The super-heater (SH) tubes in an incinerator have been locally corroded by nonuniform partially accelerated gas flow. It effects maintenance and cost performance. In order to level the gas velocity at the super-heater entrance, putting a baffle in a boiler may be effective. The leveling effect of a baffle was studied by using a three-dimension model and employing PTV (Particle Tracking Velocimetry) analysis. After some trial and error, a baffle configuration was found to give the reduction of maximum velocity and standard deviation of the gas flow.
