It's no secret that many industrial facilities have an annual outage period, also referred to as a shutdown or a 'turnaround', during which production slows or ceases entirely and maintenance repairs take place across the entire facility.
You are probably not familiar with English actor Christopher Parker, but there is a quote attributed to him that is good to know: "Procrastination is like a credit card: it's a lot of fun until you get the bill." It is common knowledge that putting things off until the last minute tends to have poor results, however, sometimes it simply cannot be helped, can it?
When a steam or hot water boiler satisfies the high limits of the pressure or temperature demands that have been set on its controls, it will cycle off. The problem is that when this occurs while demand is still present, the boiler will quickly be needed back online; this is known as “short-cycling.” Most process and heating systems do not have a steady load--the load will actually vary based on production schedule, changes in outside air temperatures, or other variable factors. The inefficiencies associated with this cycling process are costly.
