一、热风炉工作原理简介热风炉主要是向高炉提供一定温度和一定量的热风,以降低高炉焦比。热风炉的工作分燃烧期和送风期,从燃烧转为送风,从送风转为燃烧,中间都存在一个换炉过程。在燃烧期,用燃料加热炉内的格子砖,这是一个蓄热的过程;在送风期,就靠炉内的格子砖的热量,把鼓风机送来的冷风加热到1000℃以上再送往高炉,这是一个散热过程。换炉时间通常用以下方法来确定: (1)定期换炉:给定送风时间,到时间就换。 (2)定废气温度换炉:当热风炉燃烧时,其烟道废气温度达到规定的上限就换炉。 (3)按最佳热效率换炉:根据风温、风
First, the principle of hot stove Brief introduction Hot stove is mainly to provide a certain temperature to the blast furnace and a certain amount of hot air, in order to reduce the blast furnace coke ratio. The work of hot blast stove points combustion period and air supply period, from combustion to air supply, from air supply to combustion, there is a middle of a furnace process. During the combustion period, the furnace is heated with a piece of checkered bricks, which is a heat accumulating process. During the blasting period, the cool air from the blower is heated to above 1000 ° C by the heat of the bricks inside the furnace. Blast furnace, this is a cooling process. Furnace time is usually determined by the following methods: (1) regular furnace replacement: given the time of the air, to the time to change. (2) set the exhaust gas temperature change furnace: When the hot stove combustion, the flue gas temperature reaches the prescribed upper limit on the furnace. (3) According to the best thermal efficiency furnace: According to the wind temperature, wind
