FIELD: process engineering.
SUBSTANCE: invention relates to equipment intended for circulation hearing and draining of high-viscosity and congealed products from tank cars at lo temperatures when draining without preheating is hindered possible at all. Proposed nozzle comprises cylindrical case 1 with nozzles 3 arranged along circumference and thrust made on the face of case 1 to allow nozzle outlets to stay not lower than tank car drain valve outlet with hydromonitor complete lifted to thrust against the plate of completely opened drain valve. Case 1 has holes on the side opposite the said face with said thrust to allow fluid to flow at 60 degrees and less to case axis.
EFFECT: feed of hot product into tank car cold product intake zone to allow said product to flow in suction pipeline.
