High temperature resistant measure is taken to extend its service life significantly in comparing with the tube still hot air furnace , whereas , cross brushing of heat sink by the smoke and negative pressure smoke exhaust are used to ensure a clean heat exchanging position with stable thermal performance 该炉采取了耐高温措施，从而使其寿命比列管式热风炉大大延长，并采用了烟气纵向冲刷散热片和负压式排烟方式，换热部分不积灰尘，无须清理，热性能稳定。
According to fuel and and operation condition in chongqing iron and steel group corporation , many kinds of advanced technologies are adopted , such as closed loop soft water circulation cooling , copper cooling stave , bell - less top with central charging hopper , carbon bricks combined furnace bottom with ceramic cup , russia top burner type hot air stove , duplex preheating of hot air stove , and nut coke charging 摘要根据重钢高炉的原燃料条件和操作条件，设计了重钢四高炉扩容性易地大修工程，采用了全软水密闭循环冷却、铜冷却壁、串罐式无料钟炉顶、炭砖陶瓷杯复合炉缸、俄罗斯“卡鲁金”顶燃式热风炉、热风炉双预热、焦丁入炉等先进技术。
Abstract : the distribution of cooling air which is in the grille - brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove . the influence of differential horizontal plates on the distribution of cooling air is discussed . the results show that original big circle round field of flow in the pillar - cavity is changed into full one - way field of flow and edges gas flow , at the same time , is increased by horizontal plates . there is a different function with horizontal plates and vertical plates . to make the uniform distribution of cooling air in the hot air stove , it is necessary that horizontal plates and vertical plates are used in a combined way 文摘:应用紊流三维数学模型模拟内燃式热风炉内冷风在格子砖柱中的分布，寻求改善其分布的途径.讨论了加设不同布置的水平导流板对气流分布的影响.模拟结果表明，在支柱空腔内加设水平导流板改变了原有大回旋流场，使回旋流变成大面积的单向流.通过在支柱空腔内加设水平导流板可以发展边缘气流，这恰好与加设竖直导流板的作用相反，水平导流板和竖直导流板的结合使用有望实现冷风在格子砖柱中的均匀分布
