🔍 Key Concepts

• combustion process in a marine boiler (fuel + oxygen + heat) • excess air vs. the minimum (stoichiometric) air needed • effects of too little air and too much air on boiler efficiency

💭 Think About

• Ask yourself: What is the primary reason engineers add MORE air than the exact chemical requirement for burning fuel? • Consider which options describe a purpose of supplying excess air, and which describe side effects or separate issues in boiler operation. • Think about what happens inside the furnace if there is not quite enough air mixed with the fuel. What visible signs or byproducts might you see?

✅ Before You Answer

• Verify which choice is directly related to ensuring proper burning of fuel in the furnace. • Check whether fluctuations in steam demand are controlled mainly by air supply or by fuel firing rate and boiler controls. • Consider whether heat losses up the stack are something engineers try to cause with excess air or something they try to minimize.
