Biomass boiler for drying timber?

[ash_smith123]

Yup it does what it should do. I have got a 10,000 litre accumulator heated by the dragon and then fed to the kiln. 4 x 650watt fans/heat exchangers. Depends if you are into RHI? The RHI way outstrips the cost of electrics etc.

 

Been running it for a month and it dries a load of split/processed logs down to 11 - 18% depending where it was in the kiln in about 6-7 days. Up by the fans is the lower end. We are looking at how we can load the kiln better and maybe circulate the stock so that we have a continuous load of wood coming ready instead of a complete kiln every seven days. Early days for us but it works fine.

 

Where are you based you can come and have a look if you like?

 

Or have a look at my website there are some pictures on there?

 

Tell Phil I told you about it.....I told him he needed me to sell them for him!! LOL

 

 

Are you on RHI with your system or not?

Boiler heats its water jacket which is then circulated to the accumulation then pumped to heat exchangers in the kiln and then returns to accumulator. Mine has pressure vessels to maintain the system pressure and to stop the water boiling in the system. If you don't have an accumulator the boiler feeds directly to the heat exchangers but as soon as the boiler needs more fuel or goes out the temp in the kiln will drop. The accumulator allliws the kiln to run 24/7 almost. Valves and meters are so involved fir RHI

Application waiting final approval at mo from Ofgem. I had it preaccredited in March and it has finished in the technical areas, just providing photos of meters and readings to finish off and be approved.

 

Also had the arb arisings from which we fuel the boiler and provide the source of the logs for retail approved on BSL as virgin seasoned and virgin foce dried so we can self supply our own fuel as well as having an approved log for other RHI boilers (which will be required after Nov 15).
