FIELD: railway transport; emptying of railway tanks and other reservoirs from oil and oil products. SUBSTANCE: according to proposed method thickened products in reservoir are heated in electromagnetic field. Heating is carried out by directed electromagnetic HF radiation within the range of 400-3000 MHz. Device has microwave oscillator 1 connected by transmission line 2 with radiator 3. Electromagnetic shield 6 is installed on neck 4 of reservoir 5. Transmission line 2 in form of metal waveguide is installed in port 7 of shield 6. Radiator 3 is made in form of directional antenna installed at angle relative to product surface. EFFECT: facilitated draining of products. 2 cl, 1 dwg
