An air blower plays a crucial role in a boiler system by providing the air required for the combustion process. In a boiler, fuel needs to be ignited and burned efficiently to generate heat and produce steam. Combustion requires a consistent and adequate supply of air, specifically oxygen, which is facilitated by the air blower. By delivering this necessary air, the blower ensures that the combustion process occurs optimally, leading to efficient heat production and maintaining a stable operation of the boiler.

The other options address functions that are not relevant to the primary role of the air blower in the boiler system. Removing excess smoke emissions typically falls under the responsibility of emission control systems, while circulating steam is the function of pumps and piping. Likewise, controlling water levels in the boiler is managed by level sensors and feedwater systems. Each of these processes is critical to the overall functionality of the boiler but does not pertain to the air blower's direct responsibilities.
