January 1973 ANTI-CORROSION 21 One of the most compact deaerators on the market for producing non-corrosive boiler feed water has been intro duced by Neckar Water Engineering Ltd. A feature of the design is the introduction of a steam lift pump, based on the principle of an air lift. Th e initial unit, which has been proved in operational use, has a capacity of 10 tons of water per hour, but designs for units of up to 200 tons capacity are currently being de veloped. The quality of deaerated water produced is guaranteed to be below 0·005 mg of oxygen (O ) per litre. Th e design differs markedly from that of conventional types, in that the scrubbing compartment is incorporated inside the main vessel. This results in a more compact and lighter unit, which reduces installation and erection costs. The 10-ton capacity unit is basically a horizontal cylinder, five feet in diameter and nine feet long, which has some 30% less surface area to lag than conventional designs, with consequent re duced heat loss. Raw make-up water enters at one end of the deaerator as I n operation, the deaerator has the additional advantage of a fine, atomised spray, before falling over a baffle distribution being quickly brought into use from cold. The storage com system into the feed compartment. A steam lift pump, which partment being emptied, the heating steam can start to treat operates on the same principle as an air lift pump, draws the the incoming make-up within a few minutes. Standard controls water from the feed compartment and lifts it into the storage fitted include a proportional water make-up in the feed com compartment, from which it is passed to the boiler by a partment to control the flow of raw feed water, and a pressure conventional feed pump. I n addition to operating the lift pump, regulator governing the rate of steam inlet. the steam also heats the feed and assists in scrubbing it free Neckar Water Engineering Ltd., 31-33 College Road, of oxygen, CO , etc. Harrow, Middlx.
