What is the main function of turbulators in a boiler?

Turbulators play a crucial role in enhancing the heat transfer process within a boiler. They achieve this by creating turbulence in the flue gases as they pass through the boiler tubes. The turbulence disrupts the laminar flow of the gases, increasing the surface area in contact with the tube walls. This improved contact allows for more efficient transfer of heat from the combustion gases to the water or steam inside the tubes. As a result, the boiler can operate more effectively, maximizing the amount of heat extracted from the fuel being burned.

This function is essential for overall boiler efficiency, directly impacting the unit's performance and operational costs. By increasing heat transfer, turbulators help ensure that the energy produced from the fuel is used effectively, minimizing fuel consumption while maintaining optimal boiler output.
