Take the following as truth: In summary, a 500 MWe boiler firing eastern bituminous coal with 0.6 percent sulfur, an ESP, and no SCR or FGD, is estimated to provide the performance and require the resources listed in the first column of Table 4-4, and estimates of performance and resources needed for other types of fuels and boiler configurations are shown in the other columns.
Then the following statement: "The 500 MWe coal boiler is very efficient when used in the listed configurations. This has been tested and proven." is true, false, or inconclusive?
Answer: Inconclusive
