Jan 08, 2016· It is present throughout the conveyor belt area and it sucks the coal dust and separates the clean air from the coal dust. The DE System sucks the coal dust from the conveyor belt, wherever there is coal dust. Generally it is located at the tail end of each conveyor belt as at the tail end, the coal falls from a higher point and creates coal dust.

Spark Detection and Extinguishment System Design - Hansentek
If your dust collector has a single main duct, then only one zone is required. The air in the ducts is travelling at a very great rate of speed and therefore carries a spark or ember very rapidly. Air transport speeds of 6000 ft/min. are not uncommon which means a spark can be carried 100 feet in one second.

Control and Mitigate Dust - martin-eng
A coal mining facility in China was experiencing dust and spillage from one of its conveyors. Fugitive dust lowered the air quality, clogged equipment and had the potential to affect workers' health. Misalignment of the belt caused piles of lost product that had to be cleaned up, reducing system efficiency and wasting labor hours.

Coal Dust: How to Prevent a Power Plant Explosion — F.E. Moran
Jul 27, 2018· What causes a heat source in coal-fired power plants? The main cause of heat is friction. When a conveyor belt collects coal dust, it becomes a fire hazard. Coal dust only needs to accumulate to a footprint size and already it is a fire hazard. As the conveyor moves, any friction that occurs can be enough of a heat source to cause an explosion.

Duct Tape Is Amazing... - Martin Eng
Duct tape is a fantastic tool. Duct tape can do many different things. Duct tape IS NOT a good dust seal. I was on the west coast investigating a dust issue where the plant had dust coming out of the bottom of the transfer point. For a solution, they kind of wanted to use foam so I knew it had to be applied when the material started to fall.

Is Water the Best Coal Dust Suppressant? – MinTech Enterprises
Water-only coal dust suppression systems use high volumes of water to wet coal fines and temporarily adhere them to larger coal pieces in order to prevent the fines from becoming airborne. This massive addition of water robs coal of its BTUs (heating value), causes plugging in chutes and hoppers, and creates a slippery environment.
