MULTI-TORCH INJECTION BURNER Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: injection burner is used for burning of gaseous fuel in household boilers, apparatus and other units. Burner has tubular nozzle coupled to gas line through gas distributor, temperature controller and gas valve. Nozzle is provided with slotted holes, width of which is below critical size (1.6 mm for natural gas). Slotted holes are staggered across tubular nozzle axis and at angle to one another. This improves access of secondary air to base of flame-jet torch, and reduces torch length and ejection of harmful substances into atmosphere. EFFECT: enhanced efficiency of fuel burning. 3 cl, 6 dwg
