Boiler fuel oil atomizer parts should be cleaned by soaking in 'tip cleaner' or diesel fuel and __________.

🔍 Key Concepts

• Fuel oil atomizer operation and why correct spray pattern depends on precise clearances and smooth surfaces • Effects of abrasive cleaning methods on finely machined metal parts and orifices • Good engineering practice for cleaning precision fuel system components

💭 Think About

• Which choices involve any kind of abrasion or removal of metal from the atomizer surfaces or orifices? • For a small precision hole in an atomizer tip, what kind of damage (even if very slight) would most affect spray pattern and combustion? • Among the options, which method is most consistent with "non-damaging, gentle cleaning" after soaking?

✅ Before You Answer

• Identify which tools/materials are abrasive (will scratch, wear, or enlarge orifices). • Consider manufacturer advice for precision injection/atomizing components: do they allow scraping or polishing with metal tools or abrasives? • Ask: Would this method risk changing the size or shape of the spray hole or sealing surfaces, even a little? If yes, rule it out.
