Steel Production
Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.

How to Smoke Fish Recipe
Smaller fillets only need 12 to 15 minutes, and larger, thicker cuts of fish 20 to 30 minutes. Though we love the flavor of smoke, longer isn't always better. In this case, the delicate fish can dry out if left in the hot grill for too long, and its mild flavor absorbs plenty of tasty smoke in a short amount of time.

The research proposed an innovative, efficient, and clean process which used low-rank coals and oxidized pellets as carbon-based feedstocks and activators for one-step preparation of activated carbon with direct reduction iron as co-production. The co-effect between low-rank coals and oxidized pellets was disclosed.
Advanced Guide: How Does Coal Energy Work
The burning coal heats water in a boiler, creating steam. Steam from the boiler spins the blades of an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine. The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy.
6 Ways to Smoke Meat
This is an important step to take before you begin smoking any type of meat. It will ensure that the meat cooks evenly and reaches the right internal temperature by the end of the cooking process. Depending on how large your cut of meat is, set it out on the counter about 1/2 hour to 2 hours before you begin smoking it. [15]
