2. Coal gasification
By its very nature, combustion is a set of phenomena taking place in the gaseous phase. When the fuel is not gaseous, combustion is preceded by a stage of transformation into a gas through evaporation, pyrolysis and partial oxidation. In conventional pulverized coal burners, gasification and gas combustion are not dissociated, and only a global phenomenon is observed.
History of gasification
The idea of separating the gasification and combustion phases is a relatively old one. According to available historical data, coal gas production was first used in England in 1792. As early as 1812, the first coal gasification company was set up in London. Baltimore was the first city to develop a coal gas distribution network in 1816, mainly for street lighting. The use of coal gas expanded considerably around the...

Manufacturers (non-exhaustive list)
The construction of an IGCC plant generally involves three manufacturers, one for each of the main islands: gasifier, combined cycle and air separation unit. Tables 1 ,
Operators
Table 4 shows the main operators of industrial-scale IGCC power plants in operation or under construction worldwide. This list is likely to grow in the near future, as all utilities are likely to equip themselves with IGCC plants, since this is one of the clean coal technologies....
