combustion supporting
1.It is convenient to preheat the coal gas and combustion-supporting air to the 1000℃.
2.TG/DTG-GC STUDY ON SULFUR-FIXING CHARACTERISTICS OF BRIQUETTE DURING COMBUSTION Ⅱ EFFECT OF SULFUR-FIXING/COMBUSTION-SUPPORTING AGENT ON COMBUSTIBILITY OF BRIQUETTE
3.The WC in the composite was produced from combustion reaction W+C=WC, in which (Al+CuO) was used as combustion-supporting reagent. The casting material was gray cast iron.
4.It could intensify and control the hot coal gas to have stable combustion by regulating the physical mixed process of hot coal gas and combustion-supporting air. Furthermore, it designs and develops the DGR type flame adjustable combustion equipment, suitable for the combustion of hot coal gas and it has the advantages of high combustion efficiency, high turndown ratio, safe and reliable operation. It has obtained the national patent.
5.The result of the experiments showed that when the content of combustion-supporting reagent was at the range of 5%~10%, the density of raw briquette was about 30%, the pouring temperature was at the range of 1450℃~1550℃ and the vacuum was about 0.04MPa, the Fe-WC surface composite can be produced on the gray cast iron .
6.Explosiveness of mixed gases is usually determined by three methods,namely,Coward explosive triangle method,explosive triangle calculation method adopted by U.S. Bureau of Mine and minimal combustion-supporting oxygen concentration method. However,how to get the analytical result visually,precisely and rapidly is very critical in disaster prevention and rescue.
