Petroleum Coke Baghouse by Jardar Systems, Inc. This Petroleum Coke Mill baghouse was specially designed and recently supplied to a cement company. This plant uses an indirect-fired milling system for firing the kiln. With an indirect fired system, all the coke is pulverized by the mill under a high negative static pressure. The milled particles are fluidized, ducted to an air classifier where those particles greater than the cut diameter are sent back to the milling machine, and the smaller particles are transported through the "Pressure Relief Hood" to the baghouse. The baghouse captures all the coke particles and transfers them by screw conveyor and rotary airlocks to the pulverized coke silos.

Explosion Vents on Baghouse This "Process Dust Collector" is a key component of the pulverized coke mill. The baghouse is designed to handle a very heavy inlet dust loading, produce a low differential pressure drop, and structurally withstand and vent an explosion. To protect the ductwork, baghouse, and other system components there are several proprietary design components for this system. The first is the Pressure Relief Hood located adjacent to the baghouse. This large resealable hood is designed to open when an explosion (deflagration) occurs in the system. This relieves the explosive pressure thereby assuring that the system components are not damaged. Also, the baghouse has specially engineered resealable explosion doors for releasing the explosive pressures inside the baghouse. Lastly, the proprietary grounding system and fabric filter removes the potential static charges that can build up in the system.

Primary Clarifier by Jardar Systems, Inc. This Primary Clarifier was supplied recently to a company with seven (7) wet scrubbers. Primary clarifiers are used to conserve water by allowing particulate to settle out from the scrubber recirculation water. This clarifier is a drag-bar type settling tank utilizing a low-profile design, which maximizes the settling area for the available floor space.

Weir Troughs The incoming scrubber recirculation water enters the clarifier through the baffled center trough. This trough distributes the liquid throughout the tank while minimizing surface turbulence. Note the two (2) V-notched weir sections that are designed to keep an accurate liquid level in the clarifier based on the incoming liquid flow rate. The weir sections are designed to permit clarified liquid to spill over into the respective flow channels. The clarified scrubber recirculation water then flows through these channels into the clearwell and is pumped back to the scrubbers.

Drag Chain Section Settled particulate is conveyed from the bottom of the tank by means of a heavy-duty drag chain/angle flight system. This drag-bar conveyor consists of several submerged idler shafts with guide sprockets that properly route the attached angle flights through the tank bottom and up the sloped plate to discharge the material at the head section. The heavy-duty drag chain is powered by means of a single drive shaft at the top of the sloped tank, which in turn is driven by a motor-operated gear reducer.
