You should be soo proud
I did not know they could get that large without raising hell with your grates.
... There is a ledge on each side of the grate frame where ash seems to nest, where it can sit there and fuse. The clickers also seem to form on top the grates somehow. I think the excessive fines have a hand in the clicker formation too, but maybe its just the red ash coal that's the culprit. Never seems to bother the grates. Since the clickers seem to stay suspended in the coal bed.
I have the same style firebox as you,take your "clinker fishing tool" with the angle and scrape/push/pull along the sides of the angled firebrick and push the acculimated ash down toward the ash pan,that works for me.
I have UAE nut coal and it's very easy to produce clinkers
if burning hot.I have reduced the combustion air by 50% and the clinkers
have stoped.I used to have clinkers
12" long and 5" thick sticking to the cement blocks that reduce the firebox.
The smaller clinkers
get ground up with my triangler roller grates.
