Abstract:
In 2016 a counter-cu urrent fixed-bed biomass gasification plant in laboratory sc cale has been set up. This batch gasifier operates at temperaturresup to 950 °C and pressures up to 20 bar.Different gasific cation agents (mixtures of N2, O2, air, steam, and CO2) as well l as different feedstocks, e.g. chips and pellets with a particl le diameter between 3 and 20 mm, can be used. For a deeper uunderstanding of the gasification reaction, 20 thermocouplees are installed inside the gasification reactor to visualize the temperature profile of the fixed bed. Furthermore, a gravim metric analysis system for the fixed-bed mass during the reac ction and three gas sampling points extending along the fixed-bed height for gas analysis at 450 °C are installed. Also o conclusions on coke and slag building inside the gasificatio on reactor can be drawn. First test results ofcurrently running projects with this gasification plant are expected in third to fourth quarter of 2016.
