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. …
Rotary dryers are sized and designed around a material’s unique processing needs, or at least they should be. A custom rotary dryer will produce the most ideal results. The following material characteristics should be considered in sizing and designing a dryer: Moisture content, including inlet …
As traditional bedding options become increasingly unreliable, more farms are looking to Recycled Manure Solids (RMS) or Dried Manure Solids (DMS) as an alternative bedding material for livestock. Ongoing research and the number of farms successfully utilizing this approach have proven that both recycled and …
Rotary dryers are known as the workhorses of the industrial drying industry, but like any robust equipment, they are not immune to processing challenges. The challenges often vary on the specific material being processed, with some requiring additional preparation, and others, routine maintenance. Generally speaking, …
As large farms become the future of agriculture, the need for sustainable solutions in managing manure is becoming an ever-increasing focus. However, while large farms are learning to deal with the amount of manure they produce, significant opportunity lies in processing manure to produce products …
Various data points are measured during the rotary dryer feasibility tests conducted in FEECO’s Innovation Center, with the most common being: Inlet and outlet moisture content of the material. Inlet and outlet material temperature. Material feed rate. Residence time. Inlet process air temperature. Outlet gas …
This week’s photo features two lifter designs. Lifters, also known as fins or flights, are commonly added to the interior of a rotary dryer to assist in the industrial drying process. Their overall objective is to promote efficient heat transfer between the material and the …
