• F22B 29/02 of forced-circulation type
• F22B 29/04 of combined-circulation type, i.e. in which convection circulation due to the difference in specific gravity between cold and hot water is promoted by additional measures, e.g. by injecting pressure-water temporarily
• F22B 29/06 of once-through type, i.e. built-up from tubes receiving water at one end and delivering superheated steam at the other end of the tubes
