Due to their inherent construction features, our vertical heat recovery steam generators are naturally well fit for cycling and provide optimal performance during frequent start-ups and shut-downs.
Optimized erection time, resources and costs savings
When projects involve reduced footprint, vertical gas flows across serpentine heat exchanger and no superheater quenching are ideal. A vertical design facilitates internal accessibility, which improves maintainability and reduces generator maintenance costs (cleanability). In addition, our vertical HRSG modules offer a high level of prefabrication, allowing hydrotest in workshop and easier and cost-effective erection with hydraulic lifting instead of large cranes.
This vertical design applied to Once Through Boiler technology is one of the latest innovative solutions from our teams of experts and design engineers. Without any high-pressure drum, they guarantee optimized increasing pressure power, high efficiency and the ability to support unlimited daily cycling, while being more economical.
References that speak for themselves
As our reference list (available for downloading) shows, the John Cockerill HRSGs have proven to be strong, and reliable boiler choice for 1967.
