Question 1 of 27070

Q

A practical consideration to allow for when operating a boiler at low load with regard to heat absorption is the requirement to __________.

🔍 Key Concepts

• boiler operation at low load and how heat transfer surfaces are affected • formation of condensate and corrosion in exhaust gas passages • effects of incomplete combustion vs. moisture/acid formation in flue gases

💭 Think About

• When the boiler is firing at low load, what happens to the temperature of the gases leaving the boiler and how can that affect metal surfaces? • Which choice relates directly to preventing condensation and acid attack in the uptake or economizer, rather than combustion chemistry alone? • Think about what practical operators actually monitor in the exhaust/uptake when they reduce load on a main or auxiliary boiler.

✅ Before You Answer

• Identify which option deals with dew point or condensation on cooler metal surfaces • Separate options about combustion products (CO, excess air) from those about protecting boiler structure from low-temperature corrosion • Ask: Which condition, if not controlled, would most likely lead to acidic moisture forming on cold uptake/economizer surfaces at low loads?
