Abstract
128,849. Weir, G. & J., and Lang, C. R. Dec. 20, 1918. Feed-water, supplying and controlling. - Relates to feed-water systems of the kind described in Specifications 125,149 and 126,014, and comprising a condenser a, condensate pump c, air ejector g, surface feed-heater m, feed-tank t, and a feed-pump r<1>. The invention consists in controlling the rate of discharge of the feed pump in accordance with the level in the feed-tank t in order to prevent the emptying of the feed-tank and the consequent access of air to the system. For this purpose a float 11 is provided in the feed-tank together with link-work or other means for actuating a throttling-device 17 in the discharge pipe of the pump or for controlling the supply of motive fluid to the motor driving the pump. Where a number of feed pumps are used together, the centrifugal pumps are controlled by throtting the discharge, and the direct-acting steam driven pumps by controlling the motive fluid. Instead of providing a return pipe 8 leading from the feed-tank to the condenser, as described in the above-mentioned Specifications, the return pipe 8 may be led from the main feed pipe f on the discharge side of the secondary feed-heater q.
