Blog »  Sweden new RT1600 retort delivered

Continuing our export drive a new Charcoal Retort RT1600 was built and delivered to Sweden last week and I (Nick Harris) went over to commission it with help from the new owner 'Hans'
This is the second retort to be built, installed and commissioned for the Swedish client who owns 4000 acres of rich woodland estate in Swedish. Nordic pine and glass birch grow very slowly on this sandy bed where trees find the nutrients are hard to find (taking 50yrs of growth to produce 8 inch diameter). Hence trees grow extremely slowly and are more dense than the those grown in the UK.

During commissioning of the charcoal retort the 1st burn when very well lasting 15 hours and producing great new lumpwood charcoal of about 550 - 600Kgs.
The feedstock they were using was Glass Birch.  Because of this density of wood it produces lots of gases with continuous retorting.
The 2nd burn was more even with Hans in control keeping the retort to 525-550 degrees of 10 hrs which was a more controlling temperature producing the same kilos as the first.

Another charcoal retort successfully installed and working!
