Web10 de abr. de 2010 · Steam was the prime choice as a heat transfer medium. The advantages of steam were the availability, low cost of water, with no environmental issues. Effective Heat transfer by steam uses the latent heat. The saturation pressure dictates the temperature at which heat transfer takes place. Exceptionally high pressures would be needed for steam systems to deliver the kind of heat required in most process operations. A saturated steam system develops about 1600 psi at 600°F, for example. Pressure is about 235 psi at 400°F, which is still high. Conversely, fluid systems are mostly vented to atmosphere. … Ver más Efficiency has been indicated by thermal fluid heater manufacturers to be up to 5-8% higher than conventional steam systems.
