Fuel briquettes of "RUF" standard are obtained from 100% sawdust without artificial additives and without the addition of binders.
They are made by hydraulic pressing with a pressure of 300 atm.
They are distinguished by high density 950 - 1100 kg / m3, calorific value up to 4700 kcal / kg and ash content no more than 1%.
They look like a "brick" with the dimensions of the edges of 150 mm x 100 mm x 60 mm.
Packed in plastic wrap, 12 "RUF bricks" per pack.
The weight of one "RUF brick" is 840 - 900 g.
The duration of burning of RUF briquettes is due to their high density, which is ensured by the technology of hydraulic pressing itself, as well as by high-quality equipment on which RUF briquettes (roof) are produced.
In addition, the shape of the RUF briquette allows the briquette to be placed as tightly as possible in the furnace firebox.
The efficiency of using RUF briquette (roof) is due to the high density and low moisture content of 6-8%.
