Description

F01K covers steam engine plants and power generation systems utilizing steam as the working fluid, including boiler-turbine combinations, auxiliary equipment, and thermal efficiency improvements. It encompasses steam accumulators (pressure vessels for storing thermal energy), and engine plants employing non-conventional working fluids or thermodynamic cycles not covered by other F01 subclasses, such as organic Rankine cycles or supercritical fluid systems. This classification includes complete power plant configurations, control systems, and integration of multiple components, but excludes individual components (turbines, compressors, pumps) classified elsewhere in F01 unless presented as an integrated plant system. F01K serves as a residual category for specialized or emerging engine technologies that do not fit standard internal combustion or specific turbomachinery classifications.
