Methods to Eliminate the Ignition Sources from the Risky Location
There is always an explosive “fire triangle”: the Fuel, the Oxygen and the Ignition Source (the so called spark). The three elements enclosed in the “fire triangle” are always required, so as to support the fire.
The quantity of the fuel to the oxygen could be limited something between the fuel’s normal explosive limits and the ignition source which may further discharge the necessary energy with a view to ignite the explosive mixture. In order to eliminate of the risk for the possible danger, you need to take out all these three elements.
What’s the method to eliminate all the ignition sources from the possible risky location? Nothing good like an explosion proof enclosure. Internationally accredited explosion proof which is needed for a possible risk, has to be quite strong, for resisting all the inner pressure that might build up and could bring an explosion.
Design an explosion proof enclosure in such a way that it becomes easy for you to emit all the hot gases resulting after the process in a way that, the agreement will be cooled under the risky ignition temperature, in case there is a hazardous gas in the system.
These explosive proof enclosures are made either from some cast aluminum or some heavy cast steel and, so as to cool all the resulting gases the projected enclosures will require some wide flanges that will need to be grounded to an end and a very good tolerance.
Along with the threaded covers, the explosive proof enclosures would produce similar effect using the long and narrow path that is through the threads. While the hot gases from the potential internal explosion will go through all these long and narrow tubes, these things will free all the heat to the actual metal and the pressure is much reduced.
As it is convenient, torque all the cover bolts. Also, see that the flange surfaces need to be protected from the scratches, every time. The improper damaged surfaces will make it easy for all the hot resulting gases to ignite or get them away, suppose you’re managing an explosive situation outside the explosive proof enclosure.
These electrical products are usually present in each industry sub-domain, and the electrical materials will be labeled for the normal usage in a particular environment as it is specified in the National Electrical Code or in the IEC Standards.
