Bosch plant in mobile boiler house provides oil terminal
Inter Terminals Oil Storage Company SGOT from Denmark operates seven oil storage tanks at its Stigsnaes terminal with a total volume of 406,000 m³. In order to ensure optimum stockpiling of oil, the oil storage tanks must be maintained at a temperature of 55 °C. A new Bosch steam boiler system with a performance of 4,500 kg/h is being used for this purpose.
The oil terminal possesses an extensive steam network with a multitude of pipes. The steam boiler UL-SX is equipped with a superheater module in order to prevent condensation and unnecessary energy losses on the way to the consumers. The steam is superheated to 195 °C which is 30 °C higher than the saturation temperature at the operating pressure. When combined with the corresponding boiler and system technology in a modular design, the operator can enjoy an efficient and reliable energy supply:
- Integrated economiser uses heat potential from the boiler flue gases to preheat feed water
- Modern natural gas firing increases efficiency and minimises emissions
- Using a speed control ensures low power consumption and reduced sound volume in the partial-load operational range
- Combustion-optimising control system which monitors the remaining oxygen content in the flue gas keeps fuel usage low
- Water service module WSM-V provides the boiler with thermally treated feed water and takes care of desalting and blow-down
- Automated operation via innovative boiler and system control BCO/SCO
- Transfer of all information relating to operation, to a central monitoring system by means of Profibus-DP
Robert Bosch A/S, together with plant construction company Vagn Hansen A/S were responsible for the overall boiler systems engineering. They also provided support during development of the bespoke boiler house. It can be moved flexibly on the oil terminal as required.
The complete Bosch system is situated in the mobile boiler house on the Stigsnaes oil terminal.
