That version of the story goes something like this: On July 1, 1937, Amelia Earhart and her navigator Fred Noonan departed from Lae, New Guinea in Earhartâs Lockheed Electra 10, on what was to be the longest portion of Earhartâs highly publicized round-the-world flight.
Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler. Burning in suspension, the coal/air mixture provides the most complete combustion and maximum heat possible.
âWe found a way to release the heat from coal without burning.â The process removes 99 percent of the pollution from coal, which some scientists link to global warming. Coal-burning power plants produced about one-third of the nationâs carbon dioxide total in 2010, or about 2.3 billion metric tons, according to the Environmental Protection Agency (EPA).
