4PLUS briquettes

4plus briketes

Calorific value and burning time of wood-chip briquettes correlates with humidity and density of the briquettes: the drier and denser briquettes, the longer they burn and more heat produce.


While briquettes burn, water evaporates and cracks appear, which leads to imminent crumbling.


The drier the briquette, the longer it burns and less succumb to crumbling.


4PLUS aspen briquettes are significantly denser and dryer than other ones on the market.


Their combustion temperature is higher, while the burning and disintegration time is longer.
