Temperature of liquefied gas

This question is really hard to address. Room temperature refers to the temperature in our daily lives, usually around 20°C. The operating temperature depends on the environment in which one is located, while the design temperature is generally higher than the operating temperature. I have no idea what you’re trying to do; the question is so strange.

Is LZ trying to ask what the typical design pressure for liquefied gas pipelines is?

Let’s start with the theoretical temperature: the theoretical temperature of an atmospheric stove can reach 1600°C, while that of an infrared stove is 2040°C, representing a difference of 440°C between the two. Based on the measured temperatures, the temperature of an atmospheric stove is around 680°C, while the core temperature of an infrared stove is around 1100°C; there is a difference of about 420°C between the two. Data on the combustion temperature for different gas sources is also hard to find, as the calorific value, Bunsen number, and outer flame temperature vary significantly depending on the classification of each gas source. For example, there is a significant difference between 3R artificial gas and 7R artificial gas. Infrared stoves have a significant advantage in terms of thermal efficiency, and they represent the future direction of development for the stove industry. I have done my best; if you think it’s off-topic, that’s evidence of how complex the issue is. On the other hand, the original poster asked a very naive question; natural gas, liquefied gas, and artificial gas are inherently complex, with unstable components, and their calorific value and outer flame temperature vary greatly. Take a look at the **standards – every grade for all gas types is covered by 3 test gases.

Thank you all. . . . . .

The design temperature for liquefied gas pipelines is generally set at -19 degrees; lowering this temperature requires the use of higher-grade materials, which increases the cost significantly. If it is confirmed that the operating temperature is at room temperature, the cost will be much lower
