热风炉是高炉正常生产必备设备，一般一座高炉配备3~4座热风炉，可为高炉

Normal production of blast furnace hot stove of the necessary equipment, generally with a blast furnace hot stove of 3 to 4, can provide sustained high temperatures of greater than 1000 ℃ hot blast of hot air into a blast furnace hot stove provided the total amount of heat energy BF a quarter, a direct impact on the economic costs and the amount of pulverized coal injection in the blast furnace. This article describes the blast air supply system, comparing the internal combustion type hot, and external combustion hot stove top combustion hot stove, and analyzes their characteristics, advantages summarized with respect to 3000m3 furnace where combustion hot stove top.

热风炉是高炉正常生产必备设备，一般一座高炉配备3~4座热风炉，可为高炉提供持续的大于1000℃的高温热风，热风炉所提供的热风带入高炉的能量占高炉总热量的四分之一，直接影响着喷煤量以及高炉的经济成本。本文介绍了高炉送风系统，比较了内燃式热风炉、外燃式热风炉和顶燃式热风炉，分析其各自的特点，总结出对于3000m3高炉配备顶燃式热风炉的优势所在。

The hot blast furnace is the necessary equipment for the normal production of blast furnace. Generally, a blast furnace is equipped with 3-4 hot blast furnaces, which can provide the blast furnace with high temperature hot blast of more than 1000 ℃ continuously. The energy brought into the blast furnace by the hot blast furnace accounts for one quarter of the total heat of the blast furnace, which directly affects the coal injection and the economic cost of the blast furnace. This paper introduces the blast furnace air supply system, compares the internal combustion hot blast furnace, external combustion hot blast furnace and top combustion hot blast furnace, analyzes their respective characteristics, and summarizes the advantages of top combustion hot blast furnace for 3000m3 blast furnace.
