The molecular structure of nitrogen is so stable that it is usually very difficult to react chemically with other substances and shows great inertness, so it is often used as a protective gas in industry.
Nitrogen-filled storage of fruits and vegetables is an advanced method of storage and preservation, which allows fruits and vegetables to slow down their metabolism in an environment of high nitrogen and low oxygen, and to e...
The arrangement and distribution of multi-stream heat exchanger channel directly affect the heat transfer effect, and also the key to the design and manufacture of multi-stream heat exchanger and difficult point. All designs should follow certain principles and should not be designed at random. The general principles are: the same wall of the heat exchanger on both sides of the temperature as close as possible; the same flu...
