Abstract: A simulation system for a fossil fuel power plant simulator. The simulation system includes first, second, and third displaying means for respectively displaying selected simulated flame characteristics within the furnace, emission density images from the smokestack, and water/steam levels as indicated by a steam drum level indicator of the power plant. A computer correlates the images displayed on the first, second, and third displaying means such that a change in the operating level of the power plant causes corresponding changes in the simulated flame characteristics, emission density images, and water/steam level.
