热风炉作为高炉正常生产的必备设备，为高炉提供着持续的高温热风，保证高炉

Blast stove as the necessary equipment to normal production, to provide sustained high temperature blast of hot air, to ensure that the combustion of the coke furnace by reduction of the iron oxides to metallic iron, directly affect the amount of blast furnace coke and coal injection, to reduce the cost of smelting It has an important significance. This paper describes the development stove, comparison of several common stove, stove understand the current advanced technology to analyze the program for 3000m3 blast furnace top combustion hot stove design.

As a necessary equipment for the normal production of blast furnaces, hot air furnaces provide continuous high temperature and hot wind for blast furnaces, and ensure that blast furnaces reduce iron oxides to metal iron through the combustion of coke, which directly affects the coke ratio and coal spray of blast furnaces, which is of great significance for reducing smelting costs. By introducing the development of hot air furnace, compare several common hot air furnaces, understand the current advanced hot air furnace technology, and analyze the design of the 3000m3 blast furnace top-burning hot-air furnace.
