MAN Rollo supplies combined heat and power plants (CHPs). The efficient conversion of biogas to heat and electricity is suitable for numerous applications. Henk van Oosten, owner of a mixed farm in Friesland, the Netherlands, recently purchased a MAN E2676LE biogas engine for his fermentation facility, with which he generates green energy from manure and organic waste.
High return and lower emissions
Because the European standards on permitted emission levels are becoming stricter in 2017, Henk van Oosten decided to purchase the new MAN E2676LE biogas engine. The engine is efficient and gives a high return with lower emissions. “The new E2676LE can comply with the 1/2 TA Luft emission level without requiring flue gas scrubbing. This is a lower emission level than will be required in the Netherlands this year,” says Dennis van Leeuwen, Powergen Sales Manager at MAN Rollo.
Henk van Oosten currently has four CHPs powered by MAN engines with varying power levels. The engines easily meet Van Oosten’s expectations. „Biogas can vary in quality, but MAN engines easily manage 8,000 operational hours per year nonetheless,“ says Henk van Oosten.
Heat utilisation and 6 million kWh per year
Van Oosten uses the generated heat to dry manure intended for export, and to heat his own home. In total, 80 to 90 percent of the heat is used. He also aims to achieve the highest possible conversion of biogas to electricity. Henk van Oosten delivers over 6 million kWh per year to the grid, which is enough to power approximately 2,000 households per year.
Four engines with generating capacities of 190, 210, 340 and 520 kWh
Input (per year): approximately 9,000 tonnes of fresh manure, 8,000 tonnes of other organic waste
Net output (per year): 6 million kWh of electricity
