Cold torch Hot torch Temperature
Thread Content
How is it determined whether a flame is considered cold or hot? Is it based on the inlet temperature? So, at what temperature in degrees Celsius should it be classified as a cold flame? By the way, I saw some information stating that heat is supplied to the torch when the temperature is above 4e; I’m not sure what exactly 4e corresponds to in degrees Celsius
The following content is from the Internet: The so-called cold torch generally refers to the safe venting of a synthetic refrigeration system. For example, ammonia is at -33°C at standard pressure. There is also the venting from low-temperature methanol washing processes, where the temperature is very low as well. In some cases, direct venting is used, but such flares are prone to crystallization and blockage. To prevent crystallization, steam can be used for heating; in other cases, the gas from these vent points is sent to flares for combustion, although the temperature of the gas is very low. A thermal torch, on the other hand, refers to a torch gas that consists of other media other than those at low temperatures.
The gases emitted from the cold flare should be those that cause no pollution to the atmosphere; other gases go into the hot flare
Do the terms \"cold torch\" and \"hot torch\" mentioned by the poster refer to dry torches and wet torches? Discharge media that contain liquids should be discharged separately from pure gases; therefore, those with a dew point temperature below room temperature are sent to dry torches, while those with a dew point temperature above room temperature are sent to wet torches
A cold flare refers to a flare for cold emissions, that is, one in which the medium is discharged without combustion and is non-toxic and harmless. A hot flare, on the other hand, requires ignition. I hadn’t really thought about this distinction before, haha
A cold flare refers to a cold emission flare, right? It’s a system that discharges substances without burning them, and those substances are non-toxic and harmless. But is such a system still called a flare? Isn’t it just simply releasing the substances?
I just asked a friend who works for torch manufacturers; the difference between cold torches and hot torches lies in temperature. Another view is that cold torches do not burn, and there is no detailed standardized definition for this
By cold exhaust on our end, we mean exhaust at low temperature, which may be in liquid form; hot exhaust, on the other hand, is at normal temperature and consists of gases. But I’m just not sure about the temperature difference between the two.
