Boiler Feedwater Treatment (Part I): Why Water Treatment

Hydrogen gas sampling of the boiler steam is done to measure the corrosion potential of the boiler water. This test for corrosion is based on the release of hydrogen gas when iron corrodes. Measuring the amount of hydrogen gas released detects boiler water conditions and indicates if corrosion conditions exist in an operating boiler.

Scientists Making Hydrogen Efficiently from Water Steam

Trying to make hydrogen a viable fuel, economically and energetically, a team of researchers from Idaho National Laboratory splits water steam into hydrogen and oxygen using electrolysis, but from steam, and at a high temperature. They make use of a nuclear power plant, using a part of its produced electricity to make the electrolysis.

Corrosion Fatigue in Boiler Tubes - Thielsch Engineering

In the early 1980s, the Electric Power Research Institute (EPRI) identified 22 mechanisms that could result in the failure of a boiler tube. One of those mechanisms involved corrosion fatigue. At that time, this mechanism was not well understood. Moreover, there were no permanent solutions to address this mechanism. In 1992, approximately 10 years after

How Syngas and Hydrogen are Produced from Natural Gas

Steam methane reforming (SMR) accounts for about 95 percent of the industrial hydrogen produced domestically and about half the world's production. The process begins with the introduction of superheated (1,300 to 1,800 degrees Fahrenheit) steam and natural gas into an array of vertically hanging tubes filled with nickel catalyst.
