WEBCoal ribboning, or roping, naturally occurs inside of the remote classifier due to traveling through the mill piping and classifier system. If these ribbons of heavy fuel are allowed to continue thru the upper turret section, they will cause very unbalanced air/fuel ratios and a high deviation of fuel distribution across the discharge pipes.
