Low-temperature liquid gasification devices: advantages and disadvantages of water bath and steam types?
Thread Content
The liquid oxygen vaporization unit here is of the water-bath type, and its advantage is stable pressure and flow rate after vaporization； I wonder what the advantages and disadvantages of the steam version are? Dear experts
What is used to heat the water in your water-bath type carburetor?
I’ve never seen steam used directly for rewarming; usually, it’s a steam-heated water bath vaporizer.
Steam heating or electric heating can be chosen.
I guess the original poster wants to know the advantages and disadvantages of water bath therapy versus air bath therapy! Stable in a water bath, as the temperature on the water side remains stable and it is less affected by external environmental temperatures, making it suitable for high-flow applications ； Air bath cooling is energy-efficient, but it is highly affected by air temperature; it is not suitable for long-term operation in cold regions in the north. It is generally used as a backup pump in case of emergencies (when there is no steam available during an emergency shutdown), and it is appropriate for low-flow applications, as the investment required for high-flow use is too high ； For reference!
The original poster seems to be asking about the differences, advantages, and disadvantages between dry bathing and wet bathing. 1. In terms of energy consumption, wet bathing requires steam and water resources, whereas dry bathing involves no energy consumption at all. 2. The air-bath type carburetor, as mentioned above, is suitable for low flow rates and is highly affected by environmental conditions such as rain and snow. Additionally, it occupies more space, and in special cases two units (one in use and one as a backup) are required, which increases the cost.
I guess the poster is asking whether there are models that use direct steam heating, rather than heating a water bath to then reheat the low-temperature liquid.
You also mentioned the advantages of a water bath: stability and ease of control. Direct heating with steam is fast, but difficult to control; for vaporization, a high temperature isn’t necessary, and if steam is used directly, the efficiency of heat utilization is very low.
Can steam directly heat liquid oxygen? It is recommended to ask other colleagues; the temperature difference between hot and cold is too large, and the heating is uneven. . It should be a water bath type; everyone upstairs has made that clear
Are there any examples of electric heating?
