Short Description
The two-bed fluidized bed steam gas generator is meant to be a demonstration plant for the production of synthesis gas from solid fuels.
The plant consists of a gas generation reactor based on the technology of the 100kW two-bed fluidized bed steam gasifier at the Vienna University of Technology and, with a fuel input of 1 MW (thermal), represents a further step towards an industrial plant. Further components of the plant are a cooling and dedusting system on the exhaust gas side and a coarse gas cleaning system on the synthesis gas side. The coarse gas cleaning system consists of a hot gas filter and a gas scrubber, which prepares the synthesis gas for further processes. The system also has an afterburner chamber which burns the unused synthesis gas. This design makes it possible to maintain continuous operation for several weeks. The demonstration plant enables the use of a wide range of fuels, from high-quality wood chips to residual materials (e.g. plastic fractions from waste, wood residues/bark, sewage sludge).
The system has a large number of measuring points. In addition to pressure and temperature profiles, the gas composition (both waste gas and synthesis gas) can also be measured online. In addition, there are several sampling options for measuring other process parameters (e.g. gas moisture, tar content, inorganic components in the gas).
