A kraft paper mill in Eastern India.

Impact on machine production due to poor condensate evacuation.

Poor condensate recovery (65%).

High back pressure (2.5 barg) in main common tank.

Boiler pressure not maintained.

High specific steam consumption (2.1-2.2 ton per ton of paper).

To optimise specific steam consumption with improve productivity and condensate recovery factor.

Forbes Marshall carried out a detailed study of the plant and engineered a thermal grouping cascade

based solution for effective utilisation of flash steam, along with with the following solutions :

- Steam flow meter and condensate flow meter.

- Pressure, differential and level control loops.

- Mini distributed control system.

Specific steam consumption brought down to 1.6 - 1.7 ton per ton of paper.

Improvement in condensate recovery - from 55% to 90%.

Boiler pressure maintained at desired levels.

Realtime monitoring and control of all parameters.

6% increase in productivity.
