The purpose of a baffle wall in a boiler is to distribute flame evenly. By incorporating baffle walls, the combustion gases are directed in a manner that maximizes the interaction between the hot gases and the water in the boiler. This efficient distribution is crucial as it ensures that the heat from the combustion process is evenly applied to the water, promoting better heat transfer and improving overall thermal efficiency. Enhanced heat distribution can lead to more consistent steam generation and reduced hotspots within the boiler, ultimately contributing to improved performance and safety.

While increasing water pressure, reducing noise levels, or acting as a heat exchanger could be associated with aspects of boiler operation or design, they are not the primary functions served by a baffle wall. Each of these elements serves specific roles in the overall functioning of the boiler but does not align with the fundamental purpose of the baffle wall, which focuses on flame distribution.
