In the production of powdered food or pharmaceutical products, one process step involves drying the product. This is commonly done by a fluid bed or spray dryer
Code: EAP 1003
Supplier: Fike
Dust collection involves the removal, or collection, of solid particles from a flowing air stream, for the purpose of eliminating nuisance dust, the safety and health considerations of employees, product quality improvements, and the collection of powdered products.

The pulverization of coal to improve burning efficiency and maximize energy output is a method that has been used for more than 75 years. Pulverized coal processing and storage systems are typically found in power generation, steel and iron manufacturing, cogeneration, cement drying, and other industries that employ injection furnaces.
Code: EAP 1005
Supplier: Fike
The nature and operation of dust collection equipment present possible fire and explosion hazards, due to the greater concentration of small particle material. Dust collectors experience more explosions than any other process vessel types.
Code: EAP 1006
Supplier: Fike
The powders produced fromliquid feedstocks are suspended in the spray dryer at elevated temperatures presenting possible fire and explosion hazards. in the production of food or pharmaceutical products, there could also be residue solvents (hybrid mixtures), that increase explosion hazards.

Supplier: Fike
Bucket elevators are among the most common conveyors used for making vertical lifts of bulk materials. The materials being conveyed can vary over a wide range of sizes, from powders to pellets. Most of these bulk materials inherently produce dusty conditions within the bucket elevators, creating explosion hazards.

Supplier: Fike
Raw coal is fed into the coal inlet, dried and ground to a fine dust on the grinding table. Hot air (inert gas) is used to pneumatically carry the coal dust upward through the classifier and into the transport pipe.
Code: EAP 1010
Supplier: Fike
A dust collector (bag house) is typically a low strength enclosure that separates dust from a gas stream by passing the gas through a media filter. The dust is collected on either the inside or the outside of the filter. A pulse of air or mechanical vibration removes the layer of dust from the filter. This type of filter is typically efficient when particle sizes are in the 0.01 to 20 micron range.
Code: EAP 1011
Supplier: Fike
Dust laden gas enters the chamber from a tangential direction at the outer wall of the device, forming a vortex as it swirls within the chamber. The larger particulates, because of their greater inertial, move outward and are forced against the chamber wall. Slowed by friction with the wall surface, they then slide down the wall into a conical dust hopper at the bottom of the cyclone. The cleaned air swirls upward in a narrower spiral through an inner cylinder and emerges from an outlet at the top. Accumulated particulate dust is deposited into a hopper, dust bin or screw conveyor at the base of the collector.

In an electrostatic precipitator, particles suspended in the air stream are given an electric charge as they enter the unit and are then removed by the influence of an electric field. A high DC voltage (as much as 100,000 volts) is applied to the discharge electrodes to charge the particles, which then are attracted to oppositely charged collection electrodes, on which they become trapped.

A storage bin can contain either raw coal for feeding into the pulverizer, or pulverized coal for feeding into the burner. Typically coal is fed into the top of the storage bin. The heavy particles of coal settle in the hopper, while dust becomes suspended in the upper section. The dust can be the fines created during pulverizing, or the fines that are a by-product of abrasion as the coal being moved from one piece of equipment to another.
Code: EAP 1014
Supplier: Fike
Transport pipes and ducts are enclosures that move coal dust from one piece of equipment to another, or that brings heated gases into the equipment for process operation. These enclosures can range from lightweight sheet metal to heavy wall pipe. They can be round with diameters up to approximately 5 feet, or rectangular with cross sections up to approximately 2’x3’

• 1999, Coal Supplied 56% of the nations electricity.
• ~90% of coal mined in US goes to power plants.
• To meet forecasted electricity demand over the next 20 years, it is estimated that a staggering 2,000 MW of capacity, equivalent to two major power stations, will have to be built every week throughout the world - some 25% or more based on coal.
• Coal injection provides a unique opportunity to reduce coke usage and increase furnance productivity of blast furnaces. Additional, coal injection offsets or eliminates the costs associated with coke oven rebuiltds and repairs.
• The DOE estimates that the market for clean coal technologies will climb to $870 billion by the year 2010.

Cement manufacturing is one of the largest mineral commodity industries in the United States, with an estimated production capacity of greater than 73 million metric tons annually.

A cement kiln is the world’s largest moving manufacturing machine. Cement kilns are cylindrical ovens, some as long as 1000 feet and as much as 24 feet in diameter. They rotate one to three times every minute. The kilns are mounted at a slight incline. The inside is lined with fire resistant brick. Powdered coal, oil, gas, liquid waste-derived fuel, and solid waste fuel are used to fuel the kiln. Raw material enters the kiln and is heated to over 2700°F. The material leaving the kiln is called clinker.
Code: EAP 1018

Most manufacturing processes require the removal or collection of dust particles, whether that is eliminating nuisance dust or collecting powdered products. After removal or collection of dust particles, the solid particles typically must be separated from the flowing air stream.

This process includes a hopper for manually feeding product into a powder handling plant (see figure on page 2). Filling of product hoppers can cause dust particles to become agitated and suspended in air. This dust laden atmosphere can then support a deflagration if an ignition is introduced. A dust collector is installed onto the hopper to pull vacuum, which in effect limits the amount of dust that will become airborne both inside and outside the hopper when feeding the product.
Code: EAP 1020
Supplier: Fike
At an elevator facility, a truck unloading system is used to move grain from the truck into storage silos. While conveying grain throughout the system, fine dust will become airborne creating a risk for dust explosion in practically every process section (see Figure on page 3 from left to the right): truck unloading hopper, bucket elevator, silo and dust aspiration/filter system.
