THE HUMID COMBUSTION TO PROTECT ENVIRONMENT AND TO SAVE THE FUEL: THE WATER VAPOR PUMP AND MAISOTSENKO CYCLES EXAMPLES

Remi Guillet

Краткое описание

In the past, water has been used as an anti-knock agent or as an "additive" component to improve combustion efficiency, and to boost the engine. Today, added water can also serve both environmental and energy savings goals. Early in the 1980s a thermodynamic cycle, called the "water vapor pump cycle" (WVP-cycle) was invented. Thanks to this cycle, the useful recovery of heat coming from the condensation of flue gases was applied towards new kinds of heat plants using fuels like the natural gases. By developing the WVP-cycle, and besides the analysis of its energy savings efficiency, we also discovered the correlative reduction of NOx formation, and also discovered the efficiency of humidity transfer between two gas flows. At the same time, other kinds of "humid combustion" were developed, notedly with gas turbines running the "STIG-cycle" and "HAT-cycle," and more recently the "Maisotsenko-cycle" has been described. This paper points out the specific advantages of humid combustion and reminds us what we have learned about the limits of this practice thanks to the WVP-cycle development. Finally, we indicate some useful future developments to fully benefit from the potential offered by humid combustion, in WVP-cycle, in gas turbines running "humid" cycles.
