2017-5-24 The operation for Kiln 3 at a cement plant was stopped at 11.25pm due to red spot (brick failure).Investigation indicates that the air channel pipe was “missing”, which resulted in a distorted flame shape. This is because the primary function of the air channel pipe is said to shape the flame and swirl the air whilst introducing the coal dust, to enable efficient combustion.
