Abstract
The improved fuel-air mixer tube is devoid of secondary air ports and includes a passage for flowing gaseous fuel to a burner and a restrictor accelerating such gaseous fuel through a region of maximum gas velocity. An air entry port is in flow communication with such region for supplying primary air required to form a combustible mixture. The tube is thereby naturally aspirated and gaseous fuel and air are turbulently mixed to form a substantially homogeneous mixture.
