It appears in Chapmans patents (1752 and 2511of 1888) and in Fosters (13284 of 1890), where the flow is defined by verticalpartitions alternately above the upper and below the lower tube plate of avertical submerged tube apparatus. Mechanical circulation as obtained by a screw propeller located belowthe lower tube plate is found in Fletchers patent (14164 of 1886), but thismeans does not seem to have come into common use. Distribution of the hquid over the heating surface in thin layers as a spray,or by other means, forms what is known as film evaporation. It appearsfirst in Clelands patent (4696, 1822), and is also shown in RilUeuxs first -S^.
