Burning rape straw compared to wood

[quattro]

When the juice bottle is called upon things can't be going well!

We managed about 150 round bales this season which I will soon find in the straw shed, will see how they are the. But the test bales burnt seemed fine.

It hasn't occurred to me that hestons may be harder to bale up as strings not nets? Bugger.

Hesstons bale osr straw easily

 

[Cowcalf]

Torrefied pellets about £250/tonne

at what price is oil equivalent to this ?

Need one of these bad boys from oz. baler fed by conveyor out of combine.

I wonder how that'sowered, surely not PTO?

Good, what sort of tonnage do you get per acre? What weight would a Heston be, I am guessing about 4-500 kg?

Depends on crop but2/3 bales
Weight wise depending on age of baler 450/550kgs

Thanks. That's what I has allowed for, reassuring.

Heating oil @ 36ppl = 3.6p/kWh
Torrefied pellets @£250/t = 3.6p/kWh

Rape straw the best but with wood its the latent heat that carries on and lasts heat longer.

I had the same problem with them not understanding,drove me nuts. They said our purpose built grain stores were not wholly enclosed as they had vents in roof apex! Had to explain that we dry with the doors open to let the danp air out!

Did you get it through with no doors ?

I know a boiler fed by osr straw and they are only getting 2000kwh per tonne. Burns well with hardly any ash but wheat straw gives a lot more heat.

What kWh would you get with wheat straw ?

 

[Still Farming]

Depends on moisture content .

 

[Turra farmer]

Depends on moisture content .

The same moisture content as the rape straw you mentioned

 

[Still Farming]

A 4ft round bale should get 150-200 kwths ?

I agree with cow calf on this but still plan on burning it, have heard that to though.

How much heat does 400 kg of wood give, assume it's at 35%?

Linseed is the best I have found, burnt 5 round bales in 25 hrs this week, approx 4500 kW from it.

400kg of wood a day what are you heating

 

[Still Farming]

Unless you grow wood on farm to buy it is expensive .
I know compared to coal -oil or gas its cheaper but even sourced cheap to cut into logs or diesel to chip to then burn costs money .
Round bales straw bought are around £6- £12 each or if you grow your own corn just baling costs so lot to look at?

 

[Doing it for the kids]

Burnt about 800 rounds of OSR in the last few months.

Averaging 4 - 550 kWh per bale between boiler and tank. Boiler about 78% efficient, bales about 190 kg

I hate wheat straw, never burns well, or hot and leaves lots of ash. Fortunately don't need it though and having just sold some at £50 / t it's just as well!

Depends on quality etc but we've burnt about 900 tonnes so far and are averaging 3400kwh/tonne. We are using Heston bales and get a bad one slip through that's not just wet but also compacted and it's a problem. Likewise bales that are very dry such as 8% they burn to quickly. Around 15% moisture and a year old barn stored straw is the best.

For some reason spring wheat straw isn't so good as winter wheat straw also.

 

[Doing it for the kids]

A round bale costs me £2.80 last year, 2 days labour cleared the lot.

Earns me about £48 a bale ignoring cost of bale storage, labour and loss of nutrients to soil

Today's returns will be less because the RHI isn't paying out 9p /kWh but in the right settting it's still good

Looks like New Holland thought Challenger was a yellow Claas overseas?!
