What are the most common LNG air heated gasifiers?
According to different pyrogens, LNG gasifiers can be classified into three types: heating gasifier, environmental gasifier and process gasifier. According to the economic development of the operation of the environmental gasifier, the environmental gasifier is adopted at most. However, Doer to the cold winter in the northern region, the heating gasifier needs to be used for heating and gasification in order to consider the provisions of the process. Next, the most common air temperature gasifiers and water bath heaters in LNG stations are introduced in detail.
（1） Water bath heater
The water bath heater is used to heat the gasified natural gas in winter when the outlet temperature of the gasifier cannot meet the process regulations. Shell and tube heat exchanger structure is often adopted,
The water bath heater is composed of shell, heat transfer tube bundle (snake tube), tube sheet and other components. The tank shell of water bath heater, hot water boiler and other pipe fittings form a closed water circulation system. Hot water flows in from the lower part of the heater and out from the upper part, and the hot water fills the whole tank shell. Low temperature natural gas gets heat through a serpentine tube immersed in hot water to increase the temperature of natural gas.
（2） Air heated gasifier
Air temperature gasifier is also called air bath gasifier. The utility model is specifically composed of a star fin heat conducting fin, a liquid gas guide pipe, a support, a base, an inlet and outlet connector and other components. The star fin heat conduction pipe has eight corresponding fins, and the material is LF21 antirust aluminum alloy.
When the air temperature gasifier works, it makes full use of the surrounding atmosphere as the heat source, absorbs the heat of the air through the LF21 star tube with excellent thermal conductivity, and carries out heat exchange, so as to gasify the low-temperature liquid into a gas at a certain temperature. However, since the air contains water vapor and the working time is too long, the gasifier will frost, resulting in the reduction of gasification efficiency. Therefore, two groups of air heated gasifiers are set during operation, one for use and one for standby.
The above basis is often seen by LNG vaporizers. For more information, please contact vaporizer equipment, service hotline: 0512-81666096. Doer equipment specializes in the production of air temperature vaporizers, water bath vaporizers, vacuum storage tanks, etc. welcome to inquire.
