<p>Field of the invention: warming-up and subsequent tank unloading from hardened viscous material, mainly viscous oil and mineral oil products during the cold seasons of year. The essence of the invention: In the method steam is submitted in through nozzles of submersible heater, before warming-up actual temperature of the hardened material is measuring, and its warming-up is carried out in two stages divided among themselves by a technological pause at which steam submission is absent, at the first stage of warming-up a gain of temperature of the hardened material is provided, and duration of said technological pause is determined depending on results of measurement of variable depth of a mirror of a bath of rests of loaded material, and also from results of measurement of variable height of nozzles arrangement of said submersible heater concerning said mirror of a bath of rests of loaded material, breaking said technological pause in steam submission at negative result of values of measurements difference of depth of said mirror of a bath of rests of loaded material and height of an arrangement of said nozzles of said submersible heater concerning this mirror. In the device for warming-up a viscous material in the tank, mainly oil and mineral oil, comprising the first independent duct for submission of heat-carrier, pneumatically connected with jet devices directed in parallel to a mirror of said material in the tank and executed as hollow vertical bar, the second independent duct for submission of the heat-carrier, located in parallel to said first independent duct and near to it and pneumatically connected with face nozzles directed to a bottom of the tank , and also means for overlapping of the heat-carrier submission.</p> |
