METHOD OF PRODUCING WORKING MEDIUM FOR HEAT ENGINES Russian patent published in 2004 - IPC

FIELD: mechanical engineering; heat engines.

SUBSTANCE: proposed method includes delivery of condensed cosoluble mixture of oxidizer with combustion materials into reactor preliminarily heat to 300^oC. Use is made of solutions of ammonium nitrate with cosoluble organic and inorganic fuels. Content of solvent in solution is within 5 and 60% (by mass) at content of all fuel components within the limits from stoichiometric amount to 60% (by mass) with use of formed gas-gas mixture of products as working medium in heat engine plants. Gas decomposition products of initial water-nitrate solution enriched by fuel over stoichiometric amount are after-burned in portions of compressed air according to operating cycle of air-fuel internal combustion engines. Gas decomposition products of initial water-nitrate solution enriched by fuel over stoichiometric amount, after execution of useful work in engine plant are after-burned in atmospheric air with transmission of generated heat energy to working medium before engine plant.

EFFECT: enforced power of plant, reduced toxicity of exhaust gases, maximum temperature of cycle and temperature of exhaust gases.
