The Research And Application On High Temperature Heat Accummlation Combustion In High Speed Mill Of YUZHONG STELL

High temperature heat accumulation combustion is a new concept of combustion technology,which was brought forward by 1980's.Compare with the traditional industrial furnace,it has the traits of high production rate,low fuel consumption and good in effect of security and environment protection.The application of accumulation heat furnace has not been widely used,so there are many problems about actual design still need to be discussed.Firsr,the selection of comnustion chamber burner,though the main principle are same ,the arrangement of burners aren't same ,so the combustion effect are different .Second ,the selection of the material ,the effect of accumulation heat and use life are different with different style and material of accumulatin heator .So here we put forward the ceramic accumulation heat ball as the first choice of the material of accumulation heat furnace,and the decentralization commutation combustion method ,which are all have the guide function for the selection and alteration of accumulation heat furnace.The reserch purposes of this task are the design and calculation of accumulation heat furnace ,we have made some particular demonstration and calculation of the selection of the accumulation heat material and the confirmation of the combustion system, confirmed the technology by introduction high temperature accumulation heat combustion technology into walking beam furnace,the equipment technology of this furnace reached the world advanced level, realized the purpose of resource saving, consumption decrease,environment protection long use life and high production efficiency.
