Yet another application for biochar looks to be on the horizon; a growing number of studies are proving that biochar could be an effective tool in managing air quality, with one study finding that the charcoal-like material has the potential to significantly reduce air quality-related …
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) …
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: Prevention is key when it comes to maintaining a rotary kiln. Regularly inspect …
