Multi-cyclone dust collectors (MDCs) have been used in conjunction with air preheaters and boilers in energy production and other industries since the 1950s. Over time, they have evolved in design and purpose, yet their function remains important in many process heating applications.
Continuous drying systems can effectively dry or dehydrate many products in the process markets. When considering continuous-conveyor vs. fluid-bed or rotary industrial dryers, keep these points in mind.
Many industries utilize heat for manufacturing processes. Whether the application involves removing residual moisture on the surface of a part, drying a coating on cable assemblies or the preheating of metals during a forming process, heating is one of the driving components.
When it comes to lining fired heaters in the petrochemical industry, refractory ceramic fiber has been the go-to material, but it has its drawbacks. Consider an alternative material and learn how it can mitigate refractory ceramic fiber’s limitations.
In the petrochemical world, refractory ceramic fiber (RCF) — also known as aluminosilicate wool (ASW) — has long ruled as the material for lining fired heaters. It is not hard to understand why: The material possesses several attributes that ensure it performs well in the harsh environment.
Imagine a machinist running a screw machine, turning out hundreds of parts with a male thread. To verify the thread size is in tolerance, he or she checks samples using two gauges with corresponding female threads.
ANSI/AMCA Standard 208, Calculation of the Fan Energy Index, can be downloaded at no cost from the online store of Air Movement and Control Association (AMCA) International Inc. through the end of 2019. AMCA opted to release it for free to help disseminate the information to fan builders and buyers.
A welding parameter web application is available for Asahi/America’s line of piping systems and welding equipment. The web-based tool contains specified welding information for 14 of Asahi/America’s butt and socket welding tools.
An aerospace company will use an electrically heated batch oven to cure epoxy resins and varnishes on assorted parts. Manufactured and shipped by Wisconsin Oven Corp., the heavy-duty unit has a maximum operating temperature of 500°F (260°C).
A safety digest highlights the value of worker participation to prevent chemical incidents. Produced by the U.S. Chemical Safety Board (CSB), the digest notes that lack of worker participation was a factor in several major incidents investigated by the CSB. In each case, workers and their representatives were not engaged to help identify hazards and reduce risks.
Babcock & Wilcox formed a strategic collaboration with John Zink Hamworthy Combustion. The agreement pairs John Zink Hamworthy Combustion’s Coen burners with Babcock & Wilcox water-tube package boilers. The arrangement allows both companies to market the combined burner and boiler solution to their customers.
With more than 140,000 steam boilers in operation worldwide, Miura has never had a pressure vessel explosion resulting in casualty. The company’s focus on safety did not stop with product design performance, however. Shortly after opening its U.S. manufacturing facility in Rockmart, Ga., in 2009, Miura set out to achieve the distinction of becoming the safest workplace in the steam boiler industry.
Users can shield steel piping from corrosion with cathodic protection to prevent corrosion, says the manufacturer. The technique reduces the corrosion of the metal surface by making the surface of the cathode an electrochemical cell.
The D Series offers nominal throughputs from 600 to 5000 lb/hr (272 to 2268 kg/hr). All models in the company’s large-dryer line are built around desiccant-wheel drying technology, a common touchscreen control, and a set of standard features.
