Software Tools to Boost Steam System Efficiency

There are various software tools that help facilities to evaluate steam systems and identify improvement opportunities. Some examples include:

  • Steam system scoping tool  quickly evaluates the plant’s entire steam system and spots areas offering best improveent potentials. It offers suggestions on various methods to save steam energy and boost productivity. It profiles and grades steam system operations and management from user input on steam system operating practices, boiler plant operating practices, and distribution and recovery practices, and then compares user’s steam system operations against identified best practices.
  • Steam system assessment tool (SSAT) develops approximate models of real steam systems to quantify the magnitude (energy, cost, and emission savings) of key potential steam improvement opportunities. SSAT contains all the key features of typical steam systems – boilers, backpressure turbines, condensing turbines, deaerators, letdowns, flash vessels, and feed water heat exchangers. The tool analyzes boiler efficiency, boiler blowdown, cogeneration, steam cost, condensate recovery, heat recovery, vent steam, insulation efficiency, alternative fuels, backpressure turbines, steam traps, steam quality, and steam leaks. Its features include a steam demand savings project, a user-defined fuel model, a boiler stack loss worksheet for fuels, and a boiler flash steam recovery model.
  • 3E Plus is a software tool that helps users to determine optimal insulation thickness, thereby reducing energy consumption and avoiding excessive expenditures. (APP, 2010. p. 113)
