Abstract
135,123. Takahashi, Y. May 2, 1919. Water-tube boilers; sediment collectors; feed-water, supplying and controlling.-A water-tube boiler is constructed with two upper transverse drums, one lower drum, and longitudinal tubes alternately inclined to the horizontal. The top is cased in and a feedwater heater placed between the upper drums. The latter are coupled by a common feed-water pipe, and two mud-collectors are disposed at the bottom corners. Air for the furnace is heated in tubes passing through a bottom chamber to which is by-passed some of the flue gases. From a bottom drum 7, Fig. 5, tubes 11 pass in zigzag formation between headers 9 which rest on brackets 8, the upper tubes which are more inclined passing to the twin upper drums 4, 4'. A casing 6 and flue 5 is mounted on the drums, and the sides are cased as at 3. The feed water from the heater 13 passes through a valve 18, Fig. 10, to perforated pipes 17 in the drums, thence by pipes 16 and downcomers to the mud-drums which have trap faces r, r', Fig. 4, and an outlet passage n to the end of the bottom drum 7. Each mud-drum is coupled by connexions m, m<1> with the top-drums 4, 4'. In a modification a perforated diaphragm replaces the inclined trap faces. The bottom water drum 7, Fig. 14, has a number of holes c at the side for the bottom row of tubes, and is divided by partitions f for equalising the flow; opposite the openings are handholes with inspection doors d. The headers 9 have vertically disposed pairs of holes, h, h<1>, Fig. 17, each pair being diaphragmed off and having a large inspection door d'; the header has a footpiece l which rests on the next lower header. The connexion of the top tube 11 with the drums is made through an elbow piece with flange and union connexions, the elbow being provided with a plug for cleaning. The feed-water heater consists of plain tubes s in tiers coupled to alternate headers u, Fig. 13, spacing horizontally and vertically being obtained by holders v and rods w respectively, the complete unit being supported by channel members 12 from the top drums. Beneath the bottom drum is a tunnel 20 which is supplied with waste furnace gases by pipes 19 coupled to the ends, these gases escaping by a pipe 21 at the centre to the main flue 5. Passing through the tunnel to the furnace are air-supply pipes, the supply being regulated by external shutters.
