In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing …
FEECO’s rotary dryers and kilns can accommodate numerous fuel sources. The chart below highlights the equipment and their available fuel source options: Natural Gas/Propane Fuel Oil Electricity Biomass Combustion Waste Heat Biogas Direct Rotary Dryer x x x x x Indirect Rotary Dryer x x …
Biochar has seen a surge in popularity as a soil amendment as of late, for the many benefits it can offer to soil and for its potential use in carbon sequestration. With a unique ability to capture and hold particles on its surface, biochar is …
The process of converting biomass to activated carbon can vary depending on the source and characteristics of the feedstock material, and the wanted end-product characteristics. This process is outlined in the stages below: Drying. Biomass must first be dried, most often via a rotary dryer, …
A recent white paper by William Strauss, PhD of FutureMetrics LLC, looked at a strategy that could breathe life back into the dying US coal industry, and the answer comes from an unlikely place: implementing policy to support the co-firing of wood biomass pellets (biocoal) …
Activated carbon is a diverse adsorbent, playing a key role in a number of applications, particularly in relation to environmental recovery and purification. Among a myriad of other uses, it can be used to remediate groundwater, purify contaminated drinking water, and even aid in air purification. …
Rotary kilns, like any other high-performing piece of equipment, need regular inspection and maintenance to ensure ideal operation. The list below highlights the areas of a kiln that should consistently be inspected: Refractory. Direct heat can cause the kiln’s refractory to become tremendously dry, and …
Today’s photo shows the interior of a batch rotary kiln. The photo was taken at FEECO’s Innovation Center in Green Bay, WI (USA), where we perform thermal tests on a variety of materials. Batch kilns are ideal for feasibility testing and defining process variables before …
Today’s photo highlights a batch rotary kiln in use at the FEECO Innovation Center. A chute, pictured left, carries the material to be processed, transporting it to the kiln’s interior. The two chords, or thermal couples, read the bed (material) and air temperatures during the …
This week’s photo shows the interior of an indirect-fired rotary kiln. Indirect kilns are used in various process settings where the processing environment must be tightly controlled, such as when processing materials that cannot be exposed to oxygen, or materials that must remain sterile, as …
