高效节能高风温大型球式热风炉的开发应用与热平衡测定

Development and application of large sized pebble hot air stove featuring high efficiency,energy saving and high hot air temperature and thermal balance determination

对柳钢6号高炉(750m3)高效节能高风温大型球式热风炉的开发应用及热平衡测定进行了总结。通过采用大型无焰陶瓷燃烧器、刚玉质耐火球等新技术、新设备、新材料,解决了球式热风炉大型化的一些制约因素,在使用单一高炉煤气的条件下,获得1430℃的顶温,最高风温达1250℃。目前,该技术已应用到柳钢7号高炉(1080m3)、8号高炉(1280m3)。

Successful development and application of large sized pebble hot air stove featuring high efficiency, energy saving and high hot air temperature for No. 6 blast furnace(750 3) in Liuzhou Iron and Steel Group Co. is summed. Adoption of new technology, new equipment and new material, such as high duty flame free ceramic burners, and corundum ball refractory make the large sized pebble hot air stove free from various restriction factors, the hot air stove can reach 1430℃ dome temperature while using 100% blast furnace gas and the max hot air temperature can be as hot as 1250℃. Nowadays, this technology has been applied in No. 7 blast furnace(1080m 3) and No. 8 blast furnace (1280m 3) of Liuzhou Iron and Steel Group Co.
