| Abstract: | With the help of a three-dimensional particle dynamic analyzer a measurment was performed of the return flow zone flow field of a pulvetized coal burner equipped with a combustion stabilization cavity and a comparison was made of the return flow zone characteristics at various locations of a bluff they. The authors practice has shown that through an adjustment of the location of the bluff they and the change of some structural dimensions of the abevecited burner it is possible to achieve a significant improvement of the combustion stability when burning various finds of coals. |
