BSL Volume Calculation

[MonsterMonster]

There's been a few threads about volumes of wood regarding bags, expected cubes per tonne etc. where the general response is that we all get something different. Well here's a spin on that one with the BSL quarterly reporting based upon volume (or tonnage).

 

Bearing in mind I do not have any scales to weigh tonnes I'll have to report based on volume. But what basis is this volume calculated; loose split load, stacked split, solid pre-split wood with no air gaps? The difference in volumes could be up to a factor of 2.5 roughly.

 

I contacted the BSL and they don't know and it's down to me to determine it. In that case I shall calculate the pre-split stacked wood with 30% less for airgaps giving me the lowest figure possible.

We have a chip boiler so we either know how many tonnes were in the wagon load that was delivered or we know the volume of our chip store if we're chipping it straight into the store, no chance of weight measurements there.

 

In your case I'd do exactly as you have suggested.

I rather doubt they'll ever have the interest, competence or assets to attempt anything other than a cursory desktop audit so I can't see the worry beads being deployed any time soon!

I would have thought that they will have a pretty good idea of how much fuel/timber has been used by the your meter readings.

That's how I calculate mine!

 

I take the monthly increase in the RHI reading, say 24,000 kw, and use a benchmark of 4500kw per tonne of seasoned wood, which as I recall, I got from the forestry commission or similar info? So that equates to 5.34 tonnes of wood consumed.
