Can I use charcoal or coal in lieu of wood in an Air Burners system to support combustion?
Yes, the system will function well with coal; coal may cause some additional smoke (emissions), and wood waste will be needed to start the fire. You will need to check with your local authorities to insure the use of coal is legal. Coal has been used in the US and in England by MAFF (now DEFRA) to support combustion for the disposal diseased animal carcasses where a supply wood waste was scarce.
