Get a QuoteThe flue temperature plays an important role because an increase in the mean flue temperature (MFT) over a range between 1165 and 1390 °C –to produce carbonization rates of 20, 25, and 30 mm/h, respectively-, significantly modifies the yield, properties, and composition of the by-products. A higher amount of COG is generated with a lower calorific value, while the tar yield decreases.
