Current status and development trend of pulverized coal industrial boilers in China

in order to improve the coal combustion eficiency of pulverized cal industry boler.reduc e the emission of aolltants the six core fechnologies of pulverized coal industrial bolies inclucing pulverized coal preparation and transportation,puverized coals aility and storage technology dense- phase pulverized coal onveyng technology.pulverized coal burner,boler bodylow emisson fue gas purification techmnology were inroduced in deali 'he paper pointed out some problems existed n the operation process .such as unstable fed.low burning rate combustion difiultis and high emissions.
