SLHB型双滚筒沥青混凝土拌和机,由于其配置的煤粉燃烧装置具有许多优点,因而颇受公路工程部门的欢迎,主要是与烧柴油相比,烧煤粉可以节约燃料费用。近年来,我们单位购置了多台这种拌和机,在筑路施工中发挥了比较好的作用;但如果没有掌握正确的使用和维护煤粉燃烧装置的方法,不但难以取得预期的节约效果,还会引起作业不稳定、排气冒黑烟而污染环境等问题。根据我们的实践经验,现就煤粉燃烧装置的使用和维护知识做下述简单介绍。 SLHB double drum asphalt mixing machine, due to its configuration of the pulverized coal combustion device has many advantages, so popular with the highway engineering department, mainly compared with burning diesel, burning coal can save fuel costs. In recent years, our unit purchased more than one such mixer, which has played a good role in the road construction. However, if we do not have the proper method to use and maintain the pulverized coal combustion unit, it is not only difficult to achieve the expected saving effect, Will also lead to job instability, exhaust black smoke pollution of the environment and other issues. Based on our practical experience, the following brief introduction is given on the use and maintenance of pulverized coal combustion units.
