VAPOUR CELLS / EVAPORATORS Concept of Vapour Cell Evaporators

Earlier the common Evaporation Systems were straight Quad or Triple or sometimes Quintuple. With passage of time bagasse use was diversified for paper Industry and Cogeneration. In between high pressure boilers and more efficient Evaporator Systems like Semikestener and Falling Film Evaporator entered the Industry and this development changed the whole scenario. The new inventions created immerse possibilities of vapor bleeding and subsequent steam economy. The concept of Vapour Cell and then Double Effect Vapour Cell was gradually accepted with advent of low retention time Semikestener /Falling Film Evaporator. Factories even installed reducing pressure Evaporators which could not be thought about earlier due to inversions and sugar destruction chances in case of old Robert Type Evaporators.

With proper de super heating arrangement of exhaust steam and auto controls, the chances of sugar/reducing sugar loss have receded to quite considerable extent. With modern arrangement as explained above people have achieved steam consumption figure even upto 42-43% as average during season and recorded figure even below upto below 40% cane. Even with low pressure boilers of 18 kg/cm2 and exhaust steam at 0.76 to 0.78 kg/cm2 the steam consumption could be brought down to a record low figure of 46-47% cane with DEVC and Quad by adopting maximum possible vapour bleeding available vessels.
