Investigation of air-blown biomass gasification in a pilot setup

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. The 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.
