Product Description
Steam Boiler Plant 120MW / 30 bar Saturated Steam
Good condition steam boiler plant for 54 kg/sec saturated steam at 30 bar production to an industrial process. The boiler is membrane walled, bottom supported and it has two natural gas fired and two light fuel fired 30 MW (each) burners located on the top of the boiler. The bottom of the firebox and the lower manifold are protected with refractory tiles. The boiler's flue gas side operates under overpressure and plant has two 100% combustion air fans and there is no exhaust gas fan. The equipment has been very well maintained and upgraded throughout its entire lifetime and meets today’s strictest quality requirements.
The steam boiler has natural water circulation, and the heating surfaces are arranged in two drafts: the convection surfaces (evaporator) are in the 2nd draft of the boiler and the feedwater preheater (economizer) is in its own separate draft. The burners use non-preheated boiler room air and the burners are equipped with air registers for vertical combustion. The register consists of a primary and secondary section. The burners are designed with low nitrogen oxide emissions in mind. The water temperature in the boiler feed water tank is approx. 137"C, which is the temperature of the feed water fed to the economizer.
The boiler plant consists of a feed water system, steam drum, light diesel fuel oil system, water desalination plant, steam and condensate systems and modern plant control system. The exhaust gases pass through a multicyclone for particle removal. The delivery includes service platforms, steel structures, wall and roof sandwich panes of the boiler room.
Steam plant operation and control system was totally rebuilt in year 2016 is currently based on Siemens T-3000 system with Siemens Simatic 7-series PLCs
