What is the function of baffles in a boiler?

Baffles in a boiler serve the essential function of directing the gases of combustion so that they come into close contact with the heating surfaces. This increased contact enhances the efficiency of heat transfer from the combustion gases to the water in the boiler. By facilitating better contact between these elements, baffles help to maximize the energy transfer, which in turn improves the overall efficiency of the boiler system.

The design of baffles can also contribute to the proper routing of gases, ensuring that all areas of the heating surfaces receive adequate exposure to the combustion gases. This operational aspect is crucial for maintaining optimal performance and efficiency in steam generation processes. Thus, the presence of baffles significantly aids in achieving effective heat exchange, which is vital for a boiler’s operational success.
