Improving boiler sequencing efficiency

When meeting steam demand with the wrong boiler mix increases fuel use

Customer scenario

A manufacturing site operated four boilers to provide the steam required by production. Boiler-efficiency calculations in Strata showed that Boilers 1, 2 and 3 were significantly more efficient than the larger 800 HP Boiler 4. By changing the operating sequence, the site could meet demand with the more efficient boilers and reduce gas consumption.

What our energy experts revealed

Boiler efficiency varied across the boilerhouse

Insights icon

Efficiency calculations showed that Boilers 1, 2 and 3 materially outperformed the larger Boiler 4.

Existing assets offered a lower-energy operating strategy

Arrows showing upward trends

The opportunity was to increase utilisation of Boilers 1, 2 and 3 and take Boiler 4 offline during normal operation.

Normal sequencing was increasing fuel use

Engineering icon

The less-efficient 800 HP boiler was being used when the smaller, more-efficient boilers could meet demand.

From insight to action

1. Analyse

Boiler-efficiency data and the factory gas KPI were analysed across the four boilers.

2. Interpret

Engineering analysis identified the efficiency gap between Boilers 1, 2 and 3 and Boiler 4.

3. Improve

The boiler sequence was changed to prioritise the more-efficient units during normal operation.

4. Acheive

The boiler sequence was changed to prioritise the more-efficient units during normal operation.

Why boiler sequencing matters

Boilers of different sizes and configurations do not necessarily operate at the same efficiency. When a less-efficient boiler is used ahead of more-efficient available units, the boiler house can consume more gas than necessary while still meeting steam demand. Comparing boiler efficiency and sequencing operation around the most efficient available assets can reduce fuel use without changing the production requirement.
