我车间有两座90M~3混凝土竖窑,70年正式投产,每座窑日产石灰65吨。自生产以来,烧石灰石的燃料一直采用粉煤。开始,我们碰到很多困难。如石灰石和粉煤的配比掌握不准,烧出的石灰不是老,就是生。我们按照粉煤的发热量为6600～6200大卡/公斤,以及石灰石分解成石灰时吸热42.5大卡/公斤计算得烧100公斤石灰石需7公斤粉 I have two workshops 90M ~ 3 concrete shaft kiln, 70 officially put into operation, each kiln daily lime 65 tons. Calcined limestone fuel has been pulverized coal since its production. At first, we encountered many difficulties. Such as the ratio of limestone and pulverized coal is not allowed to control the burning of lime is not old, is raw. We are in accordance with the calorific power of pulverized coal 6600 ~ 6200 kcal / kg, and when limestone absorbs 42.5 kcal / kg when lime is decomposed into lime Calculated 100 kg of limestone required 7 kg of powder
