Process steam


The energy performance of a process steam system is influenced by a number of factors. These typically include the number of hours that the process is operating, the steam flow, the steam pressure and temperature, the amount of condensate that is returned to the steam generator and its temperature, and the makeup water temperature. Refer to the Typical Steam Circuit and Steam System Diagram for more information.

Software & Data
The RETScreen Software Process Steam Model can be used worldwide to evaluate the energy use and savings, costs, emission reductions, financial viability and risk for process steam energy efficiency measures. The software can model a wide variety of projects ranging from soot blower operation time reduction by monitoring boiler performance in pulp and paper mills, to steam demand reduction by reducing percentage of evaporation in brewing kettles and by controlling adequately the pressure in deaerators in the pulp and paper, food and beverage and petrochemical industries. 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.
