Harman Grate Edges and Ash Removal

Harman Grate Edges and Ash Removal

PostBy: Uglysquirrel On: Fri Jan 23, 2009 11:02 pm

With all the poking discussions though this is related.

Next time you have to stop your fire (Devill says never!!) take a look that the sharp edges formed in the casting process between the top surface of the grate and the ash slots. There seems to be absolutely no radius. Was a thinking a nice approx .030 -.050" radius on the ash slot edges would help ash slip thru a lot easier while still holding the coal back. Getting rid of the sharp edges would also extend the grate life by lowering the stress risers at the edge.

This is could only be done on the hottest of summer days with an air grinder while sing Christmas songs after a case of beer. And wind that grinder up next to your neighbors bedroom window at 9 pm.

Waz the vote, you think this maybe is worth a try ?

Rounding over the edges may help the ash drop through but may also allow klinkers to get stuck. I would think the sharp edges would help crush and break up the klinkers and unburnt pieces of coal letting them fall through rather than jam the grates. I haven't looked at mine to see if the edges are sharp or rounded but would expect all grates from the company to be the same. Just my 2 cents.

Uglysquirrel, I think you should just sit down and have another a beer, all that grinding sounds like way too much work for any possible benefit. besides the sharp edges helps break up the clinkers easier.

I am new to coal burning but the design you state may be intentional . Maybe to help brak up stuck coal better.

I have to agree with the others......Sounds like too much work for a small, possible benefit.
