This paper describes the chemical equilibrium composition of gas plasma with addition of alkali metals as ionization seeds, calculation methods and results of the equilibrium and “frozen” thermal and electrical properties. In the calculation of the 23 kinds of ingredients, 20 kinds of thermoelectric properties. The effects of these properties on the characteristics of a magnetoelectric generator are also discussed. Calculated conditions and ranges are: Burner: Diesel. Oxidant: oxygen-enriched air, wherein the oxygen weight ratio φ = 0.2315 (air) -1.0 (pure oxygen). Oxygen coefficient α_Σ: 0.7-1.1 oxidant preheating temperature T_p: from normal temperature -2000K. Seed potassium carbonate solution concentration m: (?) From 0.5-1.0 (dry powder). Gas containing potassium rate ε: from 0.01-0.03 (weight ratio). Pressure p: from 0.6-8.0 kg / cm ~ 2. Temperature T: from 2000K - adiabatic combustion temperature, step 100K Magnetic induction B: 2 or 5 Weber / m ~ 2. The results have been applied to the design, theoretical analysis and plasma diagnosis of MRF.
