flame safety lamp  types relighting procedure limitation test to be done specification for use components Open sidebar Flame Safety Lamp Types A flame safety lamp is a portable lighting device that is designed to be used in potentially explosive atmospheres. There are several types of flame safety lamps, including: Davy lamps, which are the oldest type of flame safety lamp and use a mesh screen to protect the flame Carbide lamps, which use a chemical reaction between water and calcium carbide to generate a flame Electric lamps, which are powered by batteries or other electrical sources and use a small flame to ignite a gas or other fuel The relighting procedure for a flame safety lamp will depend on the specific type of lamp. For example, a Davy lamp may need to be re-lit using a match or lighter, while a carbide lamp may need to be refilled with water and calcium carbide. The limitations of flame safety lamps include the need for frequent maintenance and refilling, as well...

 Coal Dust Explosion  Definition  An explosion is the Sudden combustion process of great intensity characterised by mechanical destructive effects through pressure and heat. For coal dust to ignite, combustible dust may be present in form of thick clouds.  Thick cloud of coal dust + O2 + ignition source (flame) ==> initiates combustion of coal Stages of Coal dust combustion stage 1  Ignition often starts as a puff, i.e. sudden combustion of part or whole of the air-borne dust with high temperature, but no marked effects. stage 2 The transition from Puff to Explosion; during this stage Pressure in burning layers increases as the heat of combustion, is transferred to surrounding unburnt layers due to radiation. stage 3 full fledge explosion; when the pressure value exceeds a certain value, a full-fledged explosion in which combustion occurs at a very rapid rate as a result heat is transferred totally rather than lost to its surrounding.  once the pressure ...
