Mannheim, April 22, 2021<\/p>\n

Andechser Molkerei Scheitz GmbH, based south of Munich, Germany, produces dairy products such as curd, butter, and cheese from the milk supplied by organic farms. For this, the company needs energy as well as heat, cold, and compressed air for heating the milk in the production process. To ensure sustainable energy management and preheating of the products, internal heat sources are made use of. Apart from an MWM gas engine<\/a>, a compressed air cogeneration power plant and an absorption chiller are used to supply the dairy operation with energy, heat, and cold. “Energie & Management” magazine has designated the cogeneration power plant with the the MWM gas engine as “Cogeneration Power Plant of the Month” of March 2021.<\/p>\n

Gas Engine Exhaust Heat Used to Produce Hot Water<\/h2>\n

The cogeneration power plant consists of a natural gas-fueled MWM TCG 2020 V12 gas engine<\/a> with a boiler output of 2,380 kW. The connected generator delivers 999 kW of electrical energy. For the steam generation, the exhaust gas from the gas engine is cooled down from a temperature of 413\u00b0C to 190\u00b0C. Before the exhaust gas enters the boiler, it is treated in an oxidation catalyst. The exhaust heat from the engine produces hot water, which is post-heated by means of an exhaust heat exchanger. The absorption chiller generates about 431 kW of cold.<\/p>\n

Primary Energy Savings of up to 30 Percent, Carbon Emissions Down 1.6 Million kg\/Year with Cogeneration Power Plant for Distributed Energy Generation<\/h2>\n

To ensure power-controlled operation of the cogeneration power plant, the trigeneration plant is included in the controls of the boiler and chiller systems as base load capacity. Thus, the system is able to run under full load for at least 7,500 hours\/year. “As we will additionally use the energy of the mixture cooler\u2014which is normally lost\u2014at a temperature of 60\u00b0C for our hot water generation, the plant’s total efficiency rises to 91 percent”, explains Josef Scheuermeyer of the Energy, Environment, and Sustainability Management of Andechser Molkerei Scheitz GmbH. In combination with the absorption chiller, the cogeneration power plant saves 30 percent of primary energy and up to 1.6 million kg of carbon a year and cuts the dairy company’s power and fuel costs.<\/p>\n

Optimized Energy Management with Cogeneration and Trigeneration<\/h2>\n

Compared to the separate generation of electrical energy and heat, cogeneration and trigeneration plants make much better use of the primary energy. MWM cogeneration power plants<\/a> enable economically and ecologically efficient energy generation. The plant transforms the utilized energy into electrical energy and heat right on site. The resulting exhaust heat can be reused directly and is not lost. Viable fuels include natural gas, biogas, waste gas, or other gases. The power generated by the cogeneration power plants can be consumed on site or be fed into the public grid for a feed-in tariff.<\/p>\n
