Which component does not affect the fuel to the boiler when the water level drops?

Water level monitor
Low-water cut-off device
Steam trap
Burner control

The correct answer is: Low-water cut-off device

The low-water cut-off device plays a critical role in boiler operation by preventing the boiler from operating under unsafe low water conditions. When the water level drops to a certain point, this device activates an automatic shut-off of the fuel supply to the burner, thereby protecting the boiler from damage caused by dry firing. In contrast, the fuel to the boiler is influenced by several other components. The water level monitor alerts operators to changes in water levels, while steam traps manage the release of condensate and prevent steam loss, indirectly affecting the overall system. Furthermore, the burner control is responsible for regulating the fuel supply based on the operational demands of the system. Thus, the low-water cut-off device is uniquely designed to respond specifically to low water levels, making it the only component here that directly stops the fuel flow when the water level drops, rather than maintaining or adjusting fuel supply under those conditions.
