Immergut Molkerei – four-pass boiler paves the way to a modern energy concept
The origins of the Immergut GmbH & Co. KG, a manufacturer of dairy products go back to the founding of the Molkerei Stavenhagen in 1883. The company’s works in Schluechtern, Hesse followed 11 years later. 1930 saw the opening of the Molkerei A. Ziegler in Schluechtern, which took over the Immergut ‘West’ brand in 1964. 13 years after German reunification, the Immergut ‘West’ and ‘East’ brands finally came together, followed shortly by the foundation of Immergut GmbH & Co. KG in Elsdorf.
The dairy products manufacturer has relied on boilers from LOOS INTERNATIONAL (now Bosch Industriekessel GmbH) for the production of process steam since 1970. The steam is employed primarily for sterilisation in Immergut production processes under strict consideration of the company’s quality criteria. Following an extensive site analysis, and in collaboration with Helmut Herbert GmbH & Co., plant engineers from Bensheim, the company decided to take advantage of combined heat and power generation to satisfy their extreme energy requirements. A CHP system was chosen for on-site power generation. The exhaust heat from the motor of this system is transformed into process heat in a series-connected, self-fired four-pass boiler from Bosch Industriekessel. With this option, peak-load boilers may frequently be omitted due to self-firing. The investment costs, the space required for installation and costs for ancillary equipment are reduced to an enormous extent.
On-site power generation with the CHP in conjunction with waste heat exploitation by the high-efficiency steam boiler and heating system leads to a considerable increase in efficiency in comparison with separate electrical power and heat generation.
We would be pleased to arrange a personal meeting to determine an optimum heat concept to meet your specific needs or discuss project-related issues.
The waste heat from the CHP systems is transformed into process steam by an additional exhaust heat string in the boiler system.
