The energy needs associated with steam losses are influenced by a number of factors. These typically include the number of hours that the process is operating, the plume or leak size, and the steam flow, pressure and temperature. Refer to the Steam Plume Schematic, Steam Leak Schematic and Steam System Diagram for more information.

Software & Data
The RETScreen Software Steam Losses Model can be used worldwide to evaluate the energy use and savings, costs, emission reductions, financial viability and risk for steam losses energy efficiency measures. The software can model a wide variety of projects ranging from sealing safety valves in pulp and paper mills steam circuits, to leakproofing steam traps in brewery and petrochemical processes. In addition, the properties of water and steam can be calculated using a convenient Water & steam tool. The software (available in multiple languages) also includes product, project and climate databases, and a detailed user manual.
