Metodología para el Desarrollo de Sistemas de Combustión Sin Llama

A methodology to design flameless combustion heating equipment is presented. The design of flameless combustion devices requires an appropriate methodology to guarantee the necessary conditions to obtain this combustion mode. Nevertheless, such methodologies are not available in the scientific literature. For this, a combination of dynamic scaling, based on air/gas impulse ratio, and numerical simulation with FLUENT® has been employed to get suitable geometric configurations and dimensions for discharging fuel and comburent air. The proposed methodology has been applied to the design of a 20 kW experimental furnace using natural gas as fuel. The validity of the methodology has been verified with stable flameless combustion operation in the furnace.
