Construction of a cooled container is presented with a detachable loading vessel and a sealed heat exchange
cavity. With the aim of increasing the endurance of the end sealing under high temperature conditions and re
ducing air flow through the container the end seal it is made in the form of a circular collector with a steam
generator with circular orifice, that is directed at an angle to the wall of the pipeline and in a direction opposite
to container movement.
Keywords: transportation, pipeline, hot load, cooled container, sealed heat exchange cavity.
Previously [1 – 3] a device and methods for moving hot
loads due to their heat have been proposed. Possible fields of
application were demonstrated for container pipeline trans-
portation in Russian enterprises. In order to introduce the lat-
ter and use more completely the energy of a hot load, a con-
tainer is proposed  with a sealed heat exchange cavity.
The container (Fig. 1) comprises a vessel 1 for the hot
load and a water jacket 2, that through a cut-out 3 in the
lower of a partition 4 communicates with a sealed covered
vessel 5. In the upper part of water jacket 2 above the water
level there is an inlet connecting pipe 6 of a heat exchanger 7
for extraction of saturated steam. With the aim of cleaning
the steam, entering the exchanger, from water droplets, in the
zone of inlet pipe 6 installation there is a baffle 8 and the wa
ter jacket 2 is made with an expander 9. The outlet pipe 10
emerges beyond the limits of a gasket 11 of the container into
pipeline 12. In the outlet pipe 10 of the heat exchanger 7
there is a valve 13 adjusted to the design pressure in the pipe
line. In order to create sealing of the steam generation system
there is a valve 14 built into the hermetically covered vessel.
The loading section of vessel 5 is filled with water and
closed by valve 14. Then the vessel is charged with a hot
load. During heat exchange of the hot load with water steam
release commences within the water jacket. Replenishment
of the water jacket occurs through the lower cut-out 3 of par
tition 4. Presence of this partition leads to ordered flow of the
replenishing water, due to which steam release is intensified,
forming a steam-water mixture that enters into the expansion
9 of the water jacket 2.
Within expansion 9, due to a reduction in the rate of as-
cent of steam bubbles and also the velocity of the team-water
mixture above the surface of the water, there is separation of
steam from coarse water droplets. Fine water droplets are
separated from the steam as a result of inertial forces that
arise with flow of the water-steam mixture around baffle 8
installed in front of the inlet pipe 6. Saturated steam cleaned
from water droplets enters the heat exchanger 7 through inlet
pipe 6, where it is superheated. From the heat exchanger
superheated steam is discharged by valve 13 into the closed
cavity behind the gasket 11 of the container at a prescribed
pressure and it is accumulated within it. On reaching the re
quired pressure in the accelerating section of the pipeline the
container is set into motion. Due to installation of the inlet
pipe above the water surface of the water jacket 2 the overall
system of steam generation is divided into two: preparation
of saturated steam and preparation of superheated steam.
Here the considerable part of the heat of the transportable
load gives the heat exchanger a considerable part of the heat,
i.e. the process of steam superheating. Superheated (dry)
steam, entering the pipeline, behaves as compressed air, i.e.
its elastic force is reduced until it is cooled to the saturation
temperature. Heat transfer from the superheated steam is
very insignificant, and therefore the considerable elastic
forces of steam are maintained for a longer time than with
use of saturated steam. This leads to an increase in the con
tainer transportation rate. The intensity of steam preparation
is mainly determined by rational use of the heat exchange
