The combustion control system is responsible for regulating the fuel-to-air ratio in a boiler. This system ensures that the correct amount of fuel is mixed with the appropriate amount of air to achieve efficient combustion. By maintaining the optimal ratio, the combustion control system helps to maximize energy output while minimizing emissions and the risk of incomplete combustion, which can lead to dangerous conditions such as carbon monoxide buildup.

The heat exchanger, on the other hand, is designed to transfer heat from the combustion process to the water or steam within the boiler system but does not play a role in regulating the fuel-to-air ratio. The pressure relief valve functions as a safety mechanism to relieve excess pressure in the boiler, preventing potential hazards without affecting the combustion process. Similarly, the safety control system monitors various parameters for safe operation but does not directly manage the fuel and air mixture during combustion.
