Moisture content of wood chip?

[renewablejohn]

Really considering a small drying floor using heat from the biomass to dry our own chip down further. (We’re self supplier woodsure certified etc.)

Have read up and unfortunately we’d need to have this heat ‘unmetered’ so that we aren’t claiming the RHI on it, due to the shenanigans of certain practices carried out in the early days.

But it still feels like a goer. I’ve heard from one person the ratio is about 1:7 for amount of fuel required to burn against amount of fuel you can dry. So 1m^3 produces the heat to dry 7m^3.

Thought would then be in the future post RHI you’d be able to take surgeons’ chip tipped then dried off and the only work required is a bit of shovelling. With a screener in there too.

Anyone doing something similar?

Easy way to lose customers trying to pass off tree surgeon woodchip as some sort of quality product ie G30 or G50. Would be acceptable in producton of wood pellets or briquettes but even that you have to be careful of the higher ash and clinker content due to the green waste and bark found in tree surgeon chip.

Arb chip doesn’t burn that well we find. Dried a fair bit down but not cost effective, it’s heat output is low, lots of ash and a fair bit of electric to dry it

Arb will work bout only in boilers with a great that moves and has adequate area and refractory volume, and decent controls etc
