Emil Biederman (c1833-1897)
1891 Living at 32 The Grove, Lambeth: Emil Biederman (age 58 born Switzerland), Civil Engineer. With his wife Edith Biederman (age 43 born Lambeth) and their five children; Amy Biederman (age 28 born Chelsea); Helen Biederman (age 27 born Chelsea); Clara Biederman (age 25 born Chelsea); Emil Biederman (age 6 born Lambeth); and Edith Biederman (age 5 born Lambeth). Two servants.
Late 19th century: Mr. E. Biederman and Mr. E. W. Harvey designed a new form of Siemens furnace arranged to recover waste gases as well as waste heat.
According to this invention, a certain proportion of the waste products of combustion are supplied hot into the incandescent fuel of the gas-producer, and the carbonic anhydride of these waste products is thus converted into carbonic oxide, by which a considerable economy in fuel is realised. The gas-producer in the new form of Siemens furnace partly takes the place of the gas regenerator in the original Siemens furnace, so that the new form permits of the suppression of the gas regenerators, the placing of the gas-producer close to the furnace, and a simplification and economy in construction.
