How to use it
Pick two chimneys and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try GRES-2 against Homer City to see the 49 m gap. The bars below scale to GRES-2 so Anaconda looks thin next to it. Switch the unit to feet for US figures. Ratios are exact divisions of the stack heights.
Mitchell at 368 ranks above Kennecott at 370 by metres in tables that list 368 over 365 variants despite draft quirks. Inco is listed at 385 with 381 in older tables. Kennecott is listed at 370 with 365 in older tables. We use 385 and 370 as primary with variants noted. Anaconda 178 is a preserved historic stack kept only for scale. Figures follow Wikipedia tallest chimneys with plant specs.
