The research on proper pulse pressure prediction of pulse air jet type bag filter using coke dust showed this result as follows.
1. Volatility of pressure loss by pulse pressure, under low dust concentration(0.5g/m3, 1g/m3) and slow face velocity(1.25m/min), was shown less than 10mmH2O; it suggests that pulse pressure gives low impacts on pressure loss. Contrariwise, volatility of pressure loss, under high dust concentration(3g/m3) and fast face velocity(1.75m/min), was maximum 25mmH2O. Therefore, pulse pressure with high dust concentration and fast face velocity has a strong influence on volatility of pressure loss compared to the condition of low dust concentration and slow face velocity.
2. Proper pulse pressure of inlet dust concentration(0.5g/m3) was 6kg/cm2 under same face velocity(1.75m/min). As concentration increases from 1g/m3 to 2g/m3, pulse pressure gradually appeared in 5kg/cm2 and it indicated that pulse pressure(5kg/cm2) is pertinent at a high concentration(3g/m3).
3. The pulse intervals; 20sec, 25sec and 30sec, which are relatively longer than 10sec and 15sec showed big volatility of pressure loss by pulse pressure, furthermore, it showed low volatility of pressure loss at 5kg/cm2 of pulse pressure over all.
4. On the other hand, Fig. 20 on high concentration demonstrated high pressure losses which are maximum 36mmH2O, 26mmH2O and 13mmH2O in comparison with Fig. 11, Fig. 14, Fig. 17 which have same face velocity. As a result of this, the concentration of inlet dust has a major influence on pressure loss.
