Energy-efficient steam supply for Symura Laundry
A boiler system supplied by Loos (now Bosch Industriekessel) was in use at Symura Laundry in Germany's Lower Saxony region for almost 20 years. Various investments were made in energy-efficient equipment over the years, with the result that the laundry required progressively less steam. The company's steam generator, on the other hand, was not updated and had originally been designed for a significantly higher nominal output than was now needed – meaning it was now no longer efficient to run. To exploit the available cost-cutting potential and ensure operational reliability, the laundry management decided to upgrade their steam supply. Together with specialist planner Gerd Steding of consultancy firm HLS-TECHNIK from Oldendorf, Hesse, they developed an optimal, cost-effective solution.
As a result, a cutting-edge U-MB steam boiler from Bosch Industriekessel was installed at the company. This new boiler has a steam capacity of 600 kg/h. It is fitted as standard with an economizer, which uses the heat in the flue gases to pre-heat the boiler feed water, allowing most of this heat to be recovered. Fuel consumption and emissions are now lower than before. The boiler's low-NOx natural gas burner with speed-regulated fan keeps it running optimally and at the same time reduces electricity consumption and noise emissions. To allow the boiler parameters to be set for the most efficient possible energy use, it is fitted with a programmable BCO boiler control. It also features an SUC start-up, standby and shutdown control for extra reliability and to facilitate automatic operation, which takes the burden off operating personnel.
Thanks to its compact and ready-to-connect design, the boiler could be very quickly moved into position and installed by the plant construction company AME-TECHNIK GmbH from Hamelin. It is regularly serviced by Bosch Industriekessel's customer service department, ensuring maximum reliability and consistently economical operation in the long term.
The new steam supply system saves the laundry around 9,300 euros in energy costs annually. It also cuts its CO2 emissions by some 46.6 tons per year.
"We chose Bosch primarily for their customer service and the excellent reliability of their boilers," explains laundry owner Oliver Symura.
