Gas Engines For Biogas CHP
(0 votes)
Gas engines correspond from the working principle internal combustion engines. They can be pursued exclusively, i.e. to 100%, with biogas and take methane concentrations of more than 70% easily. In comparison to dual fuel engines they have mostly a higher electric achievement. what she predestines for bigger arrangements. With Dreyer & Bosse you receive gas engines with an electric achievement between 104 to 717 kW.

Standard conditions according to DIN ISO 3046 (air pressure 1000 mbar, air temperature 298 K, humidity 30%)
Performance data for biogas HU = 6.0 - 6.5 kWh/Nm3, depending on several engines.
Performance data for other kinds of gas on request at Dreyer & Bosse.
Cooling water qualities according to engine manufacturer' s instructions.
Motor oil qualities engine according to engine manufacturer's instructions.
Efficiency data are subject to a tolerance up to 5% due to permissible errors, varying basic conditions and fluctuations in the fuel condition.
In co-generation plants efficiencies of up to 90% are attainable related to the primary energy. Which amount of heat can be used in detail, depends on the technical conception of the overall system.
