The science behind forced log drying

I think around 100 depending how wet when it goes in but it's hard to work out because we also dry chip which is less efficient. I'll try to have a work out some time, I usually only work it annually so that could be way off.

100!? I meant energy in the fuel!

 

based on around half a ton / m3 I'd imagine around 5-6000 kWh depending on boiler efficiently!

Oh sorry, that's to dry it. Not sure for firewood but I would think a lot less than that. 

 

We tried selling some at 8p a kW and it wasn't quite making £60 a cube. It's too late to backwork that now

Can you share the break down for that please.

 

what do use for drying

Previous posts on Arbtalk have discussed the costs of drying in detail. A realistic cost appears to be circa. £ 10/ m3 buying in Softwood to dry then burning as boiler fuel without RHI as I don't think everyone factored in the true amount of labour involved, purchase and replacement of equipment and all associated running costs.

 

If you are in a rare situation where Tree Surgeons bring you free Arb arisings, which you can keep for a long time to be dry enough to burn of course this estimate would be reduced. Rings can however take up to 2 years even in stillages to reach even 25% MC.
