Abstract

Gasification of biomass can be a very effective technology to fight climate change due to the carbon negativity of the process. However, syngas combustion could release a variety of pollutant compounds such as carbon monoxide and nitrogen dioxide. Improving the emissions of syngas combustion is very important in order to promote the diffusion of small scale gasifiers that often have no complex flue gas treatment systems. In this work a study on syngas combustion from a small scale gasification system is presented. A combustion chamber designed after a preliminary numerical evaluation was built to test different geometrical configurations. Two metal plates were used to modify the combustion chamber geometry in order to test different flare shapes. An experimental campaign with an emission analyzer was carried out to identify the best combustion chamber shape and to evaluate the pollutant released by syngas combustion. To further explore syngas combustion, the flammability limits were evaluated through the “Le Chatelier” equation and considering the presence of various inert gases.
