我厂是吉安地区一个电力调频厂,配有两台6000千瓦汽轮发电机组和两台35吨/时抛煤链条炉。由于我厂距各煤矿较远(都在60公里之外),故燃用煤种混杂。常用的三种燃煤是天河东区煤、萍乡煤、天河大井煤、其混煤特性详见表1。这三种混煤质差,发热量低,灰份大,挥发份少,给锅炉燃烧带来重重困难。当时地区用电紧张,发电任务重。我们为了烧好劣质煤,想了一些办法,采取一些措施,终于完成了烧煤任务,但也遇到了不少困难和教训。现将该炉烧劣质煤的体会作一介绍。 Our factory is a power frequency tuning plant in Ji’an area, equipped with two 6,000-kilowatt turbine units and two 35-ton / hour coal-throwing chain furnaces. Since I plant far away from the coal mines (all 60 km away), so burning coal mixed. The three commonly used coal is Tianhe Eastern coal, Pingxiang coal, Tianhe coal well, the coal blend characteristics shown in Table 1. The three mixed coal quality is poor, low calorific value, large ash, less volatile, burning boiler to bring numerous difficulties. At that time, electricity was in tension in the area and power generation tasks were heavy. In order to burn bad coal, we thought of some measures and took some measures to finally finish the task of burning coal, but we also encountered many difficulties and lessons. Here is the experience of the furnace burning inferior coal for an introduction.
