Given the boiling point of water and ignoring the dew point effects of SOx, surely by definition air at anything above 100 deg C and atmospheric pressure will hold a infinate amount of water ... in the form of steam.
Keeping a dryer exhaust stream above 100 deg C when drying biomass is the challenge, given that evaporating water takes such an large amount of energy. By my back of the envelope calculation 60 kg of 120 Deg C air is needed to evaporate 1 kg of water (if the air is cooled to 100 deg C in the process) Regards, James -----Original Message----- De: Ken Boak <[email protected]> Asunto: Re: [Gasification] engine exhaust relative humidity Para: "Discussion of biomass pyrolysis and gasification" <[email protected]> Fecha: jueves, 16 de diciembre de 2010, 8:39 ... For example 100m3 of air at 120C can hold 35kg of water vapour before it becomes saturated ( or 100cuft can hold about 2lb of water at 250F). _______________________________________________ The Gasification list has moved to [email protected] - please update your email contacts to reflect the change.
