kiln dryer

[K66 LOG]

hi their its a great set up just like mine. the reason why r5log has not gone for self feed boiler or my self is your not tied to burning one product ie? pallets ;wood waste. with chip or pellet boiler your tied

Ok, makes sense.

Impressive, no doubt about it.

Having multiple boilers like that reduces the headache of refueling in that if your refueling 24/7 the same man can refuel multiple boilers for effectively no extra cost.

Let's dry some wood!!

 

 

Jusus I thought our fuel bill was bad! [emoji23]

How many cubic metres are you burning a day?

[K66 LOG]

he will burning on about 90 to a 100 ton of wood per year , per boiler earning £ 20 ,000 trust me i know , because we do it ~ps r5log you will ,and the logs you sell from drying in the kiln are better then imports ,

[ash_smith123]

90-100 tons per boiler?

Because 100 ton would give you roughly 160-170 cubic metres. Are you saying you burn about 40 cubic metres per year per boiler and get £20k?

 

Just out of interest how long do you run the boilers for per day?

On the metre,how many kW per hour are you getting?

Batch boilers being about 50-60% efficient I'm guessing you will be getting about 80-100kw an hour?

How many tonnes of Softwood would you estimate Ash to secure the 20K RHI?

Hard to say as it depends what tarrif they are on.

But my guess is they burn 1.5/2 cubic metres in 10\12 hours. Duffryn would be best to say!

Probably about £100 in RHI a day per boiler.

200ish days to £20k (depending on tarrif) so 350/400 cubic metres per boiler would be my guess and that's a big guess because there's so many variables!

Yes D is a mine of Knowledge - he has posted before but I can't find the thread.

 

Others have posted their average m3 fuel burnt per batch

As Ashley said there are a number of variables here. The figures below are based on the Glen farrow boiler which is the only batch fed boiler I have a great deal of experience of. The comments are not a criticism of Glen Farrow my understanding is that most large batch fed boilers will deliver similar results.

 

If we take a 200kwh boiler, the rating relates to its peak output. Out of a 200kwh boiler you would realistically on expect to get 120kwh an hour maximum over the course of a day, probably less so let’s work on 100kwh.

Wood at 20% m/c has circa 4.2kwh per kg . Source Energy Cost Comparison | Nottingham Energy Partnership

 

So a tonne of wood at 20% m/c has 4,200kwh of energy in it

The boiler will only be 60% efficient. So out of the 4,200kwh you will only generate 2,520 kwh.

 

Working at 100kwh output from the boiler you will use a tonne of wood every 25 hours.

 

Based on the current medium tariff ( boilers over 200kwh) you would generate 5.18p per kwh. So every 25 hrs you would be paid £130 for a fuel cost of 1 tonne of fuel. I have used the medium tariff because most manufactures now offer a boiler just over 200kwh to ensure you get this.

 

The key to making the figures add up here is to use “free fuel” or getting paid to burn the fuel as I know one entrepreneurial user is doing.
