摘要
"UNIT TO INJECT A MAIN GAS INSIDE AN OVEN COMBUSTION ZONE AND PROCESSES TO INJECT GAS INSIDE AN OVEN ZONE AND TO BURN FUEL AND OXIDANT IN THE COMBUSTION ZONE". A system and process for protecting a nozzle that injects a high-speed main gas into an oven or combustion zone. The nozzle is located in a lowered passage in the opening of the passage exit door that communicates with the combustion zone. Purge gas is inserted into the passage upstream of the nozzle. The volume of purge gas is greater than 50% of the total volume of main gas and purge gas and the purge gas has a velocity of at least 3.048 m / s, thus preventing oven gases from entering the passage and attacking the nozzle.
