OptiAir Recovery

Heat recovery systems for energy efficient paper and board making

Heat recovery plays a crucial role in energy-efficiency and in creating stable drying conditions. It provides excellent opportunities for reducing costs and increasing profitability. OptiAir Recovery is a part of Valmet’s OptiAir family which is designed for optimal and controlled drying conditions and working environment for paper and board machines.

Heat recovery reduces energy costs

Main purpose of heat recovery system is to replace primary energy with recovered heat from the process in an economically profitable way. Total heat recovery in a modern paper or board machine can be over 50 MW. This is equivalent to 86 t_steam/h, therefore the energy flows are significant. It is important to utilize this energy efficiently. OptiAir Recovery heat recovery solutions provide excellent possibilities for optimizing the energy and air flows in paper and board making.

Recovered heat can be used to heat:

dryer section supply air
fresh water
white water
machine room ventilation air
air dryer combustion and make-up air

If you suspect that your heat recovery system is not performing properly, let our process survey group analyze your system and recommend what can be done for the machine’s energy efficiency.

Main benefits of OptiAir Recovery system:

recovered heat replaces primary energy
lower fresh water consumption with closed process where evaporated water is returned back to the process
heat recovery equipment efficiently reduces environmental noise level
an automatic cleaning system takes care of the daily cleaning
