Shantou Unit 3
stage 1each40min 1.5times per hour
stage 2each40min 1.5times per hour
stage 3each60min1times per hour
4flushings of stages per hour
with5valves each flushing stage and0.6min flushing time for each valve =3min each flushing stage
with4flushings of stages per hour there are12min flushing time per hour
for 100% flue gas flow rate are48min pause time per hour needed48min/4flushings are12min pause time for 50% flue gas flow rate are 50% of the water amount is needed
therefore for 2 hours the same amount of water is needed as for 1 hour at 100% flue gas flow rate
120 min -12min =108min108min/4flushings are27min pause time I:100 = m *12+ b
II: 50 = m *27+ b
II - I:- 50 = m * 1515
m = - 50 / 15 15
m =-3.33
b = 100 - (m * pause time at 100% flue gas)
b =140
100 equal 100% flue gas flow rate = 1,296,650Nm³/h trocken
D = 1.4 * flue gas flow = 1,815,310
K1 =-0.03 * flue gas flow = -43222
