Summary:
The Emmet Mercury Boiler Records contains information about General Electric Company and Hartford Electric Light Company's development, installation, and use of William Le Roy Emmet's mercury boiler units. The mercury boiler units used mercury fluid along with steam power to improve cycle efficiency in converting coal or oil to electric power. The collection contains articles, news clippings, reports, instruction manuals, log books, data sheets, photographs, and drawings related to the experimental unit installed at Dutch Point, Connecticut, and the first commercial use of a mercury boiler at the South Meadow Station in Hartford, Connecticut.
Scope and Contents:
The collection documents the construction, operation, and demolition of mercury boiler generating units developed by William Le Roy Emmet and installed by the Hartford Electric Light Company in Hartford, Connecticut. The collection contains articles and research about the use of mercury and the development and implementation of mercury boilers. Also included is general correspondence between Hartford Electric Light Company and General Electric Company, operational logs, collected data, instructional guides, inspection reports, and photographs and drawings for the Dutch Point Mercury Boiler and the South Meadow Station.
Arrangement:
The collection is arranged into four series.

Series 1: Background and Research on Mercury Boilers, 1920-1961

Series 2: Correspondence, 1921-1950

Series 3: Dutch Point Mercury Boiler Operational Records, 1923-1949

Subseries 3.1: Data Sheets and Reports, 1923-1927

Subseries 3.2: Log Books and Instructions, 1924-1949

Subseries 4.2: Log Books and Instructions, 1928-1955

Subseires 4.3: Photographs and Drawings, 1928,1955
Historical:
The mercury boiler was developed by a General Electric Company's engineer, William Le Roy Emmet, to use mercury fluid in conjunction with steam power to improve cycle efficiency in converting coal or oil to electric power. An experimental mercury-steam generating unit was installed by Hartford Electric Light Company in 1923 at Dutch Point, Connecticut. In June 1927, ground was broken for the South Meadow Station in Hartford, Connecticut, and Babcock and Wilcox Company was contracted for the boiler. This unit was the first commercial installation in the nation and was based on the data collected from the Dutch Point unit. The Dutch Point unit was damaged during the course of operations and was permanently shut down by Emmet in September 1927. Emmet requested that all efforts be focused on the South Meadow Station. In August 1947, the first commercial unit at South Meadow Station was taken out of service and disposed of, and a second unit was installed and put into use on January 1, 1949. The engineering company, Foster Wheeler, was used to help design the second unit. During inspections in 1959 and 1960, it was discovered that the second unit had a wastage issue, and the unit was then operated at half load capacity for the remainder of 1960. On January 4, 1961, the second unit was removed from operation, and on April 19, 1961 it was officially retired. The mercury was removed and sold to Woodbridge Chemical Corporation. The decision was made to not to replace it with another mercury unit.
