Flue Gas Temperature @ Eco inlet, TGin = 435 Deg C

Flue Gas Temperature @ Eco outlet TGout = 245 Deg C

Feed water Temperature @ Eco inlet TWin = 105 Deg CFeed water Temperature @ Eco outlet

TWout = 175 Deg C

Flue gas volume flow rate @ 435 Deg C = 27.91 m3/sec

Existing Heat Transfer Area = 212.45 m2

Flue Gas density @ 0 Deg C = 1.2 Kg/m3

Flue Gas density @ 435 Deg C = (1.2 x 273) / (273 + 435)

Flue Gas density @ 435 Deg C = 0.46 Kg/m3

Tube OD 50.8 mm

Straight length (Bend to Bend) 3200 mm

No of straight length segments 64 Nos

No of loop 7 Nos

Casing Width 1100 mm

Casing Length (Excluding baffle plate) 3277 mm

Flue gas volume flow rate at Eco I/L (435 Deg C) 27.91 m3/s

Available area for flue gas flow 2.44 m2

In the modified Inline Design we can increase the Straight length (Bend to Bend) up to the 4200 mm Max. We don’t have the margin on Casing Width.
