press release

Following an extensive site analysis, the dairy operated by Immergut GmbH & Co. KG in Schlüchtern, Hesse, decided to opt for a new energy concept. The new system comprises a waste heat boiler with self-firing from Bosch Industriekessel and a combined heat and power unit (CHP unit). The CHP unit uses the combined heat and power cycle to generate approximately 30 per cent of the power required by Immergut. The self-fired waste heat boiler converts the waste heat that accumulates from the engine into process steam via its additional fourth smoke tube pass. The steam is primarily used for sterilisation in the dairy's production process. A separate flue gas heat exchanger connected downstream from the fourth smoke tube pass further increases efficiency. An additional peak-load boiler was not necessary due to the use of the design variant with self-firing. This enabled investment costs, space requirement and expenditure on equipment to be reduced accordingly.


In addition to the UL-S type waste heat boiler with self-firing, the system also includes modular components from Bosch Industriekessel for water treatment, heat recovery and control. These provide more energy efficiency, a higher efficiency rating and increase operational reliability. The plant construction company Helmut Herbert GmbH & Co. from Bensheim placed the order for the waste heat boiler with Bosch Industriekessel and was responsible for all aspects of the planning and construction of the new energy system.


The new energy concept, which significantly increases efficiency compared with separate electrical power and heat generation, will pay for itself within less than six years. At the same time, by reducing its CO2 and NOx emissions, the dairy is contributing to the protection of the environment. Previously, Immergut had been using a steam boiler manufactured by Loos International (now Bosch Industriekessel GmbH) in the year 1970.
