A structured grid partitionfor full scale coal fired tangential utility boiler has been given in this paper. It hasa small amount of grids and can decrease false diffusion effectively as it is inagreement with fluid flow direction. Accurate simulating results can be gainedwith the grid partition. Inverse flows are captured near the wall at four corners incombustion simulating through the above grid and temperatures simulating agreewell with them measured.

The square-on-square grids set diagonally of half MERO joint have been analysed and compared according to a design example and more than thirty projects already constructed. The conclusion is that the steel con- sumption for the square-on-square grid with a span of 30 metres or so is most economical; the size and height of grid are the important par- ameters which affect the steel consumption to a high degree.
