Are you referring to big ash chunks at the end of the grate ??
Sounds like klinkers to me. Are you burning harder than normal ??
Did you switch brands of coal ??
Are you blowing more air up through the grate ??
Try increasing the amount of feed or decreasing the amount of air. Klinkers form when coal burns really hot and fuses together. It is also possible that the end of the grate has become rough and not allowing the normal flow of ash to take place. IOf you can, shut it down and do a thorough cleaning. Make sure the air holes are all opened up. Run a couple passes of 80 grit sand paper across the end of the grate. Refire it and see if there is any change and report back to us.
