Coal Pulverizer - Pall

1 天前  Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

COAL PULVERIZER DESIGN UPGRADES TO MEET THE

2010-7-27  Coal pulverizer design and operation is an important element integral to the long termsuccess of Low NOxcombustion systems. The increased use of Low NOxburners in thepast 10 years has instigated a need for further development of coal pulverizer technologyin an effort to ensure efficient operation of a power boiler for minimizing gaseousemissions (NOx, CO, HC) and unburned carbon in fly ash. Riley Power Inc. (RPI), aBabcock Power Inc. company, has been developing improved coal pulverizer technologyduring the past several years to meet these challenging demands. All three (3) types ofcoal pulverizer systems supplied by RPI originally designed for low, medium and high-speed pulverization have undergone design upgrades and improvements. These machinesinclude Ball Tube Mills (BTM), MPS mills and Atrita®Pulverizers, respectively. TheAtrita®Pulverizer has been upgraded for better coal fineness and longer service life. BTMsystems have been upgraded for more reliable operation
