4.2.16. Heating Line
There is heating line for heating the ma-
terial carried in STC tankers. Heating op-
eration is performed by 2 different
methods, namely by steam and liquid.
Heating by Steam
•
Hose line that shall provide the hot
steam to the system shall be con-
nected to the heating line inlet line
(1).
•
Hose line that shall be used for dis-
charging the steam in the system
shall be connected to the heating
line outlet (2).
•
Bring the ball valve (3) to closed po-
sition and perform the heating oper-
ation by supplying hot steam to the
system.
•
Heating line is designed for a pres-
sure of 7 bars maximum. Safety
valve on the line (4) prevents the
pressure on the system from ex-
ceeding 7 bars.
•
Also, system pressure may be ob-
served with t he pressure gauge (5)
on the heating line.
Heating line
Heating by liquid
Closed circuit heating system is used for
heating with hot water.
Heater and the pump are usually placed
inside the heater cabinet (6) on the left
side of the tanker. The fuel tank (7) that
provides the fuel requirement of the
heater is located on the cabinet.
