A typical windbox model (scale 1:8) of one 600MW coal fired boiler ac measured for flow forms at the inlet of the windbox
the inlet and outlet of each chambers
and for properties of its destributed resisboce. According to these measurements
the chambers are divided into the deviation flow chambers and the uniform flow chaments. Based on the contribution characteristies across the outlet width of Windbox under different arrangements of the turning vane
an arransement of the turning vane to susaested for the optimum flow form at the outlet of windbox.
