Pulverized Coal Pipe Testing and Balancing

Coal pipe F9 on pulverizer B was the only pipe that met the original plant fuel specifiion guarantee of 70% passing 200 mesh, which is far short of the 75% minimum we use. Even so, fuel fineness and fuel distribution overall was poor, and it resulted in slagging, fouling, and higherthandesirable fly ash LOI.
