Abstract
Some embodiments provide engines comprising: a fuel line; a gas combustion system; a first power turbine positioned within an exhaust gas stream and configured to operate at a first rotation speed; a second power turbine downstream from the first power turbine, and configured to operate at a second rotation speed that is less than the first rotation speed; and a heat exchanger configured to receive the exhaust gas stream, wherein a portion of a fuel line is positioned to receive heat from the heat exchanger configured to heat the fuel; a gear ratio (GR) is defined by a ratio of the second rotation speed to the first rotation speed; a combination of the first power turbine and the second power turbine includes a number of blade rows (NBR); and a system effectiveness control (SEC) is established as a function of the GR and the NBR.
