1007Cold State Air Draught Commissioning Procedure(090317)

Commissioning Procedure for Cold State Air Draught

furnace is -50~-100 Pa, write down the operational parameter. Check the fans and the vibration of the air duct.

6.2.3. Increase the air flow to 50％BMCR、75％BMCR、85％BMCR, keep the negative pressure of the furnace normal, write down the operational parameter. Check the fans and the vibration of the air duct

6.2.4. Keep the air flow is 85%BMCR, increase the main primary air duct pressure to10kPa, check the leakage.

6.2.5. Keep the air flow is 85%BMCR, measure secondary air flow and record secondary air flow and different pressure displayed at DCS. Get flow transducer coefficient by calculation.

6.2.6. Increase the opening of the PAF to 85~95%, measure mill outlet air flow and record the same flow displayed at DCS. Get flow transducer coefficient by calculation. Measure air velocity of mill outlet pipes and measure the same velocity by temporary measuring devices. Get temporary measuring devices coefficient by calculation.

6.2.7. When all jobs shown above have been finished, balance the velocity of the primary air pipes.

6.2.8. Change the opening of the hot/cold dampers, write down the operational parameter.

6.2.9. Change the opening of the second air dampers of the wind boxes, ensure the dampers can work normally.

6.2.10. The commissioning result records are shown in appendix 5.
