As part of the process of upgrading their instrumentation, Preem, in Lysekil, has purchased new flame scanners during the past year for two plants. They chose to purchase the Fireye Insight II DSS3 flame scanner, which is the latest in the flame scanners range. The scanner is suitable for most combustion applications, considering its wide range of options, and its superior discriminating ability. It can be used advantageously by plants with many different combustion processes, where you would like to have only one product that meets all the needs. This reduces spare parts maintenance and facilitates maintenance.

SES Combustion has currently supplied and commissioned nine units for a boiler, as well as two units for a sulphur combustion application.

Nynas AB, the oil refinery located in Nynäshamn, had an audit shutdown during the spring of 2015, for the review and maintenance of its plant. As part of this project, a burner in one of the plants was replaced with a new one. At the subsequent start of the plant the older flame scanners failed to confirm the flame in the lower load register. SES Combustion was contacted and the following day we installed and commissioned a Fireye Insight I DSS2 flame scanner. The flame scanner was a loan while awaiting the ordering and delivery of new equipment.

Since September 2015, Fireye Insight II DSS3 flame guards have now been delivered and commissioned by SES Combustion at Nynas AB.

Södra Cell reconstructed a black liquor recovery boiler at Mörrums’ paper mill in the autumn of 2015. SES Combustion was as a proud subcontractor of well-known Valmet and delivered the following equipment:

• 7 pcs Fireye Insights I DSS2 flame scanners
  • 4 pcs Hegwein ZA0 ignition burners
  • 9 pcs UNI Geräte 03-EVA5 valves, type approved according to EN 161

In conjunction with rebuilding at SSAB’s power station in Oxelösund in 2013/2014, 8 pcs burners on boiler 1 and boiler 2 were exchanged. SES Combustion was responsible for the delivery and commissioning of the equivalent number of flame scanners, Fireye Insight I DSS1.

In 2015, SES Combustion also performed consultancy work on the current installation to solve discrimination issues arising from the narrow placement of the burners.

The plant is currently operating as it should, and all burners on both boilers are individually operating smoothly.

As a proud sub supplier to well-known Diamond Power, SES Combustion delivered a new sootblower control system during the summer of 2015 to Kungälv Energi.
The system is PLC-based with capacity to handle up to 24 pcs soot blowers and five different sooting sequences in 64 steps with associated graphical HMI.
Because it is designed to handle a wide range of applications regarding sensors, valves and blow functions the system can be adapted to the specific application. This reduces both price and delivery time.
The scope of delivery included also dismantling of old system, installation and commissioning at end customer site.

During 2014 SES Combustion delivered a new BMS to the black liquor recovery boiler at Aspa bruk and we also delivered following associated equipment:

• 6 pcs flame igniters, Hegwein ZA0
• 6 pcs flame scanners, Fireye Insight I DSS2
• 6 pcs complete valve sets with valves from UNI Geräte
• SES Combustion also did the commissioning at customers site.

During summer 2015 the gas combustion was updated at Billingsfors Bruk.
SES Combustion delivered and installed a new burner control system from Fireye (BurnerLogix and flame scanner Insight I DSS2) and type approved valves in line with EN ISO 23553-1 from UNI Geräte.
The exchange took place because of an old burner control system is obsolete and to change valves that are approved in line with modern standard.
Similarly changes has been made before at the site because of same reason.
