Compact transportable complex of technological equipment for cleaning (heating up and removal of residues) of boilers of railway

The proposed technology and equipment are designed for removal of particularly complex residues of highly viscous oil products from the boilers of tank wagons.
The technology is based on a circulating method based on erosion and removal of frozen high-viscosity oil products, including bitumen, heated to a sufficient and necessary temperature with fuel oil. The proposed technology and equipment are protected by patents of the Russian Federation.
The proposed method in comparison with steaming technologies has a number of advantages:
- due to intensive heat exchange between the mass of heated fuel oil supplied and frozen oil product in the tank provides high speed of this technological process;
- watering of oil products is excluded and there is a possibility of their further marketable use;
- due to lower temperatures than those used in steaming technology, the possibility of local overheating and, as a consequence, coking of oil products in the boiler of the tank car is excluded.
