Thanks for posting, do you know (roughly) how many kWh per load/tonne/cube?

I have a confession, I saw a thread entitled Climbing Wellies and immediately though that a footware revolution had occurred in some way, eagerly expecting some exciting news on a new product, I was somewhat disappointed to find that apparently people climb Sequoya for fun

You, Sir obviously do not keep cattle. Wet Concrete, work of the Devil, wrecks Wellies:biggrin:

Broonies was over 100C as well, I hadnt imagined anyone doing it that hot, although its obviously going to be miles quicker. However it rather takes it out of the realms of an add on to a Log Gassifying boiler with a domestic heritage. Im off for a recalculate !

vat & bag?

:biggrin:I was hoping for any old answer just to calculate from. There must be a temperature around which losses increase and productivity decreases. I havent found Broonies post yet!

What Ive come up with so far.... Home build heat exchanger, 1 sheet 1.2 by 2.4 Aluminium sheet 2mm thick, sandwiched in between two sheets of ply, but spaced off to give a 30mm air gap either side. Mounted vertically. Outward air travelling downwards, condenses moisture on the Ally sheet dripping off at the bottom, inward air rises up gaining temperature and if reintroduced near the fan inlet would probably not require its own fan. Assuming the kiln is running at 40 C, 10 degree differential across the sides will give 2.5 kw of saved heat, in theory this would be equivalent to running 1 kg of water out and a bit of air cooling every 20 minutes. Apart from the 50 quid for parts, this is 2.5 kwh every hour the kiln is running,for free no moving parts . Saving at 3 p per kWh 7.5 pence per hour It would be interesting to know how much water a dehumidifier would extract per kWh of leccie, More energy is retained as the water is vented out cold, but even though the enegy is not lost it is costing 11 p or so buy electric instead of being provided by cheap wood ( and accruing RHI entitlement (and being sustainable)) I must get back to work!!

Can anyone enlighten me about the optimum operating temp in log drying kilns please

I have seen shards like yours from a Heizo when the cordwood went in sideways the teeth just chew great lumps off instead of making decent chips, having decent length material and keeping the lengths going in straight makes an amazing difference

what temperature are you running the kiln at? (roughly)

I dont think it would be very far off whats going through my boiler at the moment, but in the bottom left picture you can see a fair few shards, which tend to travel along the auger , but pop out just before it goes through the wall into the boiler house forming a sort of birds nest at that point. Im sure that if I didnt clear it out before refilling, then eventually it would stop.

there is a product for the domestic ventilation market which transfers the heat from outgoing air to fresh incoming air, dont know if they are any good though.

very much depends where you are

Dont you need to lay the log down to noodle? If you want really long noodles have the nose lower

definitely spend some time/money on a bag frame/hopper what size potato boxes? and what size bags?

how many boxes have you got to do?

they seem to be made by BF Goodrich, if they are as awesome as the tyres then we should all have some "and no backside access required"!!

thats a Uman Bean Tree

I bough one with my new brushcutter, but the hole was the wrong size, (cant remeber the model atm) sorry not to answer your original question

then out with the trusty bowsaw:001_rolleyes:

for clarity a 2.5kW panel would generate 4.88 kWh per day

Lewis, do you have any guidance about the chainsaw oil issue?

possibly should have bought her the iphone6, more hot air and probably for fewer pennies (dont tell anyone i said that)

but does hers have a remote control????
