Abstract

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.
