Jan 01, 2008 · Fixed bed biomass gasification is a promising technology to produce heat and power from a renewable energy source. A twin-fire fixed bed gasifier based CHP plant was realized in the year 2003 in Wr. Neustadt, Austria. Wood chips are used as fuel, which are dried and sieved before being gasified to a low calorific gas of about 5.8 MJ/Nm 3 dry.
Gasifiers are classified into two main categories, namely fixed bed gasifiers and fluidized bed gasifiers. Their designs are mainly based on certain parameters like gasification chemistry, gasifying media, equivalence ratio, steam-to-biomass ratio, gasifier temperature, and pressure. These parameters are also responsible for product yields. Further, fixed bed gasifiers are broadly classified
1/5/2012 · The modeling of biomass gasification processes by simulators such as Aspen Plus is a powerful tool to assess mass and energy balances and to optimize process designs. A detailed model of the gasification reactor is one of the key points to achieve an accurate process description. A model for biomass gasification in dual fluidized bed (DFB) reactors by coupling Aspen Plus and dedicated Fortran
Here is shown a fixed bed gasifier, based on the combustion or gasification of solid fuel, and featuring a comparatively simple structure and low equipment cost. Fig. 4.2.2 shows a concept diagram of the gasifier. Wood chips of about 2.5-5 cm are generally used as the raw material.
