Abstract
The plasma-chemical technique for intensification of combustion is based on the interaction of a jet of low-temperature air plasma and the fuel. In order to determine the principal characteristics of a combustor operation process having a plasma-chemical element, an appropriate mathematical model has been used. Interphase interaction is taken into account by considering the drops of liquid as the sources of mass, impulse and heat for the gaseous phase. Simulation of plasma-chemical intensification processes is carried out through solving the equation of fuel concentration conservation in which the rate of its variation is expressed through the value of the resulting reaction of activation energy. Plasma-chemical action raises the efficiency of fuel combustion under idle running and partial loads conditions up to 3-9% as shown by experimental data obtained during the tests of a marine gas turbine combustor operating on distillate liquid fuel. The emission of carbon oxide during plasma-chemical reactor operation drops by a factor of 1.2- 1.6 depending on the amount of plasma-chemical products added.
