These heaters use a great deal of wet woodchips. The quality fluctuates greatly with the seasons, making the efficiency drop. The poor combustion increases the emissions greatly and you are left with incompletely incinerated ash residue. If you cofire torrefied chips, they operate more stably, cleaner and with higher efficiency.'

Bituminous. The next stage of coal is hard and a shiny, smooth black color, with a high Btu rating. It also contains a sticky substance known as bitumen, which is used when making asphalt, but this sticky coal makes it tricky to undergo coal drying processes before being burned. Much of this coal is used for energy production as it does not ...
