Abstract
In the present work, a coal-fired magnetohydrodynamics (MHD) power plant is analyzed to predict its performance using constant nozzle inlet Mach number. Two supersonic nozzles, namely, A and B are taken with the variation in throat to exit area ratio. The nozzle exit parameters, adiabatic flame temperature for coal combustion, and the performance parameters of the segmented Faraday-type MHD generator are calculated using each nozzle separately. It has been found that an increase/decrease in nozzle–area ratio resulted in an increase/decrease in gas velocity at MHD generator inlet but with a reduction in temperature. The nozzle efficiency is found to be almost independent of either the area ratio or Mach number at nozzle exit. The maximum voltage and power are found to increase with increase in area ratio. The nozzle exit velocity and efficiencies are found to vary with area ratio.
