🔍 Key Concepts

• Forced draft pressure and its effect on combustion rate and gas temperature • Relationship between firing rate, superheater outlet temperature, and stack temperature • Common causes of white smoke from the stack vs. black or grey smoke

💭 Think About

• For each choice, ask: If I reduce forced draft pressure (and thus air flow and firing intensity), would this logically tend to raise it, lower it, or have little effect? • Think about what condition usually produces white smoke specifically: is it more often related to too much heat, too little heat, excess water/steam, or fuel issues? • Consider whether high superheat temperature and high stack temperature usually move together when combustion intensity is reduced.

✅ Before You Answer

• Be clear that reducing forced draft pressure generally reduces combustion intensity and flue gas temperature. • Review what high superheat temperature and high stack temperature indicate about heat transfer and gas temperatures. • Verify what stack appearance (white vs black smoke) tells you about fuel-air ratio and water/steam in the exhaust.
