| GDRL-n closed hot air stacked towering furnace has four characteristics of "three heat interchanger", "reading style for wind," "automatic enriched devices", and "concentrated removal". The type towering furnace design is unique : innovative unit structure and allow for the wind means the wind beating confessions temperature reached 400 degrees, in coke ratio 1:10 conditions, the availability of high quality molten iron above 1500 degrees. This type towering furnce can obtain 50-100 degrees higher temperature than ordinary towering furnace, saving more than 20% of coals; Using closed ground removal system, the towering furnace solve pollution problems; Small heat interchanger prolongs using life. GDRL-n closed stacked blast heating towering furnace construction, maintenance convenience, the National Press Mechanical Quality Testing Center for fostering 5t/h stoves six projects testing, the standards require that all targets were met, and the towering furnace manufacturing performance fine. In the use of ordinary metallurgical Bellagio, layer coke ratio 9-10, molten iron temperature stability in 1480-1490 degrees centigrade, life expectancy has more than 4,000 small wind guts hours, reaching domestic advanced level. The successful development of GDRL-n closed hot air stacked towering furnace truly achieve "high-temperature, section focus, quality, low-emission" high-tech. Currently, GDRL-n type closed hot air stacked towering furnace has worked to promote the success of dozens of provinces and cities throughout the country, many users have been chosen and significant economic and social benefits achieved. |
