Dust Collectors For Material Conveying
By: oleg tchetchel
Dust collection, fume removal, and material conveying systems each have unique characteristics, but all three are similar in their dependence upon proper air velocities. Dust collection and fume removal are generally thought of as “housekeeping” systems that usually incorporate a hood at the system entry point. There are many types and styles of hoods in common use, and hood design is a subject in itself. Some state and local codes offer hood design criteria, and there are several reference texts, such as Industrial Ventilation - A Manual Of Recommended Practices, that can assist in the selection and design of hoods. In all cases the hood design should minimize turbulence and offer the lowest possible entrance losses.(read

Industrial Pneumatic Conveying
By: oleg tchetchel
Pneumatic conveying is the transport of material from one location to another using air as the conveying medium with which the material is moved. Energy is needed to transport the material from one place to another. This energy can be supplied by a mechanical method (such as conveyor belts, buckets, etc), fan, blower, or a compressor. This newsletter will focus on the use of a fan to convey material.(read

Pneumatic Conveying Blower Systems
By: oleg tchetchel
A well designed pneumatic conveying system is often a more practical and economical method of transporting materials from one point to another than alternative manual or mechanical systems. This article outlines some of the fundamental principals of pneumatic conveying systems and explains various special considerations for fan selection.(read

How To Increase Fan Performance
By: oleg tchetchel
Industrial processes and plant ventilation systems often need more air than originally designed. Increased production requirements, process changes, and facility renovations are a few of the major reasons. Additionally, the lack of adequate maintenance over time can negatively impact system airflows. This article discusses several procedures that can increase airflow. Often airflow can be increased by adhering to proper fan maintenance procedures as outlined in fan installation and maintenance literature.(read

The Effect Of System On Fan Performance
By: oleg tchetchel
Fans are typically tested and rated in prescribed test configurations defined by the Air Movement and Control Association. This is done to ensure standardized procedures and ratings so that system designers can make realistic choices among various manufacturers. Beyond the routine system resistance calculations, the location of some common components and their proximity to he fan inlet or outlet can create additional immeasurable losses commonly called System Efect. These losses, if not eliminated or minimized, will necessitate fan speed and horsepower increases to compensate for the performance deficiencies.(read

Combustion Fans
By: oleg tchetchel
The combustion of coal and most fuel oils will release sulfur fumes into the flue gas. If a wet scrubbing or cleaning apparatus is used, water vapor will combine with the sulfur to form sulfuric acid. This can place severe constraints on the fan types available to handle this highly corrosive gas stream. For this very reason, flue-gas-desulfurization equipment is designed into the pollution control systems of many combustion processes. Another alternative to reduce the potential for sulfuric acid in the exhaust system is to mix lime or crushed limestone in a fluidized bed combustion process so the lime will neutralize the sulfur and stabilize the pH of the exhaust gases.(read

Mechanical Draft Fans
By: oleg tchetchel
The burning of gas, oil, coal, or other combustible material requires air. When the end result of the burning is to be an efficient combustion process, in compliance with Federal and State Clean Air Act requirements, the volume of supply air must be reliably controlled. Insufficient air volume will result in wasted fuel and excessive particulate along with potentially explosive gases in the exhaust system. Too much air increases the amount of heat carried up the stack by the excess draft. Either extreme increases the cost and difficulty of controlling exhaust emissions.(read

Spark Resistant Fas And Blowers
By: oleg tchetchel
Fan applications with airstreams of explosive or flammable particles or gases require spark-resistant system components for the safe handling of such airstreams. This includes components such as ductwork, dampers, filter devices, heating or cooling coils, and fans. This article presents practical considerations and methods of providing fans with varying types of Spark-Resistant Construction (SRC). The Air Movement and Control Association (AMCA) established a standard set of Classifications for Spark-Resistant Construction.(read

In-line Fan Vs Centrifugal Blower
By: oleg tchetchel
Fans have blades that force air to move along the shaft about which the blades rotate. Axial fans blow air across the axis of the fan, linearly, hence their name. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in wind tunnels.(read
