Capacity The capacity of the boiler is 4000kg/hr. Converting to Tons/day 4000 x 24/1000 = 96Tons/day There are 2 boilers, then total = 96 x 2 = 192Tons/day Example calculation So total steam generated is 192 Tons/day Data shows condensate return as 25% of this value So condensate return = 192 x 0.25 = 48 Tons
