Abstract
208,158. Bell, J. E. July 1, 1922, [Convention date]. Feed - water, heating. - In a boiler feed-water heater having banks of horizontal tubes through which the water flows downwards, and over which the hot gases flow upwards, the number of tube paths is such that the velocity of the water flow during the normal operation of the boiler is above that which permits of the equalization of the water temperature throughout the heater by convection. The tubes D<1> of a feed-heater placed in a flue above a water-tube boiler are arranged in staggered rows, and are connected to junction boxes D" and supported at their centres by a plate D<5>. By altering the tube connections, the velocity of water flow is so determined as to give a definite graduation of temperature increasing towards the bottom of the heater. Internal corrosion is thus confined to two or three rows of tubes in which the water is at about 180‹. A vertical flue passage D<12> between the tubes is fitted with dampers E, which are opened to allow part of the gases to pass directly to the fan casing H when the load on the boiler is high. The casing around the heater is packed with heat insulating material. Castiron rings are shrunk on the heater tubes. In a modification, two vertical banks of tubes connected to a common header are arranged in parallel flues so connected that the hot gases pass upwardly through one bank and downwardly through the other bank. Specifications 14868/96 and 22663/03, [both in Class 123, Steam generators], 24162/14 and 200,060 are referred to.
