Large-scale boiler for French automobile manufacturer
The Bosch steam boiler ZFR-X, which is almost twelve metres long and over five metres wide, has been in operation now for several months at a French automobile manufacturer. The giant steel colossus with an operating weight of around 137 tonnes has a steam capacity of 50,000 kilograms per hour. It ensures a reliable heating and process heat supply in the production facility of the car manufacturer.
The new steam boiler from Bosch with its modern concept replaced an ageing water-tube boiler. The LCI Group from Carvin in France was responsible for the implementation and support on site as well as for the installation. Commissioning was also handled by this long-standing partner of Bosch Industriekessel.
The ZFR-X is a shell boiler with three-pass technology and two flame tubes, as well as completely separate flue gas paths. An integrated superheater module on the boiler generates superheated steam instead of saturated steam, which means that temperatures of up to 230 °C can be achieved.
The steam boiler is equipped with an integrated economizer to use the heat potential within the hot flue gases. Feed water is fed into the heat exchanger and preheated to approx. 140 °C. The flue gas temperature falls to approx. 130 °C during this process. This not only saves energy, but also protects the environment. Use of a highly-developed natural gas burner system ensures that combustion produces reduced pollution with particularly low NOx emissions. Speed control helps to reduce the power costs and sound level in the partial load range. The burner system is also equipped with oxygen control. The excess air in the flue gas is reduced to a minimum, in order to ensure effective combustion and therefore achieve greater efficiency.
This is yet another occasion, when the French automobile manufacturer has opted for the proven boiler technology of Bosch. In addition to the new steam boiler the company operates four hot water boilers UT-HZ and one steam boiler UL-S at various sites in France.
The steam boiler ZFR-X with integrated economizer and superheater module has an operating weight of around 137 tonnes.
The modern natural gas burner system provides low-pollution combustion.
