What function do baffles serve in water tube boilers?

Baffles are critical components in water tube boilers, as they are designed to enhance heat absorption by deflecting gases effectively. The arrangement and positioning of baffles in the boiler help direct the flow of flue gases in a manner that maximizes the contact surface area with the water tubes. This promotes efficient heat transfer from the gases to the water, ultimately improving the boiler’s overall thermal efficiency.

By guiding the gas flow, baffles also help ensure even heating throughout the system, which can contribute to more stable operation and reduced thermal stress on the boiler components. This functionality of baffles is essential for maintaining optimal performance in a water tube boiler setup.
