CONVERSION METHOD OF HEAT ENERGY TO MECHANICAL ENERGY, METHOD FOR INCREASING ENTHALPY AND COMPRESSION COEFFICIENT OF WATER VAPOUR Russian patent published in 2012 - IPC F01K25/06 

FIELD: power industry.

SUBSTANCE: conversion method of energy to mechanical operation and method for increasing the enthalpy and compressibility factor of water vapour involves connection of working liquid contained in vessel, heat energy. Vaporous working liquid is condensed and cyclically returned as liquid phase to the vessel. To working liquid (prior to and after the beginning of heating process) there added is catalytic additive in the form of catalytic substance or catalytic mixture of substances in quantity of 0.0000001 to 0.1 wt %. Additive represents solid substance, its solution or suspension, or liquid substance or its emulsion. Catalytic substance and mass ratio of individual substances in catalytic mixture is chosen so that it prevents decomposition of substance or mixture under action of high temperature and pressure in compliance with existing need and workshop conditions.

EFFECT: invention allows increasing the efficiency of the target process, enlarging operating capabilities at economic attraction of available and safe processes.
