Properties and Performance of Carbonized Corn Straw as Thermal Insulating Agent of Liquid Metal

Owing to the status that the price of thermal insulating agent for liquid metal has been raising constantly in recent years, the present work investigated the properties of carbonized corn straw using as thermal insulating agent of liquid metal. The results showed that the carbonized corn straw possessed higher content of fixed carbon, smaller repose angle (or better flowing property) and lower heat conductivity coefficient compared to carbonized rice husk. Both the laboratory test and practical application of using carbonized corn straw as thermal insulating agent of liquid metal showed that it had a better thermal insulating performance, whereas a bigger collapse ratio and agglomeration were found. Thus, a satisfied application performance of thermal insulating can be achieved by using a mixture of carbonized corn straw and carbonized rice husk. The application of carbonized corn straw as thermal insulating agent of liquid metal not only develops a new effective way to use corn straw, but also contributes to decrease the production cost of metallurgical industries.

Nanoparticle recovery using a fume collector comprised of carbonized refuse-derived fuel

A breakthrough use of refuse-derived fuel (RDF), i.e., as a dust/fume collector, is proposed in this article. In the experiments, RDF was first carbonized under different thermal conditions and then its ability to recover nanoparticles was studied using thermogravimetry with a gas analyzer, and compared with other carbonaceous materials for cleaning combustion waste gas. The recovery property of various samples was monitored by suing smoke of joss stick, with a size of 400 nm. As a result, due to its unique structure, carbonized RDF was observed as being the most effective for recovering the particles among various samples. The filtering property of carbonized RDF significantly depended on the thermal conditions followed during carbonization. Its recovery property was improved when it underwent preheating for a shorter period of time and at a higher carbonizing temperature. These results present the possibility of carbonized RDF being used as an efficient nanoparticle collector. This study was initiated to examine whether carbonized RDF can be used as a packed material for recovering fine iron powder generated in an electric arc furnace (EAF).     

Sintered porous balls from rice husk for thermal insulation in iron and steel industries

Sintered porous balls were prepared from waste rice husk (RH) for thermal insulation purposes on the top of the ladles and tundishes in iron and steel industries. As the permanent insulating structure is not possible, temporary insulation is done by using agricultural wastes for economy that burn out and produce porous ash-based insulating layer. But the layer formed is non-uniform in thickness, causing non-uniform cooling pattern of the stored steel and variation in properties. Also burning of the wastes causes various occupational health hazards. Reduction in health risk with uniform insulating layer thickness could be achieved by using the temporary insulation as a sintered porous ball. Such a developmental work is described here using RH as the starting material. Ash generated is mesoporous in characteristic giving insulating properties; sintered form does not allow any fly off thus controls pollution and health hazards; and the ball shapes will result in uniform spreading with a uniform thickness of insulation.

Use of substrate-coated barium sulfate tablets in the evaluation of digestive enzyme deficiency

Glucose solution containing wheat straw hemicellulose-B and ovoglycopeptide (W-O-G) has no effect on Ehrlich ascites tumors but completely regresses Ehrlich solid tumors. The carcinostatic effect of this mixture is lost or decreases markedly whenever one of the three substances is lacking. For this glucose solution to possess a carcinostatic effect it is necessary that this hemicellulose-B of W-O-G is the hydrolysate of the extract with 20% NaOH from the residue obtained after extraction of wheat straw with 10% NaOH.
