Activated Carbon Injection (ACI)

Storage and Handling Systems

Mercury Capture...

A Continuing Emphasis for U.S. Coal-Fired Power Plants

Stringent government mercury (Hg) emission regulations at the national and state levels require large mercury emission reductions at the nation's 1,100 plus coal-fired plants, which emit approximately 48 tons of mercury per year. Among the few proven mercury emission control technologies that exist, the predominant process is Activated Carbon Injection (ACI). Powdered Activated Carbon (PAC) injection is the only control technology proven to reduce mercury emissions in excess of 90%.

PAC Storage and Handling Systems

The cornerstone of Metalfab's PAC Storage and Handling System is the integration of the company's proven bin activators, activated Posibins™ and "Better-Weigh®" gravimetric feeders. These critical system components are integrated with process controls, instrumentation, knife gate valves, and interconnecting piping, all pre-installed within the skirt area beneath a fully engineered storage silo. This integrated system provides precise PAC metering to the final downstream injection system feeding the flue gas ductwork.

Metalfab successfully combines testing, equipment design, and system integration capabilities to offer fully integrated PAC handling systems directly to large environmental/boiler OEMs who supply complete ACI systems to power plants.

Standard Bin Activators

Overview

The tendency of dry solids to flow from bins in a sporadic or irregular fashion has perplexed the materials handling industry from its earliest days. Attempts to solve the problem have ranged widely - and wildly - from the use of a laborer with a sledge hammer, to rappers or vibrators and powerful blasts of air. Over the years no single method or combination of techniques ever provided a universally successful solution. Then in 1960, a revolutionary new concept was introduced which overcame the troublesome and costly problems of arching, bridging, and rat-holing. Called a "Bin Activator", the device consisted of a vibrated cone which was suspended beneath the bin, replacing a major portion of the standard fixed cone. Positive discharge was achieved through the successful application of the principles of vibration as well as by the design of the unit.

Today, the most effective bin activator designs incorporate the use of an internal cone-shaped baffle which is rigidly attached to the body of the bin activator by means of rugged structural tubular members. The entire bin activator unit moves horizontally in response to centrifugal forces generated by the unbalanced weights of an attached vibrator.

The cone baffle relieves the weight of the material from the lower section of the bin activator, and acts like a wedge as it moves beneath the material and pushes it in all areas adjacent to the cone's surfaces. This powerful force is also transmitted to the material in the upper portion of the bin as the motion is carried from particle to particle.

These moving particles cannot bridge or rat-hole, and flow freely around the periphery of the baffle toward the outlet of the bin activator. If the outlet is large enough and there is no downstream equipment to impede the flow, positive discharge is accomplished.

However, where flow is regulated by other devices, the material may become jammed or compacted at the outlet, causing a no-flow condition. The shape of the unit is irrelevant; it makes no difference whether it is dish-shaped, cone-shaped or multi-sloped. For as long as the material must travel from a larger dimension to a much smaller one at the discharge hole, convergence must take place. Vigorous vibration only serves to worsen the problem. To solve the problem, Metalfab introduced its secondary baffle design. The secondary baffle prevents jamming and compaction of the material at the outlet and allows for a constant flow upon demand.

PB: Posibin™

Overview

The Metalfab PB Posibin™ provides positive, problem-free discharge from storage of a wide range of difficult to handle materials - in a variety of densities and particle sizes. From micron-size powders to fibrous substances, materials flow freely, on demand, on a first-in, first-out basis.

The PB Posibin consists of a static cylindrical bin fitted with the unique Metalfab Bin Activator. This vibrating motorized unit, attached to the bottom of the static bin by vibration isolator-equipped solid steel suspension arms and flexible reinforced sleeve, provides continuous movement of the product in the bin. A conical primary baffle, mounted within the bin activator moves horizontally with the unit to keep the contents in continuous motion and eliminate potential flow-stoppages such as bridging, rat holing, etc.

An adjustable secondary conical baffle, located at the final outlet, moves at a slightly different amplitude to prevent jamming and compaction in that critical area.

Two PB Posibin models, with capacities from 3 to 750 cu. ft., handle materials with bulk densities to 200 lbs/cu. ft. The largest units are ruggedly mounted to the static bin by solid, carbon steel hangers capable of supporting more than 500,000 lbs. The Posibin may also be hung from overhead steel. Operation is almost completely noiseless.

"Better Weigh"^®
Continuous Weigh Feeders

For highly accurate, gravimetric feeding of dry bulk materials in batch or continuous operation

Overview

"Better-Weigh®" Batch/Continuous Weigh Feeders are designed to provide feeding in either batch or continuous mode depending upon the arrangement of the feeder's control electronics. In batch mode, the batch controller is used to control the fast (bulk) and slow (dribble) speeds of the feeder. Accuracies of ±0.5% can be easily achieved in 2 lb. or less batches, and ±0.25% with 3 lb. or greater batches with time spans of 30 to 90 seconds. In continuous mode, the feeder's electronic controller is used to constantly monitor loss-of-weight of material per time in order to maintain a continuous loss-of-weight with an accuracy of ±0.25% to ±0.5%.

Spin Loader

Overview

Metalfab's Spin-Loader lets you utilize bulk storage facilities to their fullest capacity. It eliminates the pyramiding which occurs when flakes and granular materials are loaded into bins, hopper cars and piles, and enables you to load up to 15% more product into virtually any storage facility without costly hand labor or interrupting flow. Spin-Loader distributes the product evenly in a 360° arc.

The compact, ruggedly-built Spin-Loader can handle up to 200,000 lbs. per hour of 90 lbs. per cubic foot material. It is simple to install and easy to operate, and may be mounted to the top of the bin or attached to a flexible loading spout and placed inside or over the bin itself. The entering material flows through the tube of the Spin-Loader to a motorized, spinning disc which directs it to the outer walls of the bin, permitting each bin or compartment to be filled to its maximum capacity.

This method of redirecting the particles greatly reduces the possibility of particle segregation, enabling the particles to intermix. And, since the entire loading system may be completely enclosed, product waste and contamination are eliminated.

Features/Benefits

Available Sizes: Two Models (SL100) 8 5/8" dia. inlet with a 2 HP motor and (SL200) 10 3/4 dia. inlet with a 5 HP motor.

Experience That Says We've Been There and Done That

Looking for a dedicated system to handle batching operations, or a complete system designed to regulate flow or meter discharge of product into a continuous process? Metalfab has the engineering experience and upstream/downstream equipment to meet most dry bulk solids material handling needs.

Should continuous feeding by volume be a requirement, a Metalfab Posibin™, Bin Activator, or Bulk Bag Unloader can be positioned upstream for trouble-free discharge of product into any Metalfab screw feeder. Hoppers on the feeders can be sized to handle product discharge without interruption of product feed.

Should feeding by weight be a requirement, a Metalfab "Better-Weigh®" Gain-in-Weight/Loss-in-Weight Feeder can be paired with a "Better-Weigh®" Controller to provide automatic feeding of product in batch or continuous mode. These sophisticated controls feature our easy-to-use touch screen with graphic display, automated feed rate optimization, discharge with batch histories, and multiple security levels with alarm/warning system.

A Metalfab Convey-All™ Flexible Screw Conveyor and CB1 Continuous Mixer can then be positioned downstream of the feeder's discharge outlet to move product into a process stream, storage container, bulk bag, drum, tote, multi-wall bulk box, or filling equipment.
