Coal Quality - Ash by Weight or Volume ?

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Certainly the grinding is going to reduce the volume but generally speaking a hand fired coal stove burns up the coal better. From my own experience the same exact load of buck used in the Van Wert produced the typical chunky granola type ash with a little bit of black in it while it burned up to powder in a Franco Belge.

I agree. The red ash I burned last year was much heavier than the white ash I have this year :D

It was ment as a joke,but iv'e been used to UAE coal and with this Blaschak coal it's more than twice the ash and half the heat,i'm very dissapointed :down:
Yes many of us were spoiled by the super low ash UAE Harmany but unfortunatley those days are gone. Wish I had stocked up with a TT load when it was available. :(

Edit: I suppose this is might be harder to observe in hand-fired equipment since the ashes are usually ground to a powder...but in a stoker it can be very easy to see. Probably the biggest difference I observed when running a hand-fed was how easy the stove shook down when burning coal that produced fluffy white ash.
Up until this year, for me to get three days of ash in the 6 gallon bucket, I often had to shake the bucket to compact the ash. Shaking the bucket is not needed this year because even four days of ash doesn't quite reach the top.

So, not only is the weight less, the volume is less too.

Think I'll call my coal dealer and see if he bought from a different breaker this year.

Lee,

A cooking hint. If ya stand that grill back up level, ya won't need to have the burgers stick to the grill. Then ya can use leaner chop meat. :D

Yeah, and Long Island's not an easy place to get rid of stuff nobody wants either !

Unless you come up with an idea like the young couple renovating an apartment in Brooklyn. Carting company wanted too much to haul it away, . . . so they boxed up the turn-out plaster and Christmas wrapped it. Then they left the boxes in the lobby.

Someone stole it all ! :D

Classic... :funny: . Your right about Long Island and their rules! Although my sanitation company is great, they take anything I put out for trash...no questions asked. Just don't let big brother see you!

I have the same supplier , same kind of coal (bagged blacshak ) but what a difference from last year. The rice coal last year was nice and clean and got a 10 % ash content , this year the coal has lots of fines and I have almost a 15 % ash content . I am going to try a few bags of buck and if that works out I know what I will be buying next year . Maybe I just got spoiled last year, fortunately the 110 burns it okay , just more of it and not just because it is colder this year .
