Chain conveyor troubleshoot guide

  Problem Identification & Corrective Action Sl No. Problem Potential Cause Solution 1 Chain rises off from sprocket 1.Excess chain slack. 2.Excess wear at the bases of sprocket teeth. 3.Excess chain extension. 4.Foreign material stuck to the bases of sprocket teeth. 5.Reverse rotation of conveyor 6.Uneven chain tightening of chain 1.Adjust the amount of slack equally at both sides. 2.Carryout hard facing of the sprockets 3.Replace the elongated chain parts. 4.Remove the foreign material from the bases of the teeth. 5.Avoid reverse rotation of the conveyor when chain tightened is uneven 2 Chain separates poorly from the sprocket. 1.Sprocket misalignment. 2.Excess chain slack. 3.Excess wear at the bases of sprocket teeth. 4.Uneven chain tightening of chain 1-Adjust alignment. 2-Adjust the amount of slack.

Question & Answers on ESP troubleshooting

                                   ESP TROUBLESHOOTING GUIDE 1-What are the potential reasons for large dust collection on collecting plates & discharge electrodes? Higher dust load on ESP Improper rapping Low velocity of flue gas Higher resistivity of ash ESP running under capacity 2-Why there is sparking in the fields? Excessive dust formation on plates Very less gap between collecting plate & emitting electrodes Improper alignment of electrodes Obstacle of foreign material in the field & touching the discharge electrode Improper charge ratio 3-What are the reasons for higher emission at stack outlet? Under size ESP or wrong design Improper rapping Higher spark rate Improper distribution of flue gas Transformer not working or under capacity 4-What are the reasons for damage/corrosion of ESP electrodes & casing plates? Operation of ESP at lower flue gas temperature <120 deg C continuously More ash
