Quick and competent implementation: New boiler plant for Püls-Bräu
The experienced plant engineering company Ago AG from Kulmbach, Bavaria has implemented together with Bosch Industriekessel a new heating boiler system for the Püls-Bräu brewery in Weismain, Bavaria. A special challenge was to implement the boiler in a very short time: The project participants had seven days for demounting the old boiler, for positioning and installing the new boiler, and for the integration into the existing network. Any delay would have lead to high costs for the brewery, since the complete brewhouse depends on a reliable heat supply.
The brewery had fixed end of October as date for implementation, because the seasonal utilisation of capacities allowed for this short break in production. After demounting the old boiler on October 22, 2015, the new compact heating boiler, type UT-L, was quickly brought into the boiler house. In addition, the pre-mounted components, such as firing, flue gas heat exchanger and safety equipment saved lots of precious time for installation. Thanks to detailed previous planning and preparatory measures by Ago, the work was already completed at midday on October 28, 2015, and the responsible Bosch customer service engineer Andreas Imsel could start with commissioning. Start-up and setting of the plant went smoothly. The control equipment, already wired and tested previously at the Bosch factory, increased working efficiency and allowed for easier connection to the central control technology of the brewery. After having successfully tested the plant on functionality and safety, and after issuing the provided proof of performance, Andreas Imsel instructed the operating personnel from Püls-Bräu. The plant was optimally adjusted to the operating conditions at the brewery in a one-day test operation.
As usual, all systems were started up on Sunday evening and brewery operation commenced as planned – with a considerably difference: Now the heat supply of the brewery for mashing and cooking is much more efficient. The new heating boiler is equipped with a heat exchanger for heat recovery. The main fuel is natural gas. The existing oil supply is used as back-up in case of supply shortages in the natural gas network. The modulating dual fuel burner is optimally matched to the plant's requirements and saves a high amount of electricity with the speed-controlled burner fan. In total, the boiler efficiency is improved by about 15 percent compared to the previous plant from the 1970s. The overall communication and control, such as switchover to heat maintenance mode on weekends, is effected by the central control technology. Intelligent system features, such as efficiency forecast, help to minimize losses and facilitate operation. Thanks to high data transparency, the customer service engineer can analyse the operating data and, if necessary, make adaptions during his regular maintenance service checks – for continuous high efficiency.
