Jeffrey Rader - Pneumatic Boiler Feed Systems
High Pressure, Low Pressure and Vacuum Conveying Systems for Pulp & Paper Mills or Biomass Systems and for Boiler Direct Injection Systems. Efficiently move chips, bark, and RDF bulk material over a long distance, elevate it in a short distance, or inject woody material directly into a boiler. Pneumatic conveying rates of more than 1,000 tons per hour can be achieved with these systems. Jeffrey Rader designs ruggedly built rotary valves, cyclones, wear back elbows, ducting and blowers for tough, high-pressure, high-volume and abrasive pneumatic conveying applications. With more than 50 years of experience and 10,000 installations in pulp and paper mills around the world, Jeffrey Rader has the application knowledge to design and build your pneumatic conveying systems.
Boiler Fuel Feed Systems
Jeffrey Rader Boiler Fuel Feed Systems are typically made up of a combination of metering and conveying equipment such as underpile screw reclaimers, drag chain conveyors, screw conveyors, robbing screws, slide gate valves and rotary airlock/feeders.
Depending upon the desired flow rate to the boiler, this system of equipment can be speed controlled faster or slower to obtain that desired flow rate.
Because this type of boiler fuel feed system is made of a collection of conventional and standard pieces of conveying equipment, it has the benefit of many years of industry experience with reliability of those types of equipment.
Digester Charging System
The Jeffrey Rader digester charging system converts the classic batch cooking process into a Continuously Operated Digester. A digester installation eliminates disadvantages such as excessive labor costs. One operator can operate and control the various functions of the charging system from a control room.
Automation is another benefit since the system can easily be remote controlled or fully automated utilizing simple mechanical or electro/hydraulic components. This provides a controled and uniform management system.
The Jeffrey Rader Digester Charging System provides uniform pulp quality. Pre-heating, preimpregnation, liquor-impregnation and circulation are all elements that also add to the uniform pulp quality. The Digester Charging System is completely enclosed from the infeed to the point of discharge into the digester. Conveying air is separated in the cyclone and evacuated to atmosphere.
The air evacuation system operated during the chip filling prevents the air and incondensible gasses from disturbing the chip flow pattern.
As an additional benefit of this system, all the digester gasses containing mercaptans and other toxic components which otherwise escape to the atmosphere, are collected and can be blown to the recovery boiler or other air pollution control device.
