Premium marathon ® combustion systems in worldwide operation… Installation example More efficiency through successful system conversion The organic brewery Lammsbräu in Neumarkt can look back on 200 years of tradition and they always have the future in mind. True to the motto of the family- owned company “Talking less, doing more – and doing the right thing”, many years ago, the course was set for a sustainable corporate concept. The new system in the boiler house also is based on this principle. Two hot water boilers from Bosch Industriekessel GmbH in combination with two gas burners marathon ® M 3001 ARZ continuously and sustainably supply the heat required for beer production. With regard to the central location of the brewery in the city center of Neumarkt, Lammsbräu placed great emphasis on the equipment of the burners with CO regulation in terms of increasing efficiency and clean air. The application of the patented internal exhaust gas recirculation ARZ leads to particularly low emissions, e.g. NO x < 75 mg. The compact design of boiler and burner with integrated Eco is also extremely advantageous in terms of sound emissions. Last but not least, the Brewery benefits from an optimal price- performance ratio through the combination of high-quality and efficient series products with system-specific fine tuning. The experienced and competent project team ensured a fast and smooth project process with guaranteed savings in energy consumption and costs. We would like to thank the brewery Lammsbräu, Bosch Industriekessel GmbH and all involved for the successful implementation of the project and their decision for the marathon ® burner technology. Useful information: dreizler ® oxygen – Combustion optimization With the oxygen control oxygen, the O 2 content in the exhaust gas is permanently and precisely determined and readjusted via particularly high-quality lambda sensors. As a result, the amount of exhaust gas and the resulting loss of exhaust gas are constantly monitored and minimized. When using gaseous fuels, the dreizler ® technology oxygen plus also offers the possibility of measuring unburned exhaust gas components via an additional exhaust gas probe and thus operating the burner with stoichiometric combustion approximately ( λ ~ 1).
