What is one advantage of using curved or streamlined baffles in a boiler?

• A. They simplify the construction process
• B. They reduce eddy currents and friction
• C. They are easier to clean
• D. They increase ash accumulation

Answer: (B)

Using curved or streamlined baffles in a boiler primarily offers the advantage of reducing eddy currents and friction. When fluid flows around obstructions or changes direction sharply, it can create turbulence, leading to eddy currents that increase resistance and energy loss. Streamlined baffles help to maintain a more uniform flow path for the water or steam, thereby minimizing turbulence. This efficient flow pattern reduces friction losses within the boiler, which can improve overall heat transfer efficiency and help in maintaining optimal operating conditions. Better flow movement also promotes more uniform temperature distribution and reduces the risk of hotspots, which can lead to localized overheating and stress on boiler materials. Hence, the design of curved or streamlined baffles positively impacts the performance and efficiency of the boiler system.
