• F01K 5/00 Plants characterised by use of means for storing steam in an alkali to increase steam pressure, e.g. of Honigmann or Koenemann type
• F01K 7/00 Steam engine plants characterised by the use of specific types of engine (F01K3/02 takes precedence); Plants or engines characterised by their use of special steam systems, cycles or processes (reciprocating-piston engines using uniflow principle F01B17/04); Control means specially adapted for such systems, cycles or processes; Use of withdrawn or exhaust steam for feed-water heating
• F01K 9/00 Plants characterised by condensers arranged or modified to co-operate with the engines (by condensers structurally combined with engines F01K11/00; steam condensers per se F28B)(F01K23/04 takes precedence)
