As the world continues to move away from fossil fuels, pyrolysis is becoming an increasingly important tool, helping to create a more circular economy by opening up opportunities in the production of alternative fuels from a variety of wastes. The rotary pyrolysis kiln is chosen …
Rotary drum tires, or riding rings, are one of the primary support components of a rotary drum, resting on trunnion wheels and allowing rotation of the unit on its base. As technology has advanced, the approach to mounting drum tires has evolved, with each change …
Activated carbon continues to attract interest as a way to produce a premium, marketable product from biomass waste. As a powerful adsorbent, the carbon-based material has been applied in everything from water treatment to gold recovery. The nascent nature of this industry, however, is leaving …
Rotary kilns are used across a number of industries to cause a chemical reaction or phase change in a material. This high temperature thermal treatment can be used to carry out a variety of different objectives, from catalyst activation to aluminum decoating. The number of …
Reduction roasting is the removal of oxygen from a component of an ore, usually through the use of Carbon Monoxide (CO). The CO is typically supplied by mixing a carbonaceous material such as coke or coal with the ore, or by feeding it separately. An …
Incineration has become an essential tool in managing industrial and municipal wastes more sustainably, as long-landfilled materials such as hazardous medical wastes, petrochemicals, ammunitions, and more, have proven detrimental to the environment. While many types of incineration equipment exist, the rotary kiln, a diverse and …
This week’s photo shows a rotary kiln’s leaf seals. The set-up consists of a series of overlapping spring steel plates that are attached to the housing, and ride on the rotating shell. Rotary kilns run at a higher temperature than the ambient air, thus any …
Variable Frequency Drives, or VFDs, are not a new technology, but only in recent decades have advancements in the field lowered many of the barriers associated with widespread VFD use, allowing their application in a range of settings. A recent market study anticipates that the …
Incinerators across the United States and abroad are preparing for a tidal wave of medical waste from the COVID-19 pandemic, with some countries already in the thick of it. As waste management companies prepare for the increased demand, we’ve put together the list below on …
Thermal desorption is the process of using heat to drive off an organic chemical from an inorganic mineral. Unlike incineration, it is a separation process that relies on different reaction temperatures of absorbent minerals and chemicals. The organic chemical is vaporized at high temperatures, resulting …
