Influence of the waste biomass gasification gas composition on the Laminar flame speed values

As a result of the gasification of the organic matter of biomass achieved a gas, which can be used in many ways. It can be burned in the engine, gas turbine or boiler, it can also be a substrate for the chemical processes. However, gas from gasification may, be characterised by high variability in composition depending on the process conditions and fuel composition before process. For this reason, its use may pose some difficulties. For example, it may be the design of burners and combustion chambers to ensure environmentally and energy efficient disposal. For this reason it is extremely important to know the basic properties of the gas. Laminar flame speed is a key parameter to be taken into account during designing equipment for the gas utilisation. The paper presents the results of experimental investigation of the laminar flame speed of the different kind of biomass gasification gases. Bunsen burner method was used. Additionally, the temperature distribution in the flame was determined. The results show that there are optimum conditions for conducting combustion of the biomass gasification gases, with which it is possible to carry out the stable process with effective heat release. The results indicate that low calorific gases from the thermal processing of biomass can be a source of fuel for the production of the final forms of energy.
