Can the tubular heater of water tank heat oil?


The difference between water tank tubular heater and oil tubular heater is that one heats water and the other heats oil. The density of water is different from that of oil, and the speed of heat conduction is also different. So when designing the tubular heater, the power per meter of oil and water is different.

INDUSTRIAL HEATER

Let's take the flange electric tubular heater as an example.


1. Normally speaking, when heating ordinary tap water, we will design the flange tubular heater according to the power of 3KW per meter, while for heating ordinary heat transfer oil, we will generally design according to the power of 1.5KW per meter. So if the flange tubular heater of water tank (if the flange tubular heater is designed according to the relationship of 1:3kw) is put into the heat transfer oil for heating, what will happen? The answer is that the tubular heater of the water tank flange will burn out soon. Because the heat transfer oil is thicker than tap water and the heat conduction is relatively slow, heating the heat transfer oil by the tubular heater of the water tank with large surface load will cause the surface temperature of the heating pipe to be too high, at the same time, the rate of carbon deposition on the surface will be increased and the service life will be shortened.


2. When the heating water quality is poor: we will design according to the power of 1-1.5kw per meter to reduce the surface load of the tubular heater. At this time, if the water tank heating pipe is used to heat the ordinary heat transfer oil, the power is similar to that of the heat transfer oil flange heating pipe, so the water tank flange tubular heater can be used to heat the heat transfer oil.
