🔍 Key Concepts

• Automatic combustion control in boilers responds to steam pressure changes • Relationship between steam demand, firing rate, fuel and air flow • Difference between controlling number of burners, register position, and fuel/air valves

💭 Think About

• If steam pressure is dropping at constant design load, what does that tell you about steam demand versus current firing rate? • In a modulating combustion control system, which components typically move together to increase heat input: individual burners, air registers alone, or a linked fuel-and-air system? • Which option describes a normal automatic response to a gradual pressure change, rather than a step change like starting extra burners?

✅ Before You Answer

• Verify how modulating combustion controls usually increase firing rate (think fuel AND air together). • Consider which choice best maintains proper fuel/air ratio while increasing heat input. • Eliminate any option that only adjusts steam flow without directly changing heat input from the burner.
