🔍 Key Concepts

• Boiler combustion control and the relationship between air, fuel, and feedwater • Purpose of forced draft air in maintaining safe combustion • Effect of increasing firing rate on steam pressure and water level

💭 Think About

• When you want more steam production (higher firing rate), which variable must be adjusted so combustion stays safe and complete before you add more heat? • What happens if you increase fuel flow without first making sure there is enough air available in the furnace? • As firing rate goes up, which parameter (air, fuel, feedwater, or steam pressure) must lead, which must follow, and which one is the result rather than a control action?

✅ Before You Answer

• Think about proper air‑fuel ratio and which control change protects against smoke, soot, and possible furnace explosions. • Consider which action is normally handled by combustion control systems as the initiating change when demand for steam increases. • Distinguish between a variable you actively change (control) and a variable like steam pressure, which usually changes in response to increased firing.
