Reboiler with hydraulic loop to condensate drum liquid hammer problem
I think the boilling of condensate in the LOOP cause the problem. Suppose there is no condensate flow at the end of cycling, the steam pressure in the reboiler is lowest at this condition and cannot push the condensate to the condensate drum. Remember that condensate temperature is lowest also...- nakagawa
