General
2.2 Recommended nozzles and pressures
Because of the different types of boiler in existence, with varying furnace
geometries and furnace loads, it is not possible to commit to any given spray
angle or spay pattern. Note that spray angles and spray patterns change
with pump pressures.

.
2.3.1 Burner with preheater
Allow for a reduction in oil quantity of 5–20% with preheating owing to:
• Temperature increases at the nozzle.
• Nozzle design.
• Capacity (the higher the capacity the lower the difference).
