LNG ambient air temperature vaporizer is a new type of energy-saving gasification device that utilizes the characteristics of gas decompression gasification such as liquefied petroleum gas (LPG) and liquefied natural gas (LNG) to realize gas gasification. Its main part is the heat exchange device, which can obtain greater heat from the air control in the smallest possible space. In other words, it is to let liquid petroleum gas and liquid natural gas "flow through" the air-heated vaporizer, and let the air heat the cold petroleum gas and natural gas to turn them into gaseous petroleum gas and natural gas.
Nowadays, there are generally air-temperature supercharging and water temperature supercharging. I personally think that water temperature supercharging is better, and air supercharging will not cause slow supercharging in winter.
When the temperature of LNG gas in the air-heated vaporizer is lower than how much should it be heated? The secondary heating should be 5 degrees Celsius; because the temperature is lower than -10 degrees Celsius, it may damage the film of the pressure regulator, the flow meter and the buried PE pipe;
You have to distinguish whether the gasification capacity is insufficient or the ambient temperature is low. The outlet temperature of a normal air-temperature vaporizer is 3-8 degrees Celsius lower than the ambient temperature. If the temperature in the north is already lower than 0 degrees Celsius, the outlet temperature should be lower than 0 degrees Celsius. Then turn on the second heating.
If the temperature is more than 10 degrees, but the exit temperature is low, it means that the gasification capacity is insufficient, and the number or specification of the vaporizer should be increased instead of secondary heating.
