Technology Development and Conceptual Design of a Test Stand for the Optimization of a Gasification Process
Abstract:
In Germany around 8000 biogas plants have been installed previously. Around 180 of these plants feed the processed biogas into the grid. In the most of the plants the biogas is used in power generation (CHP). As a result, this large number of biogas plants produces a huge amount of fermentation residues along with the power generation. The 8000 biogas plants generate around 8.5 million metric tons of fermentation residues a year. Currently, the residues are primarily applied as organic fertilizer on soil nearby the biogas plants. In a special torrefaction process the fermentation residues are transformed to biochar in form of so-called Enertabs. The article introduces a gasification unit for Enertabs, which generates a low calorific gas. In addition the article gives a description of a conceptual test stand, in which the gasification unit is to be used with steam as a gasification medium and in which the unit generates the product gas under high pressure.
