🔍 Key Concepts

• Burner sprayer plate code markings and what each part usually represents • Difference between orifice size, drill size, and tip size in fuel burners • Relationship between numbers in a code and units like square inches or psi

💭 Think About

• Ask yourself: does this kind of small burner orifice usually get measured directly in square inches, or is it more often related to drill or tip sizing? • Think about whether fuel pressure (psi) is normally stamped on the sprayer plate itself, or if that information is usually found somewhere else. • Consider whether code numbers on small parts often represent exact measurements (like 0.32 in²) or reference sizes (like drill or tip numbers).

✅ Before You Answer

• Check if a tiny orifice on a burner plate realistically has an area as large as 0.32 square inch. • Consider where you would normally find a pressure rating (psi) for a burner — on the plate, the pump, or in the manual. • Ask whether manufacturers more commonly stamp drill sizes / tip sizes or exact physical areas on small burner components.
