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...
