Coal carbonization involves the destructive distillation of coal, and during this process, as much as 50% of the weight of the coal feedstock is driven off as gaseous and volatile components. These are regarded as byproducts of the coking process, and include combustible gases (for example, methane ...
