Technical data
Disc and plate atomizers are used where the required fuel output is far beyond what a single pressure nozzle can pass: 100 to 5000 kg/h. Where the flow rate is too high for a single bore, several discs are stacked and the flow is distributed across them.
Spray angle and spray pattern are matched to the individual burner head, and the atomizer can be supplied with or without a shut-off needle. The turn-down ratio reaches 1:3 – 1:6.
Technical data
- Flow rate: 100 – 5000 kg/h
- Turndown: 1:3 – 1:6
- Spray angle: 30° – 80°
- Shut-off needle: Available with and without shut-off needle
- Spray pattern: Matching the individual burner head
All figures are nominal reference values at 5 cSt fuel viscosity. Final dimensions are fixed together with the burner head and are confirmed on the order drawing.
Applications
Fields of application
- Large industrial oil burners and furnaces
- Asphalt plants and process heaters with very high fuel output
- Burners that need the spray angle matched to an existing flame tube
Datasheets, drawings, output curves and manuals for this series are published in the documentation library.
Fluid Control Instruments Ltd manufactures to order and quotes per project: send burner head drawings, fuel specification and required flow range to receive a binding quotation.

Frequently asked questions
Which flow rate range does this series cover?
The published range is 100 – 5000 kg/h. Because the atomizer is machined per order, intermediate values inside the range are available as well; send the required output at full load and at minimum load with the burner head drawing.
How large is the turn-down ratio, and how is it achieved?
The turn-down ratio is 1:3 – 1:6. The atomizer is dimensioned for the burner head, and the return-flow (spill-back) or atomizing-medium control keeps the spray pattern stable across the whole modulation band.
Do we need a shut-off needle, and what does it change?
This series is available without. A shut-off needle closes the nozzle orifice when the burner stops, so no fuel drips into the combustion chamber after shutdown; without it the burner head must provide the sealing function.
Which fuels can be atomized?
Light and heavy fuel oil are the standard duty, including used oil and vegetable oils where viscosity and contamination stay inside the agreed window. The internal geometry is chosen so that the flow rate depends as little as possible on oil temperature; always state density, viscosity and operating temperature when requesting a quotation.
What is the lead time and the minimum order quantity?
Atomizers are made to order; a typical lead time is about 42 days after drawing approval, and the minimum order quantity is 1 piece. Consumable items such as orifices, swirlers, discs and needles are normally available from stock.
Can this series replace the atomizer that is installed today?
Yes in most cases. Send the old order number, a photo of the burner head and the required output; we compare the spray angle, the pattern and the interface with the original Fluid Control Instruments Ltd drawing and confirm which type is interchangeable before the order is placed.
