Regarding the torch testing issue at the LNG receiving station, I would like to ask the teacher for an explanation.
Thread Content
I am now preparing a plan for the torch test during the commissioning of an LNG receiving station, that is, the plan for the initial ignition. I have several questions now: 1. During the torch testing, is only the pilot light tested, or is the burner tested as well? 2. If only a pilot flame is used, how can we ensure that the burner will function properly when it is needed? If it is necessary to test the burner, then how is it tested? Buy an LNG vehicle to vaporize gas and supply it for igniting the burner? 3. If we want to exclude the use of an LNG vaporization test burner for vehicle testing, this can seemingly be accomplished through an instrument signal. Please ask the teacher to help clarify my doubts; I have no experience in the LNG industry before. (With a certain knowledge base): handshake
When lighting a torch for testing, it usually involves lighting a perpetual flame; as long as the perpetual flame can be ignited, there is generally no problem with the burner
If it’s a perpetual light, then there’s no need for testing, right? Once it’s lit, it should stay lit forever. I’m not quite sure what a burner is Is it a ignition device or a torch tip?
The burner should refer to the torch tip; when testing the torch, one should first light the pilot flame and then test the burner
The burner is the torch tip, used for burning and emitting gases. I’m talking about ground torches, teacher.
Yes, first light the permanent lamp and conduct a test run. I’m not sure right now whether to test the burner, and how to test it Should I light it? Or just give an instrument signal to see if the control system responds?
I’ve never worked with ground torches; only companies with low environmental impact are allowed to use them. The refinery where I work generates a high level of pollution, so high-altitude torches must be used. Is the burner you’re referring to one that introduces steam to lift the flame or reduce smoke? If so, then they are quite similar.
LNG is a clean energy source; it does not require steam to ensure safe combustion of the exhaust gases, and is used only to handle excess superpressured BOG (natural gas).
:Q: Are there any experts on Q:Q:Q?
There’s no need to test the torch tip, right? What’s the point of checking that? Just see if it’s blocked or not However, the ignition system needs to be tested, and it can be done at the same time. Whether it is automatic ignition or manual ignition, it needs to be tested. Well, if there’s no gas available in the initial stage, it’s better to buy some externally and give it a try, to see if it can be ignited successfully and if it can burn continuously
The last edit to this post was made by hnan on 2016-3-2 at 17:12. For LNG, surface flares are generally used. The commissioning of such flares involves more than just lighting the ignition tube and the permanent light; it is necessary to determine the critical values for opening and closing each pneumatic valve based on the combustion conditions at various stages.
