explosion limits are not limited just to a certain particle size of combustible dusts. Explosion limits (LEL, lower explosion limit) can only be detected by performing . specific tests. Extracted dust may create dust explosions. A precondition for a dust explosion is an . explosive environment. Dust explosions only occur under certain . conditions.

Coal, Cement & Steel: Dust Explosion Venting The Very Best in Explosion Venting for the Coal, Cement and Steel Industry The cement and steel industries have a long association with coal as a source of heat in their kiln plant but now they experience the changing times of more sustainable fuels sources from tyres to sludge pellets.

The ATEX Equipment Directive is primarily concerned with the manufacture and sale of products for use in hazardous locations (i.e., explosive atmospheres), including mines, oil rigs, petrochemical plants, fuel storage facilities, grain processing, flour mills and paint finishing areas.

Having left the mill at the top, the final product continues with the gas to the filter or cyclone, where it is collected. Tailor-made layout The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding

Explosion-Proof Cameras---- 3 1. BACKGROUND In some industries such as coal mining, oil exploitations, chemical plants, textile mills, etc., there will be explosive gas, steam, or dust during the production process.

ATEX Category Equipment Protection Levels Typical Zone Suitability 0 A place in which an explosive atmosphere is continually present 1 G Ga Equip. suitable for Zones 0,1,2 20 1 D Da Equip. suitable for Zones 20,21,22 1 A place in which an explosive atmosphere is likely to occur in normal operation occasionally 2 G Gb Equip. suitable for Zones 1,2

connected to places where an explosive atmosphere may occur. This will provide information on any areas away from the source of the hazard to which an explosive atmosphere may spread, for example through ducts. Such areas should be included in the classification system for places where explosive atmospheres may occur.

dusts are capable of forming a potentially explosive atmosphere when dispersed in air or alternative oxidant. EU Directive 1999/92/EC, the ATEX 137 Directive and the transposed legislation in EU Member States requires that a Hazards Area Classification be carried out.

ATEX is the name commonly given to the two European directives for controlling explosive atmospheres. ATEX lifting equipment can mean electric chain hoists, wire rope hoists and belt hoists, winches, trolleys and pneumatic lifting equipment, and can be …

Explosive dust atmosphere not likely to occur in normal operation but may be present for short periods Bespoke Control Stations For Hazardous Areas T&D's in-house CAD drawing facilities produce hazardous area certified control stations for international oil, gas and petrochemical projects – ATEX certified for Zone 1, 2, 21 & 22 gas and dust ...

(coal dust and methane containing atmospheres). Explosion group II is for all remaining potentially explosive atmospheres. This group is divided into IIA, IIB, and IIC. These subdivisions are based on the different non-transmission of an internal ignition and the ignitability of the gases and vapours. A IIC-classified equipment covers any

connected to places where an explosive atmosphere may occur. This will provide information on any areas away from the source of the hazard to which an explosive atmosphere may spread, for example through ducts. Such areas should be included in the classification system for places where explosive atmospheres may occur.

ATEX and IECEx Approved Explosion Proof Vertical Float Switch – This is a vertical magnetic float switch for control and indication of a liquid level while in a potentially explosive atmosphere. ATEX and IECEx Approved Explosion Proof Continuous Vertical Liquid Level Sensor – This is a magnetic float on a reed switch or Hall Effect sensor ...

The traditional ignition triangle shows the 3 parts which are required to be present 1 for an explosion to occur. The protection methods detailed in the EN 60079 standards are designed to remove at least one of those parts, the exception being Ex d flameproof 2.. Fuel can be Dust or Gas/vapour, Although the purists would argue Gas and vapour are different, within the context …

ATEX/IECEx Markings Explained Area Classification Equipment Category Definition Zone An area where an explosive atmosphere is present continuously or for long periods (over 1000 hours per year or >10% of the time) An area where an explosive atmosphere is likely to occur in normal operation (10 - 1000 hours per year or 0.1 to 10% of the time)

Every company must classify in ATEX zones the areas where explosive atmospheres may form and where special precautions need to be taken to protect the safety and health of workers. Aspects to be considered: the type of substance causing the explosive atmosphere, the frequency with which it occurs and its duration.
