North American Oil Atomizers Steam or Compressed Air Nozzle Mix
Bulletin 5627
5627 Atomizers break liquids into a fine mist for incineration using steam or compressed air. These liquids must be of a viscosity of 100 SSU or less. A 5627 Atomizer cans be used by itself or as an insert in a Fives North American or other manufacturer’s burner body. It frequently is used to atomize waste liquids. If a 5627 Atomizer is to be used in a burner body, appropriate length ("L" dimension) must be specified. When an atomizer is to "stand alone," adequate combustion air must be available, either in the combustion chamber or around the atomizer. The standard 60 degree spray included angle nozzle produces a long flame typically required for steel reheat furnaces, rotary dryers and kilns, and some melters. Optional mounting flange adapters are available for mounting with standard 450# ANSI bolt patterns. Special adapters can be designed to match existing burners or mountings. Contact your North American Sales Representative for further information. Construction and Operation: The stainless steel oil and steam nozzles are concentric and flush; therefore, one pressure dœs not affect the other, and a North American 7052 Ratiotrol TM can be used. Standard oil nozzle material is 304 SST. 316 SST and Hastelloy C-276 are also available as options for corrosive fluids.

A 5627 oil nozzle is readily accessible for cleaning if atomizer is piped as shown dotted on back of this sheet. Remove pipe plug to open a straight passage to nozzle, which then can be cleaned with steam or a piece of wire.
