Combustion Engineering

Combustion Engineering (C-E) was a multi-national American-based engineering firm and a leader in the development of both fossil and nuclear steam supply power systems in the United States with approximately 42,000[10] employees worldwide. Originally headquartered in New York City, C-E moved its corporate offices to Stamford, Connecticut in 1973. C-E owned over three dozen other companies including Lummus Company, National Tank Company and the Morgan Door Company. Former workers have gone on to hold leadership positions in major engineering firms and governments around the world. The company was acquired by Asea Brown Boveri in early 1990. The boiler and fossil fuel businesses were purchased by Alstom in 2000, and the nuclear business was purchased by Westinghouse Electric Company also in 2000.

Combustion Engineering was organized in 1912 through the merger of the Grieve Grate Company and the American Stoker Company, two well-known manufacturers of fuel burning equipment. The company was originally headquartered on 11 Broadway and at 43 - 5 - 7 Broad Street (Manhattan), both in Lower Manhattan. The city block was leased from the Alliance Realty Company in April 1920. In May of the same year the firm began construction of an eight story office building on the same site.

During the 1920s, C-E's signature boiler equipment was the English designed Type-E stoker. C-E also offered several other types of underfeed stokers in addition to the Type-E. During the 1920s, all of C-E's stokers were fabricated in manufacturing plants along the Monongahela River south of Pittsburgh.

In 1925 C-E entered the steam boiler business, beginning with a steam boiler installed at the Ford Motor Company's River Rouge Plant in Dearborn, MI. C-E also acquired two boiler companies in Chattanooga, TN to augment its manufacturing capabilities.
