An important consideration in rotary kiln design is air flow, or the direction in which the process gas moves through the kiln in relation to the material. The cross-flow configuration is specific to indirect-fired rotary kilns. Here, the material and the process gas flow perpendicular …
Drought is becoming a rising concern across the world as water scarcity, changing climate patterns, and the need to feed a growing population continue to dominate the landscape of pressing global issues. As such, the need for soils to be capable of withstanding drought conditions …
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) …
This week’s photo highlights a rotary dryer combustion chamber from FEECO’s Fabrication Facility. In regards to rotary dryer components, the combustion chamber houses the combustion reaction. From here, the drying air is directed through the rotary drum. FEECO offers a variety of combustion chambers including …
This week’s photo shows a combustion chamber under production in FEECO’s Fabrication Facility. Castable refractory is pictured in the center. Fiber modules surround the castable on either side; they are lighter and have a lower thermal conductivity. The fiber modules are not used on the bottom …
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. …
