The new 44th German Emission Control Act (Bundes-Immissionsschutzverordnung; BImSchV) noticeably restricts the limit values for biogas cogeneration unit emissions; operators are facing particularly strict emissions limit values for nitrogen oxide (NOx). MAN Engines is prepared for the new limit values. Since early 2018, as a cooperation parter in a project initiated and financed by the Bavarian State Ministry of the Environment and Consumer Protection, it has been successfully testing its modular exhaust gas aftertreatment system at a biogas plant in the field.
The MAN E3268 LE242 is based on the E3268 with 370 kWmech, which was introduced in 2013, and has therefore been tried and tested in the field hundreds of times over. The V8 engine is available in a natural gas-optimised variant with a compression ratio of ε 12 : 1 and can also be used with biogas with a compression ratio of ε 13.6 : 1. Potential uses in current-regulated CHP applications (combined heat and power) range from the industrial and commercial to the municipal and recreational sectors.
MAN Engines is now offering a twelve-cylinder 450 kWmech gas engine based on the E32 series. Both The E3262 LE232, for natural gas, and the E3262 LE242, for biogas and other special gases, deliver 450 kWmech at 1,500 rpm (50 Hz). This means that MAN Engines has now bridged the gap in performance between 370 and 550 kWmech, which was previously covered by the earlier E2842 series.
EnergyDecentral: greater output and efficiency for MAN’s new E3262 naturally-aspirated engine
MAN Engines will be unveiling their new E3262 E302 natural-gas engine for co-generation plants at this year’s ‘EnergyDecentral’ trade fair. Thanks to stoichiometric combustion (λ=1), a three-way catalytic converter is all that is needed to reduce nitrogen oxides and carbon monoxide on this twelve-cylinder engine.
From 2016 there will be revised legislation for the cogeneration of heat and power, the Engine Competence Centre in Nuremberg will get its own cogeneration power station and over the past ten years six such power stations with MAN engines have been selected by the Federal Association for Cogeneration of Heat and Power as the cogeneration power stations of the year. Reason enough for MAN Engines to take a look at the area as a whole.
