Optimization of Steam Levels

However, it is important to understand where there is scope to improve an existing system, even if changes cannot be justified economically. Steam systems change over many years, and the demands on them change correspondingly. If the existing steam system is understood properly, then longterm infrastructure investment can steadily improve the system, even if short-term investment cannot be justified. 

If a new steam main is added to an existing system, then there are two ways in which the system can benefit13. 

Whilst adding a new steam main across an existing site is likely to be prohibitively expensive, a local (as opposed to sitewide) steam main between a few critical processes might allow much of the potential improvement to be realized at much lower capital cost.
