The principle of fluidisation is the result of solid particles being supported by the dynamic effect of a stream of gas, usually air. There are two main techniques for operating solid-fired fluid beds: the slagging type (as in the Ignafluid furnace) and the non-slagging type. The temperature of the bed determines which category applies, the slagging type operates at approximately above 1,000 deg C. The factors affecting the choice of steam cycle in marine applications are discussed together with their effect on boiler design. Very high steam temperature are limited by available materials for superheater tubes. The most recent application, although not a fired installation, is in the Fjordshell which has successfully undergone trials producing 3855 kg/h of steam at 14 bar from the exhaust gas of a 12,000 shp Sulzer Diesel engine.
