Design and construction of gas-fed burners for laboratory studies of flame structure

The study of buoyant convection for diffusion flames in wildland fires is critical to understanding heating and cooling dynamics related to particle ignition. Studies based on solid biomass fuels are made difficult by short flame residence time associated with fine fuels. An alternative is to use artificial fuel gas rather than relying on pyrolysis of solid fuels to produce the gas products for combustion. This paper reports on the design, construction, and testing of gas-fed burners used for the study of flame characteristics.
