Aside from being hazardous to our health, sulfur dioxide is one of the leading contributors in the formation of acid rain. Sulfur dioxide is produced in the burning of coal, often in utility plants. Coal, which naturally contains sulfur, mixes with oxygen during the burning …
In an article by Robert McCabe, McCabe details the issues arising with safely disposing of mounting fly ash. Fly Ash is a fine, powder-like material, resulting from the burning of coal at power plants. As power needs increase, so do these resulting leftovers. Unfortunately, this …
This is your opportunity to get into a great position in a family-oriented company. Founded in 1951, FEECO is an international business with a small business feel. FEECO International started out exclusively serving the fertilizer industry as a Fertilizer Engineering & Equipment Company. But over …
Previously, we looked at indirect fired rotary kilns in applications such as reactivating spent carbons, pulling valuable materials out of valueless carriers, and conducting thermal processes in inert environments. Now we will look at indirect fired rotary kilns in the application of processing finely divided …
Two innovative companies are working together, as Feeco International works with a company in Australia to solve a Soda Ash material problem. This company has developed processes that reuse the once unusable sludge resulting from desalination. Desalination is the process by which salt is removed …
Depending on the circumstances, indirect fired rotary kilns can have many advantages over direct fired rotary kilns. One such advantage is when the required thermal processing is best done in an inert atmosphere. As an example, most carbonaceous solids will combust when at elevated temperatures …
In the thermal processing industry, rotary kilns are used to cause chemical reactions or state changes in varying materials. As discussed previously in Direct Fired Rotary Kilns vs. Indirect Fired Rotary Kilns: What’s the Difference, while direct fired rotary kilns and indirect fired rotary kilns …
Whether a rotary drum is being used as a dryer, kiln, cooler, or otherwise, it is often a key process component in a production setting. As a result, downtime for the rotary drum can have the potential to hold an entire operation on idle. For …
Biogas has been a popular topic of discussion lately, as the need for energy increases, and sources are being run dry. Sometimes referred to as swamp gas, landfill gas, or digester gas, biogas is generated from anaerobic digesters such as animal manure, sewage, and municipal …
Rotary kilns are used to process a wide variety of materials, causing a chemical reaction or phase change. Within the rotary kiln industry, there are two major subsets: direct-fired rotary kilns and indirect-fired rotary kilns. Both kinds of rotary kilns employ the same thermal processing …
