  • Improving Energy Efficiency of Boiler Systems

    The procedure for calculating boiler efficiency by indirect method is illustrated below. 1) Dry Flue Gas Loss (LDG) Heat is lost in the "dry" products of combustion, which carry only sensible heat since no change of state was involved.

  • Drying to -20C Dew Point - Boiler and Pressure Vessel

    Sep 13, 2016 · If the pressure vessel temp is say a min of 10degC at this location while the vac pump is in operation, we have saturation vap pressure for water to be 9.2mmHg = 1.2kpa abs. So if the vac pump reading drops below this pressure (or some safe value below 1.2kpa abs), then this is a sign that there is no more liquid water in the vessel.Get Price
