Heat exchanger insulation layer
Thread Content
Dear experts, could you please advise me on how to choose the thickness and material for the insulation layer of a heat exchanger? Who knows; I hope you can offer your guidance!
It is necessary to know parameters such as the size of the heat exchanger and temperature
Looking at the parameters of your heat exchanger, there are specialized design documents for insulation and heat retention
Reply to 4# Fengwu Jiutian1022: I’ve already finished the design. How do I calculate the thickness of the insulation layer? Are there any relevant design software tools that can help with this? Thank you!
If the diameter of the heat exchanger is not large, such as less than 1000 MM, then select the insulation material and thickness based on those of pipes with an equivalent diameter and at the same temperature. For example, if your diameter is 600 and the temperature is 150 degrees, then you should look up the insulation methods for pipes with a diameter of 600 and a temperature of 150 degrees. No software is available.
The minimum insulation thickness can be determined based on the ambient temperature of the equipment installation site (whether it operates year-round or seasonally, and whether it is indoors or outdoors), the maximum heat loss, the temperature of the medium, etc； There is also the economic thickness (the thickness that minimizes the sum of the investment cost for the insulation material and the heat losses during operation); generally, empirical data can be found in thermal engineering handbooks.
