How to distinguish between liquid heating element and dry-burning heating element?
The shapes of liquid electric heating elements and dry-burning electric heating elements are similar, how do we distinguish between liquid electric heating elements and dry heating electric heating elements?
1. The difference in appearance:
Most of the liquid electric heating elements are threaded single-end tubular heaters, U-shaped or special-shaped tubular heaters with fasteners, and flanged tubular heaters.
Dry-fired electric heating elements are more common in single-ended straight rod electric tubular heaters, U-shaped or special-shaped electric tubular heaters without fasteners, finned tubular heaters, and very few flanged tubular heaters.
2. The difference in wattage design:
① The design of the electric liquid heating elements to determine the power according to the heating medium.
Heating water per meter of electric heating tube heating zone length do 3KW power
For heating corrosive liquids and water that is harder and easier to scale, the power per meter is about 2KW.
The maximum power per meter of heating oil is 2KW, and the power per meter of poorer and thicker oil is about 1KW.
② The dry-burning electric heating elements is designed to determine the power according to the fluidity of the heated air.
The power of the dry-burning electric heating element heated in a confined space is designed to be 1KW per meter.
The electric heating element with fan circulation in the flowing space is designed to have a power of about 1.5KW per meter.
3. Different material choices:
① Liquid electric heating element
For oil
Oil heating is normally made of stainless steel 304, but for customers who are used for experiments and pursuing low cost can also use carbon steel.
For water
Stainless steel 304 is used for heating tap water, and stainless steel 316 is used for drinking water. For turbid river water or water with more impurities, you can use scale-resistant coating electric heating elements.
For corrosive liquid
Stainless steel 316 can be used for liquids with low alkaline acidity and weak corrosiveness.
For strong acid and alkali, you can contact us to chose the material.
② Dry heating electric heating element
If it is not used for a long time, you can use carbon steel material for testing.
The working temperature is 100-300 degrees, and stainless steel 304 is recommended.
The working temperature is 400-500 degrees, and stainless steel 321 is recommended.
The working temperature is 600-700 degrees, and stainless steel 310S is recommended.
If the working temperature is around 700 degrees -800 degrees, it is recommended to use imported materials from Ingle.
From the above introduction, we can know that the shape design, power design and material selection of the dry-heating tubular element and the liquid tubular heater are all very different. I hope this will be helpful, you can distinguish between them to choose the right components according to your needs quickly.
