1概述当前我国中小型轧钢加热炉的能源仍然是以煤为主，把人工加煤的轧钢加热炉改造为燃煤粉是减轻工人劳动强度和节能的一项重要措施。烧煤粉可以实现自动控制，而国内大多数这种加热炉与人工烧煤时一样，缺乏必要的检测仪表，调煤不调风，不是燃烧不完全就是风量过大，使烧煤 1 Overview At present, the energy of small and medium sized steel rolling reheating furnaces in our country is still based on coal. It is an important measure to reduce the labor intensity and energy saving of workers by converting artificial steel rolling furnaces into pulverized coal. Burning pulverized coal can be automatically controlled, while most of the domestic heating furnace and artificial burning the same as the lack of the necessary instrumentation, adjusting the coal does not adjust the wind, either incomplete combustion is the air volume is too large, so that coal
