Abstract: 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. Atlast.some suggestions were put fowar to ensure saetyand stale operation of ulverized coal industry bolie . The dense- phase igntion semi coal gasication combustion in fame stablirer and mid combustion in the furnacein order to stablize the combustion and fame spread. ks for the paliution controls it as suitable to adopt dust catcher by mechanical forcecombined with flir dust separator as wel a fractional low NOxcombustion coupled with SNCR(selective non- catalytic reduction) denitration and semi- dry desufurization technologies
