The water vapour pump (WVP) system is a wet combustion process developed and patented in 1979 by Dr Rémi Guillet, of Paris-based company CIEC, which has been part of the Engie Group since 2004. It consists of pre-heating and saturating the ambient combustion air with sensible and latent heat (humidity) recovered from the flue gases.

If the boiler is of a moderate size producing 10,000 kg per hour of steam, it uses about 10,000 litres per hour of water, in turn producing 60 cm³ of nitrogen. This will cumulate over time with a significant effect on heat transfer if not removed from the system.

Controlling CO boilers - DigitalRefining

Increased steam demand requires increased air and fuel flow into the boiler to maintain a constant combustion excess air set point while the bulk flue gas temperature is allowed to vary. However in the CO boiler, all of the CO in the flue gas stream delivered to the boiler must be burned thereby requiring a relatively constant combustion chamber temperature.
