Coal Water Slurry is an enviromental friendly form coal combustion on power stations. CWS is classified as a clean coal technology because of serious reduce of emissions like SOx or NOx and CO2 plus to effective and low-cost ash utilisation.
Combustion of coal on power stations allows to rich maximum level of coal combustion (no less than 99%) not only high-volatile coals but even also for anthracites.
Usage of CWS instead of regular pullverised coal combustion reduces an impact of initial raw coal to combustion process, e.g. simplifies migration from one coal type to another.
