Formgewölbe twyer arch / tuyere arch Explanation: Formgewölbe: twyer arch (of a high furnace) http://books.google.com/books?id=IhsJAAAAQAAJ&pg=PA13&lpg=PA... "The number and arrangement of twyers vary very considerably. The smaller charcoal furnaces have often only two, placed on opposite sides of the hearth. Three is a more usual number, one being placed at the back ; i.e., opposite to the tymp, and the others at the sides of the hearth. "When a larger number is used, they are generally placed at equal intervals all round the hearth. This method is usually adopted in cupola furnaces ; but in South Wales, where there are many large furnaces with only three twyer arches, they are sometimes arranged in series ; thus, two will be put through each of the side open- ings, and the same number at the back, or three at the sides, and one or two at the back, &c. " http://www.ebooksread.com/authors-eng/h-hilary-bauerman/a-tr... "Twyer, twī′ėr, n. a tube through which the blast of air enters a blast-furnace.—Also Tuy′ere, Tweer, Tuy′er, Twi′er. [Fr. tuyère, a nozzle.]" http://en.wikisource.org/wiki/Chambers's_Twentieth_Cent... "Tuyere arch: An arch in a blast furnace to admit a tuyere. See also: tuyere" http://www.websters-online-dictionary.org/definition/Tuyere ... -------------------------------------------------- Note added at 1 hr (2012-05-08 16:59:07 GMT) -------------------------------------------------- Another context example both for tymp arch and for tuyere arches http://mht.maryland.gov/nr/NRDetail.aspx?HDID=175&FROM=NRMap... |
