Cascade Based Paper Drying System
The Forbes Marshall cascade based paper drying system is ideal for use in cases where available pressure is between 3.5 to 4.5 barg, or in cases where turbines are present.
In this system, fresh steam is supplied to the different dryer groups, and presurre is controllled individually for each group. This steam partialy condensates in the drying clyiner and the energy is transfreed to the paper via the drying cylinder shell. Blow through steam and condesate are removed from the drying cylinder into condesate tanks and passed on to lower pressure groups. The condsate is collected into the main condesate tank and pumped back to the boiler feed water tank.
