In the 1850s, processes for making producer gas and water gas from coke were developed. Unenriched water gas may be described as blue water gas (bwg). Mond gas, developed in the 1850s by ludwig mond, was producer gas made from coal instead of coke. It contained ammonia and coal tar and was processed to recover these valuable compounds. Blue water gas (bwg) burns with a non-luminous flame which makes it unsuitable for lighting purposes.

The normal green coke is used as a fuel, where it can be more convenient to use than fuel oil because its properties are sufficiently similar to those of coal that coal/petcoke mixtures can be used in power generation or cement manufacture in whatever proportions desired without major modifications to plant.
Coal is baked in an airless furnace at a very high temperature (above 2000 degrees celsius) to remove water, gas and coal-tar, and at the end of the coking process, it contains zero amount of water. However, later small amount of water can be absorbed by the porous structure.
Coal utilization, combustion of coal or its conversion into useful solid, gaseous, and liquid products. By far the most important use of coal is in combustion, mainly to provide heat to the boilers of electric power plants.
Date: february 17, 2021 coke ovens are special devices that turn coal into coke. A coke oven is a device used to produce coke, a product that is derived from coal. The mixing and heating of bituminous coal at temperatures ranging from around 1832° to 3632°f (1000° to 2,000°c) within the airless oven yields the coke byproduct.

The quantity of oxygen is limited to prevent complete combustion of the coal. Instead, the carbon reacts with the steam to form a mixture of co, h 2, and other gases. At these temperatures, the sulfur compounds from the coal react with some of the hydrogen gas to produce h 2 s and some.
Coke is a carbon-rich solid that is produced by the pyrolysis of blends of low-ash coal and low-sulfur. The process is known as coking and it is performed to get rid of the volatile components of coal, leaving behind the fixed carbon and an ash residue in the form of a gray, porous solid.
