🔍 Key Concepts

• Proper maintenance procedures for burner atomizers on auxiliary boilers • Safe methods for removing or softening hard carbon deposits from fuel equipment • Compatibility and risks of using steam, water, acids, or fuel oils on precision burner components

💭 Think About

• Think about which substance can penetrate and loosen baked-on carbon without damaging finely machined metal surfaces or altering clearances. • Consider which options might introduce corrosion, pitting, or distortion in alloy steel parts used in burner tips and nozzles. • Ask yourself which methods are actually used in routine shipboard practice versus those more suited to scale removal or general cleaning.

✅ Before You Answer

• Eliminate any option that could corrode or chemically attack steel or brass components in the atomizer. • Question whether using live steam directly on small precision parts is standard practice for carbon removal, or more for line blowing and heating. • Consider which liquid is both a common fuel or solvent on board and known to safely soak and loosen carbon on fuel system components.
