Though it goes without saying, no smoking around the dust collector should be strictly enforced. All dust collection systems build up static electricity. If these systems are not grounded, electricity becomes a hazard that could start a fire. Ensure a proper grounding kit is in place while keeping in mind a large system may need more than one kit.

Pulse Jet Baghouses. Baghouse are the most versatile dust collector style and can be used in all applications. Baghouse collectors with traditional bag filters are preferred for applications with larger or mixed range of dust particle sizes, heavier dust loading, fibrous/sticky dusts or higher temperatures (normally up to 550F, in some cases up to 750F with specialty fabrics).

energy cost. Normally coke and coal contain sulfur and moisture in varying quantities. These fuels usually to go through a mill to obtain the right particle size and then need to get dried, usually with the hot gases from the kiln. Finally end the gases are filtered in a baghouse before discharging to the atmosphere.

a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the air. Even when a mill is shut down routinely, there is a danger that any residual coal left within the mill will oxidise, which can explode as the mill is restarted. To prevent a coal fire, the mills can ...

Smoldering coal inside an idle mill can evolve into a big problem when the mill is started, agitating these accumulation combined with a high air to fuel ratio environment; PRB is one of the most difficult coals with respect to mill fires and explosions. Mill internal temperatures are generally high enough somewhere to ignite any type ofcoal.

The filter is usually in the form of cylindrical fabric bags, hence the names "fabric filter" or "bag house", but it may be in the form of cartridges that are constructed of fabric, sintered metal or porous ceramic. In general, fabric filters are capable of collection efficiencies greater than 99 percent. There are three types of fabric filters.

Fires or explosions most likely occur during startup and shutdown of a coal mill system. If a small amount of coal remains in the mill after it is shut down, it slowly increases in temperature. If the pulverized coal undergoes spontaneous heating and the coal mill is restarted with hot embers present, an explosion or fire is possible.

Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs.". A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.

from the furnace fire. The coal/ air mixture enters the furnace through a burner nozzle at velocities in excess of the flame speed. Thus, the flame front is held stable at a distance away from the end of the nozzle where the coal/ air mixture velocity has slowed and is equal to the flame speed. From this we see the importance of
