At the current technology we need high temperature on the heat transfer liquids. This high
temperature can be obtained by high pressure hot water, saturated and superheated boilers.
But due to hot oil can be obtained and used whitout pressure.
For obtaining of saturated steam and superheated water 250-350 C temparature with 40 bar up
to 90 bar pressure is needed. On the other hand to obtain of 300 C hot oil we need only under
the 3 bars for the pressure of pipeline and boiler.
On the otherhand cause of corrosion and calcity that occures erosion and erode we need in the
pipe of boilers and equipments are will be pay its cost. |
