EN: The results of the experimental-industrial tests of the fuel burning pulsating resonance system at the posts of drying and heating of steel-teeming ladles are given in the paper. The high performance and efficiency of the system were established. Reduction of the natural gas saving was 2.7 ÷ 26.1% when ladles drying, and 19.5 ÷ 37.8% when heating.
