  • What Causes Steam Coils to Fail? - Campbell Sevey

    The more liquid it contains, the worse the quality. Some steam boiler manufacturers will guaranty steam with a quality of 99.5%. That's 99.5% steam and 0.5% liquid, usually in the form of very small droplets. Though it may leave the boiler very dry, by the time it gets to the point of use, like a steam coil, it may have degraded to 80% dry or Get Price
