Abstract:
The provision of renewable energy to sectors with significant emission challenges is a critical component of the transition to green technologies. Industries requiring high-temperature heat are a constituent of this sector. The utilization of waste wood as a fuel source not only addresses the need for renewable energy but also aligns with the concept of cascading use. The present study examined a waste wood gasification setup with downstream gas treatment and a novel 150 kW lean gas burner test rig. The aim was to address critical issues for the industrial realization, such as low heating value, high tar content, high NOx emissions, and flame stability under different operation conditions. Utilizing a MEA or water scrubber resulted in a 16 % increase in the LHV of the producer gas, accompanied by a reduction in tar compounds by over 40 % and ammonia by up to 89 %. This led to a substantial reduction in NOx emissions in the exhaust gas, reaching 67 %. An even higher decrease of up to 88 % in NOx emissions was attained by optimizing the specially developed lean gas burner system. Employing primary air swirling and secondary air staging in the burner test set up simultaneously improved flame stability.
