dc.description.abstract
The advanced dual fluidized bed (DFB) steam gasification technology allows to generate medium-
calorific product gas from various feedstock. Thereby, biogenic residues, municipal and industrial
wastes e.g. sewage sludge or rejects from pulp and paper industry can be utilized. The varying fuel
properties of these feedstocks pose a challenge not only to the DFB reactor system, but also demand
improved gas cleaning of the generated product gas. The product gas can be used in a variety of synthesis
processes like Fischer-Tropsch (FT) or methanation or conditioning processes like hydrogen production.
This flexibility provides a promising use of biogenic feedstocks for the production of sustainable energy
carriers.
Over the last years, extensive research has been conducted and over 50 feedstocks were tested using a
100 kWth advanced DFB pilot plant at TU Wien. Based on the gained experience, a 1 MWth
demonstration plant was designed, built and commissioned during the last two years. Investigating the
feasibility of upscaling the advanced gasification technology with regards to product gas quality and
operation performance is the focus of the current experimental campaigns. In order to validate and verify
the data from these campaigns, a process flow simulation using the software IPSEpro is conducted to
calculate mass and energy balances. This paper presents the results from these simulations and
accompanying analytics to provide a comparison of different operating points for the feedstocks wood
chips, forest residues, bark and plastic rejects. Different temperatures, fuel loads, steam-to-fuel ratios
and circulation rates, determine these operating points.
Input data for the simulation model consists of records from the plants distributed control system,
feedstock and bed material analyses, online gas analytics, and analytical results of tar, dust, H2O, NH3,
H2S, HCl, HF and HBr sampling. Key performance indicators for the demonstration plant include e.g.
cold gas efficiency, water conversion, and product gas yield. Additionally, by the use of the simulation
results, the fluidization regimes in the reactor system can be determined.
In order to investigate long-term operation, scale-up considerations, minimizing the risk of technology
development and finally create the basis for techno-economic evaluation of this technology in an
industrial environment according to TRL 5, an upscale to a 1 MWth fuel input power demonstration plant
was performed. Results from the simulation allow drawing meaningful comparisons between design
parameters, derived from 100 kWth pilot plant operation and the up-scaled 1 MWth demonstration plant.
This gives the opportunity to generate design values for industrial applications of advanced DFB
gasification in the future. The results enable a contribution to sustainability and energy security.
