<p>The present invention relates to jet blowing techniques and is characterized in that, after the required pressure value of a gas medium at the input of a jet blower is obtained, the ratio value of the feeding pressure of the liquid medium in the jet blower nozzle to the pressure value at the output of said apparatus is reduced, down to a level at which the pressure of the gas medium at its entry into the jet blower increases in stages. Thereafter, the ratio value between said pressures is set and the ratio of feeding pressure of the liquid medium in the jet blower nozzle to the pressure value at the ouput of said apparatus is established at an upper level as compared to the set ratio, resulting in saving work by in the liquid-gas jet blower.</p> |
