Afternoon all!

I was at my local saw mills the other day and asked if they sold wood for my log burner, they didn't however the friendly chap gave me a box of the below..

He said they are 'hardwood pellets', offcuts from the cutting they do but didn't really know what from.

I don't want to put anything in the burner that is going to ruin it.

They chuck a bunch of these in there industrial one to heat the shop floor and unit but the burner is industrial so doubt it is that sensitive to the liner get blocked up with chemicals.

Any idea what it is and if they are ok to burn?

are they compressed wood fibre? Or are they solid discs like a hole-cutter makes, e.g. if you were cutting holes for dowels, or to knock into the countersinks to hide screw heads?

The size might be a clue. They do look to me rather like compressed fibre, but I don't know a machine that would throw them out. Maybe a morticer? The colour suggests red tropical hardwood, such as front-door sills so I'd think OK in your woodburner.

They look bigger than the pellets used in a normal stove.

They look more like a compressed wood fibre to me. They don't have a natural grain at all.
 
so perhaps they're compressed out of sawdust and chips, to make a better fuel.

Potentially yeah. They aren't bespoke made fire wood though.

He gave them me as scraps, effectively they are a bit product of some process they go through at the mill, off cuts if you like.

I'm thinking if they have been compressed it's likely there is some chemical to hold them together and so unlikely to be good to burn in the stove.
 
They are just compressed shavings and dust held together by the resins in the shavings
Here’s a picture of the machine that makes them, you tend to find the more sawdust in them the more crumbly they are but they do burn well if sometimes a little hot
