Kromschroder Set of nozzle BR_L Rp 1/4 74923480

This gas nozzle set is intended for natural gas service and has an orifice diameter of 0.94 mm. The connection is a female Rp 1/4 thread. It is used in Kromschroder pilot burners, ignition devices, small industrial burners, and boilers. The set provides calibrated gas metering to maintain a stable flame.

Nozzles of this type are selected by matching the thread size and the orifice diameter to the burner's injector holder and heat output. The thread must be identical (for instance Rp 1/4), and the orifice diameter must correspond exactly to the specified gas type and burner capacity. Before ordering, measure the thread and verify the orifice diameter and gas type. During installation, confirm that the nozzle is clean and undamaged, and do not reuse a part with a worn, corroded, or deformed orifice edge.

When a nozzle of this kind is mismatched or worn, the burner may show unstable ignition, yellow or uneven flame, or sooting. A deformed or corroded orifice changes gas flow, leading to poor combustion and increased fuel consumption. Check the orifice diameter and the condition of the nozzle edge; replace the nozzle if the opening is damaged or blocked.
