The utility model relates to oil heaters with an intermediate heat carrier and can be used to heat oil and complex oil emulsions during their transportation and field preparation.

Known heaters of oil, complex oil emulsions, gases, liquids [copyright certificates of the invention SU: No. 1744406, No. 377604, utility model patents RU: No. 42998, No. 37988, No. 43,057, invention patents RU: No. 2182679, No. 2219218, No. 2182679]. All of them are characterized by the presence of chimneys, a housing filled with an intermediate coolant, in which a heat pipe and a grocery tubular coil are installed.

Known tubular heater [patent RU: No. 2224005] containing a metal insulated casing in the form of a polygonal horizontal prism, inside of which is placed a food coil along the walls and a firebox with burner devices, the casing is made with one outlet that is connected to the chimney, Moreover, it additionally contains a second chimney and a box chimney with two couplings at the ends.

Also known is a tubular heater [patent RU No. 2256846], which comprises a housing with a grease tube placed therein, a heat exchange element in the form of a series of tubes, straight sections of which are parallel to the longitudinal axis of the housing, an intermediate heat transfer medium, a gas rotation chamber, and located on the side opposite to the chamber a burner, a chimney, a convection chamber and a jacket around the flame tube, in which an intermediate coolant is placed. The heat exchange element is made in the form of a food coil, consisting of two sections connected in series, the pipes of which are oriented around the central longitudinal axis of the housing, one section of the food coil placed in the jacket of the heat pipe, and the second in the convection chamber formed by the space between the jacket and the inner wall of the housing .

The closest analogue to the claimed utility model is a heater for liquid and gaseous media [utility model patent RU No. 43056], comprising a housing filled with a liquid intermediate coolant, and at least a food coil, a heat pipe connected to the burner device located inside the housing , and one chimney, while above the flame tube along its entire length two guide plates are installed obliquely to each other, the angle between the guide plates being 120-150 °,

The disadvantage of the closest analogue is the lack of efficiency due to not using all the features of the heat transfer process.

The objective of the claimed utility model is to increase the level of fire safety without lowering the thermal characteristics.

The essence of the utility model lies in the fact that the oil and oil mixture heater has a horizontally elongated cylindrical body filled with an intermediate coolant, in the medium of which there is a combustion chamber attached to the body with a flange, and at least one grocery tubular coil located in it in the form of a series of sections offset from each other, a burner, a chimney and an expansion tank, while the pipes of the food coil are tightly laid in each of the sections as two an exit spiral in the form of a series of horizontally elongated parallel pipe sections in the direction of the heater extension with curved pipe sections at the points of rotation and transition from level to level, the combustion chamber being U-shaped, into which transverse transfer pipes are welded so that they form a spiral inside the furnace spaces conducive to turbolization (swirling) of flue gas streams in order to intensify heat transfer and the most complete use of combustion energy in convective heat transfer, for lower of aerodynamic drag, the U-shaped transition of the radio - convective chamber into the convective one is made using several sectors forming a smooth rotation.

The technical result of the claimed utility model.

The solution to the problem of increasing fire safety without lowering the thermal characteristics is expressed by such technical results as welding of transverse pipes to intensify heat transfer and turbulence of the flue gas stream, which form a spiral inside the furnace space, to reduce aerodynamic drags, the U-shaped transition of the radiation-convection chamber into the convection chamber is made with using several sectors forming a smooth turn.

The claimed utility model is illustrated with the help of figure 1, 2 which shows: figure 1 is a longitudinal section of an oil heater, where positions 1-13 indicate:

1 - grocery coil;

2 - combustion chamber;

The heater of oil, oil emulsion and complex oil emulsions is made in the form of a horizontally located housing 11, filled with an intermediate coolant. An expander 3 is welded to the upper part of the casing, equipped with a fitting for filling the coolant 5 and a breathing valve 4. The combustion chamber 2 is located in the lower part of the casing 11 and has a U-shape. To intensify heat transfer and increase the heating surface, transverse transfer pipes 9 are installed in the combustion chamber 2. A burner device 7 is installed on one of the flanges 8 of the combustion chamber 2, and a pipe for removing flue gases 6. A food coil 1 is located above the combustion chamber 2, which is made in the form of a package of interconnected sections, which are two-way flat spirals that allow the most efficient use of the useful volume of the housing 11, placing in it a food coil 1 with the largest erhnostyu heat. The furnace chamber 2 and the food coil 1 are attached to the housing 11 by means of flanges 8. On the rollers 10 installed in the housing 11 of the heating unit, the combustion chamber 2 and the food coil 1 freely roll out. What makes heaters as accessible as possible for inspection and maintenance.

Heater of oil, oil emulsion and complex oil emulsions works as follows.

Oil from the oilfield network through the fitting for filling the coolant 5 enters the food coil 1 of the heater, is heated from the intermediate coolant, and then is removed from the heater. Fuel is burned in the combustion chamber 2 of the heater, transferring heat to the intermediate coolant. Cooled combustion products using a chimney 6 are removed from the combustion chamber 2 of the heater to the atmosphere. The heating unit is designed to transfer heat from the combustion products to the heated product.
