CUTTING SHIPS' FUEL COSTS

The Hitachi-led effort has produced a system which combines a new diesel engine, turbo-generator and steering system. The Anglo-Swedish combine is collaborating on the problems of applying fluid-bed combustion to low-grade oils for ship propulsion. Hitachi Zosen reckons that the complete system will help to reduce total fuel costs by 20 to 30 percent. Babcock and Wilcox and Stal-Laval Turbin are collaborating on the problems of applying fluid-bed combustion of low-grade oils to ship propulsion. In the fluid-bed system, blow-power lifts and agitates a bed of granular material -- for example, sand -- so that it behaves like a fluid on contact with the fuel injected into it. The constant movement creates conditions for almost ideal combustion, for much better heat transfer pipes submerged in the bed, and, in the case of ship propulsion, is attractive in that it cuts corrosion of the steam-raising pipework.
