Thermal Oil Heater use thermo-oil as heat source, that is to
say, we heat the thermo-oil in boiler first and deliver it to
heat exchanger with high-pressure pump. After releasing heat,
thermo-oil will be returned to the boiler to be reheated. The
nature of thermo-oil is different from water; though the
saturated temperature is low, it still obtains the
high-temperature thermal energy. Because the pressure of TDH
is lower than of steam boiler, it is the best consideration
for high temperature environment. |

• Excellent
thermal oil heating system
We particularly
cite the construction and principle of heat-absorbing disc and
successfully use it in thermal oil boiler. While the thermal
oil flows into the boiler, the remaining temperature from
flame preheats it first, after that, thermal oil absorbs
higher temperature from the burning flame indirectly by
heat-absorbing disc; finally, the thermo-oil will be heated by
burning flame directly. For the excellent design of the disc,
the circulating speed of thermo-oil is suitable and its
pressure drop is very low. Therefore the boiler never clogs
with thermo-oil so as not to overheat the thermo-oil and
lengthen its life.
• High capacity of
expansion tank
Under test
situation, all thermal oil flow through the expansion tank so
that the bubbles in the tank and the remaining air can be
removed fully within short term.
• Regional temperature control and circulating pump system
For this system,
most of the component parts are imported from Germany and we
assemble it with our abundant technology and experiences. The
system is designed for stability of temperature so that the
thermal energy among all regions can be used in full.

• Safety and
perfect design for boiler construction
The boiler adopts
import seamless carbon steel tubes and we design the pipe
system as a flexible construction in order to adapt to the
different temperature change. Heat-absorbing disc can rise the
burning efficiency and reduce the exhaust temperature from
chimney. With the mobile front cover of boiler and the flame
sight hole, the burning status can be visualized so that it is
easy to regulate a wonderful burning efficiency for burner.
And with automatic control system, customers can operate the
boiler more easily and more safely.
• Less noise and high efficient circulating pump
The boiler adopts
high efficient circulating pump from Germany. The circulating
pump, motor and coupling are regulated and corrected exactly
by computer. Besides, the flexible tubes are installed at the
end of inlet and outlet, and the pipe system adopts the stop
valve with very low resistance so as to eliminate shocks and
noises to reduce the load of motor and extend the operation
life of pump.
• Proper film temperature
The thin layer,
which is formed in internal wall of pipe by the fluid of light
oil or thermal medium at low speed and high temperature, is
called the film temperature layer. If the temperature of this
layer exceeds the permissible temperature, it will accelerate
the deterioration of thermal oil and therefore produce the
high boiling point material that will damage the inner surface
of tube. By our R&D, we have measured the precise value of
film temperature. Therefore the user will be able to operate
it safely.
