🔍 Key Concepts

• Heat balance in an incinerator (waste/sludge + auxiliary fuel + combustion air) • Difference between controlling temperature by changing heat input vs. diluting or bypassing gases • Purpose of exhaust temperature control for protecting equipment and ensuring complete combustion

💭 Think About

• Which method directly changes how much heat is being RELEASED in the combustion chamber, instead of just moving or diluting the hot gases? • If you suddenly have low‑calorific (low heat value) sludge, which control method would most effectively keep the exhaust temperature high enough for good combustion? • Which option would an automatic temperature controller most logically modulate to maintain a set exhaust temperature under varying waste loads?

✅ Before You Answer

• Identify which choice affects the rate of heat release (energy input) rather than just gas flow path or dilution. • Consider which option is typically tied to a temperature controller on marine incinerator systems. • Eliminate options that only cool or reroute gases without truly stabilizing combustion temperature.
