What does a cube of dry logs weigh? Test

Thanks Lucan. I have a stacked to loose factor of 0.64. I've ordered the blue book and I'll find out their methodology.

 

Be aware its relevance to firewood logs is loose in that it deals with measurement of trees and the relation of volume to weight. Its purpose is to provide practical mesurement for sylviculture, the practice of growing trees for their timber.

 

Firewood logs are a luxury good not a primary energy source. Production of firewood logs requires a high labour input, each time a piece of wood is handled adds to this labour cost stacked firewood demands even more handling.

that's a very good point openspaceman, which is why a reliable means of converting loose to stacked (to kWh) is important. The only thing I'm worried about is that some suppliers may try to more loosely stack their loose loads, i.e give less logs per m3, should loose-m3 be the norm. What do you think? Especially if there is no regulation

I cannot imagine any way one could arrange logs in such a way they could occupy more space than when they are randomly dropped in from a processor.

 

As to regulation; I work in a sector that is heavilly regulated, the net result is the client whose system we work to has less choice of firms qualified to do the work because the entry level to the system is expensive and the jobs cost considerably more than in more normal environments.

 

When I worked with commercial biomass installations the designers fitted heat meters to the system, the plan was to pay for woodchip on the amount of hot water it would produce. No suppliers would supply on this basis bar one special case. It was a shame as there seemed to be a ripe opportunity to cut transport costs by electing to be paid on the meter.
