Latest Patents
Douglas holds a patent for a "Nozzle for use in a burner." This nozzle is specifically designed for high excess air burners. It features three combustion chambers and an outer flame retention ring, which supports the combustion of gaseous fuel across a range of volumetric flow rates. The design allows for staged combustion air to be directed to each combustion chamber and the outer flame retention ring. This mixing of fuel and air creates a combustible fuel-air mixture. The combustion process begins in the first chamber at lower fuel flow rates and transitions to the second and third chambers as fuel flow increases. The second combustion chamber is uniquely designed with a radially inwardly converging sidewall, facilitating a smooth transition of the flame.
