We are offering coal briquettes packaged in jumbo sacks of 1000 kg, and sacks of 10 and 25 kg, but we also offer delivery of loose briquettes by lorries or train carriages. Coal briquettes can be used in all closed-in fire-box systems fed by coal. The advantage of coal briquettes is that the feeding intervals are very long, and the quantity of briquette used for one feeding is more than 60% smaller when compared to coal. Combining of selected coal and connective material of bio origin gives to BRIGO briquette ability to oxidize quickly and emit warmth for a long time. Due to the manner of combustion and additions to the briquette, the emission of CO2 has been reduced, as well as emission of combustible sulfur, that is, BRIGO briquette meets all European standardsprescribed for this energy source. The remnants after combustion are loose and small.
