Abstract
The paper presents results of experiments on low-temperature entrained-flow gasification of raw biomass with a broad fractional composition in a pilot setup under atmospheric pressure with a diverging duct and upflow. Here the fuel source is a wet pine-tree sawdust with the mean size 0.25 - 0.50 mm and the maximum size of 5 - 6 mm. The gasifier parameters: air flow rate is 8-15 m3/h, solid fuel rate is in the range 7.3-19.5 kg/h. Тhe produced syngas has the heating value is the range 2.47-5.58 MJ/m3 and this fits the technical requirements for fuel gases used in internal combustion engines and in gas turbine plants.
