Very small (5 to 10 micrometer) particle coal-water slurry fuel has been trialled in combined cycle gas turbine power plants.
[citation needed] In the late 1950s, the Soviet Union looked for new methods of using coal sludge for power generation.
The Belovo Novosibirsk project used coal-water slurry fuel in steam boilers at a rate of 1340 tonnes per hour.
[7] In 2012, the Austrian company, Effective Energy Technology GmbH (EET) built facilities for production and combustion of coal-water slurry fuel in Europe.
Examples of the technology in practice are hydroshock type wet-milling devices and standard water boilers equipped with swirl pre-chamber and coal-water slurry nozzle.,[8][9][10] developed by group of companies EET.
Verkhovna Rada requested China Development Bank credit for the implementation of coal-water slurry fuel technology.
