The operating principle also works with other combustable fuels besides acetylene, but since most others have narrower explosive limits, the effect is not as reliable.
12.
An Explosimeter or combustible gas detector is a gadget which detects when any combustible gas has reached the lower explosive limit of admixture with air.
13.
Excessive constituent levels in soil could also potentially result in the generation of vapors in the desorber at concentrations exceeding the lower explosive limit ( LEL ).
14.
Many water cooled reactor containment buildings have catalyst-based recombinator units installed to rapidly convert hydrogen and oxygen into water at room temperature before the explosive limit is reached.
15.
:The lower explosive limit for hydrogen gas in air is about 4 %; that is, a mixture with air that contains at least 4 % hydrogen gas will burn.
16.
Ordinarily, vapor concentrations in the area of this filling operation are below the lower explosive limit ( LEL ) of the product being dispensed, so the static discharge causes no problem.
17.
At levels of 2000 ppm, 10 % of the lower explosive limit, LPG is considered immediately dangerous to life and health ( due solely to safety considerations pertaining to risk of explosion ).
18.
It can also occur during hot starting; high temperatures may cause fuel in the carburetor float chamber to evaporate into the inlet manifold, causing the air / fuel mixture to exceed the upper explosive limit.
19.
In this connection number of tsts are to be carried out for finding the parameters like Flash point, composition by using chromotography, auto ignition temperature, purity of sulphur, Lower and upper explosive limits of products etc.
20.
Acetylene in air has the widest range of explosive limit of any common chemical and also a very low ignition energy, a combination which very reliably produces a loud bang explosion compared to other vapor explosions.
