Failure of a Kiln Burner at a Cement Plant » Approved
May 24, 2017 The operation for Kiln 3 at a cement plant was stopped at 1125pm 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 combustionDec 05, 2020 re Kiln shell cooling fans arrangment In today's cement plant we can see both ways of placing the shell cooling fans ie on charge side and in some plants in opposite side of charge But practically it has seen that fans placed on charge side has better effect on formation of coating It is a kind of quenching effect on charge sideKiln shell cooling fans arrangment Page 1 of 1Accessing this course requires a login Please enter your credentials below!CEMENT KILN MAINTENANCE The Cement InstituteBucket Grate Coolers The first form of grate cooler used on British kilns was the Bucket Grate The cooler was built into a greatlyenlarged kiln hood, with length about 19 times the kiln diameter, and width 15% greater than the length A concave grateplate occupied Cement Kilns: Grate Coolers Cement Plants and Kilns in The hot clinker discharged from the kiln at a temperature of about 1300 C is further treated in clinker cooler The cooling of clinker influences its structure, main composition, grindability and consequently, the quality of the resulting cementCLINKER COOLING TECHNOLOGY Mechanical engineering
