Kromschroder Set of nozzle BR_L Rp 3/8 74923481

This is a set of air nozzles for industrial burners manufactured by Kromschroder. The set is designed for precise air metering in burner systems, ensuring the correct gas/air ratio for stable combustion. Each nozzle has an orifice diameter of 3.3 mm and a Rp 3/8 thread. The nozzles are intended for use with air and fit Kromschroder industrial burners. The SKU is 74923481.

For this type of gas nozzle, replacement is selected by matching the thread size and orifice diameter to the burner's original specification. The nozzle is typically mounted on the burner's mixing tube or gas train downstream of the gas valve. Before ordering, measure the thread and the orifice diameter of the old nozzle, and confirm the gas family and burner rated capacity are compatible. During installation, inspect the seating surface and threads for damage, and use a thread sealant compatible with gas. Avoid overtightening, which can distort the orifice.

Typical failure modes include blockage or partial blockage of the orifice by debris, which changes the effective orifice size and disrupts the gas/air mixture. This can result in incomplete combustion, flame instability, or burner lockout. Also, using a nozzle with the wrong orifice size or thread will cause similar problems. Check the nozzle for cleanliness, damage, and correct size against the burner specification.
