3.1、生產方法、規模及產品性能Production method, scale, and product performance

    3.1.1工廠生產方法：本項目采用天然氣作為燃料，采用帶豎式預熱器、豎式冷卻器的回轉窯煅燒系統生產線。Plant production method: the project uses natural gas as the fuel, and adopts the rotary kiln calcining system production line with vertical preheater and vertical cooler.
    3.1.2工廠建設規模：見表 3.1Plant construction scale: see Table 3.1
表 3.1 工廠建設規模及產能
Table 3.1 Plant construction scale and production capacity
 

      （1）年工作時間：330 天Annual working hours: 330 days
      （2）單位產品熱耗Thermal consumption per unit product：石灰lime≤1200kCal/kg  ，單位產品石灰石料耗Limestone material consumption per unit product：≈1.78kg/kg 石灰lime
      （4）產品粒度組成：活性石灰約塊灰 Block lime 80%、粉灰 pulverized lime  20%。
     （5） 除塵有組織排放含塵濃度指標
Dust content concentration index of dust removal：＜10mg/Nm3
    3.1.3物料運輸方式：石灰石由汽車運輸至原料儲存庫，天燃氣運輸到廠區外紅線一米處；成品通過成品庫散裝裝車后汽車輸送給各用點。Material transportation mode: limestone is transported from the truck to the raw material storage warehouse, natural gas to the red line outside the factory; the finished product is transported to the use points after bulk loading through the finished product warehouse.
