AIR Gasification 


Gasification is a process by which combustible materials are converted from a solid or liquid into a combustible gas using an "arrested combustion" process. By developing simple, yet effective manners of dealing with this conversion process, AIR Group has been able to effectively produce electricity from a wide variety of combustible materials such as tires, MSW/RDF, biomass, and dried sewage sludge. The substantial technical improvements that have evolved reduced footprint, allow for higher gas quality, simplified gas cooling and cleaning, high conversion efficiency, and with any true gasifier, not a source of air emissions, but a source of fuel gas for use. The gas produced which is clean, cool, primarily consisting of carbon monoxide, carbon dioxide, hydrogen, methane, nitrogen, and trace components derived from plastics, or other volatile sources. This gas is clean enough to operate a spark ignited internal combustion engine for power generation. Conversion efficiency is 80% with a 4-5% parasitic load, a simple system which allows for feeding of a wide range of materials easily. To produce 10 MW/h of electricity we need 250 tons of select MSW daily. To produce 2 MW/h of electricity we need 30 tons of plastics or tires daily


Biomass gasification is a complex thermo-chemical process involving numerous different reactions. The biomass gasification process can be divided into two parts: pyrolysis and gasification. Biomass gasification is a promising technology, which can contribute to develop future energy systems which are efficient and environmentally friendly in order to increase the share of renewable energy for heating, electricity, for energy production, the major concerns about syngas are its heating value, composition and possible contamination. The proportion of the combustible gas hydrogen (H2), methane (CH4), carbon monoxide (CO) and moisture determines the heating value of the gas. The composition of syngas depends on the biomass properties and gasifier operating conditions. For a specific gasification system, operating conditions play a vital role in all aspects of biomass gasification. These include carbon conversion, syngas composition, tars and soot formation and oxidation.
