Is the explosion limit a fixed value? Why? Answer: The explosion limit is not a fixed value. Because it is influenced by factors such as initial temperature, initial pressure, inert gas content, container size, as well as the energy and properties of the fire source, among other things. http://bbs.hcbbs.com/static/image/hrline/4.gif Petrochemical Zone—New Ideas for Energy Saving: The “Creative Thinking” Campaign (The second phase of this campaign is in full swing) http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Industry Forum)
The explosion limit is a range between a lower limit and an upper limit.
Combustible gases do not explode only at a specific value; they can explode within a certain range. Therefore, the explosion limit is a range rather than a fixed value
No, because there are many factors that influence the explosion limit, and this limit varies in different environments! For example: pressure, temperature, oxygen content, etc
It is not a fixed value; it is affected by factors such as temperature, pressure, the container, inert gases, and ignition sources

No. For the same mixture system, the explosion limit can change due to factors such as initial temperature, system pressure, the amount of inert material present, the volume in which the mixture is contained, the material of the container walls, and the magnitude of the ignition energy. The general rule is that as the initial temperature of the mixture increases, the explosion limit range widens, that is, the lower limit decreases while the upper limit increases. As the system temperature rises, the internal energy of the molecules increases, turning what was originally an non-flammable mixture into a flammable and explosive one. As system pressure increases, the explosion range also expands. This is because higher pressure brings the molecules closer together, increasing the likelihood of collisions and thus facilitating combustion reactions. As pressure decreases, the explosion limit range narrows ； When the pressure drops to a certain value, its upper and lower limits coincide; the pressure corresponding to this point is known as the critical pressure of the mixture.
It’s not a fixed value; it’s a range.
