Peaker plants are generally gas turbines or gas engines that burn natural gas. A few burn biogas or petroleum-derived liquids, such as diesel oil and jet fuel, but they are generally more expensive than natural gas, so their use is limited to areas not supplied with natural gas. However, many peaker plants are able to use petroleum as a backup fuel, as storing oil in tanks is easy. The thermodyna… Webb6 maj 2014 · The number of poles (magnetic poles) and the rotational speed determine the output frequency: Freq = Engine_RPM * Number_Of_Poles / 120. Typically, a United States portable generator runs at 3600 RPM, with 2 poles, for a design frequency of 60Hz. Larger portable generators run at 1800 RPM with 4 poles here. That is how frequency is …
