Method of generating stable fogs

Abstract

Abstract DISCLOSED HEREIN IS A METHOD OF GENERATING STABLE WATER MISTS OR "FOGS" PARTICULARLY USEFUL IN REDUCING THE RISK OF FROST DAMAGE TO GROWING CROPS. STEAM, OR PREFERABLY A GASEOUS MIXTURE OF STEAM AND COMBUSTION GASES IS PASSED THROUGH A LIQUID LAYER OF AN EVAPORATION RETARDING CHEMICAL SUCH AS N-HEXACECANOL. AT THE TEMPERATURE OF THE GASEOUS MIXTURE A QUANTITY OF THE EVAPORATION RETARDING CHEMCIAL IS VAPORIZED PROPORTIONAL TO ITS VAPOR PRESSURE AT THAT TEMPERATURE. THE GASEOUS MIXTURE OF STEAM AND CHEMICAL VAPORS OR STEAM, COMBUSTION GASES AND CHEMICAL VAPORS PASS UPWARD INTO THE ATMOSPHERE WHERE THE STEAM AND CHEMICAL VAPORS CONDENSE TOGETHER AT SUBSTANTIALLY THE SAME TIME AND IN SUBSTANTIALLY THE SAME PROPORTIONS AT WHICH THEY WERE EVAPORTATED, THE EVAPORATION RETARDING CHEMICAL FORMING A SATURATED MONOLAYER AROUND THE SURFACE OF EACH OF THE CONDENSED WATER DROPLETS. THE COMBUSTION GASES, BEING NONCONDENSABLE AT THE ATMOSPHERIC AMBIENT TEMPERATURE, PASS INTO THE ATMOSPHERE. PREFERABLY, STEAM IS GENERATED BY BURNING AN AIR-FUEL MIXTURE IN CLOSE PROXIMITY TO A BODY OF WATER AND EJECTING THE HOT GASES, PRINCIPALLY CARBON DIOXIDE AND NITROGEN, DIRECTLY INTO THE WATER TO HEAT THE SAME AND GENERATE STEAM.
