Method of measuring moisture in a burnable absorber

摘要

Disclosed is an apparatus for measuring the moisture content of a sample. The apparatus includes a first sealed chamber for accepting the sample and a first impulse furnace within the first chamber for dissociating water in the sample into the hydrogen and oxygen, a second sealed chamber in gaseous communication with the first chamber, a second impulse furnace within the second chamber for dissociating water and the hydrogen and the oxygen, and a hydrogen analyzer for determining the amount of hydrogen formed by the first and second impulse furnace. Also disclosed is a method of measuring the amount of water in the sample. The sample is heated in an enclosed chamber in the presence of a water dissociation catalyst, whereby water in the first chamber is dissociated into hydrogen and oxygen. Vapors are passed from the enclosed chamber to a second enclosed chamber which contains a water dissociation catalyst, whereby water in the vapors is dissociated into hydrogen and oxygen. The vapors from the second chamber are then analyzed to determine their hydrogen content.
