Is anyone burning miscanthus ?
I'm wondering if its possible to chop it direct with a maize header blow air through it to dry it a bit then feed it into the boiler either blended with chip or batch burning on its own.

We used to chop about 10 acres for a customer. Piled in a shed and fed into his boiler to heat his house. Can't remember any drying setup but I'm sure he must have had something.

I think miscanthus has a very good long term future if I could buy some cheap land that was suited for cropping I would put it into miscanthus. but to me there is only 1 way to use this and that is in pellet form, it has 1 major problem is that is clinkers , so lime is added in the pellets to stop that from happening.There are also people working on genetics of the plant to try and stop this from happening.I am presently growing some plants at home ,they are doing well keep rabbits and vermin off they will destroy it.

Derek, that is why you should only burn miscanthus in boilers with a water cooled moving grate equipped with furnace temperature controller. Moving grate allows for efficient de-ashing, and helps to scrape any slag. Keeping temperature below 700C helps to stop slagging from occuring, as this is below Silica compounds melting point.
If you are interested in finding out more let me know.

So did you swath it then forage it or forage direct? Then did he literally tip it up into a pile? and would you know what boiler he used or how he fed it into the boiler at all? pm me if you want. Thanks.

Cut it direct with a maize head and piled it in his shed. I'm guessing he used pedestals similar to a grain store to stop it heating but can't be sure.
He showed me his boiler but I'm afraid I don't remember the brand or any details. He was a plumber and specialised in installing these type systems so knew his stuff

Any one still doing/ going into this or know much about it? With the arable job not looking so rosey just wondered about putting some of the wetter/ poorer land in with muscanthus if it's a viable thing to do

Would not recommend Miscanthus in wetter poorer land as you harvest it generally at the wettest time of year and on wet land it just makes a mess.

That is what I was advised a couple of years ago when I was speaking to a Grower. For me, it was the requirement of hard road access year round that stopped my interest..

If you want to grow and harvest biomass on wetter land, willow is better as after a couple of years, you have a good root system to support machinery, and after 8-10 years you will have a MASSIVE root system to support machinery!!
