The coal is piled on the ground up to 10-12 m height. During storage of coal in heaps, the coal should be compacted in a layer of 15 to 30 cm in thickness by means of bulldozers and rubber-tired scrapers. This effectively prevents air circulation in the interior of the pile.
Coke (fuel) - Wikipedia
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

The ratio of the two equations. At room temperature both oxygen and nitrogen exist as diatomic molecules, O2 and N2, respectively. It is usually assumed that the nitrogen in the air is nonreacting at combustion temperatures; that is, there are as many moles of pure nitrogen in the products as there

The two main advantages of this process are its ability to create very complex cross-sections and work materials that are brittle. The extrusion process can be done with hot or cold materials. Commonly extruded materials include metals, polymers, ceramics, concrete and foodstuffs.
Benefits of Renewable Energy Use | Union of Concerned Scientists
Although renewable facilities require upfront investments to build, they can then operate at very low cost (for most clean energy technologies, the "fuel" is free). As a result, renewable energy prices can be very stable over time. Moreover, the costs of renewable energy technologies have declined steadily

Additionally, PPS has excellent resistance to both acids and alkalis. The media also has the ability to operate effectively on applications with O2 content up to 9%. PPS works well in high moisture content applications and where dew point crossings are common. This media is suited for applications where emissions standards are tight.
