带式炉褐煤提质工艺方法改性提质:在180~300℃温度范围内,褐煤受热脱除全水、结晶水和部分含氧官能团,褐煤脱氧改性,热值得到大幅度提升,成为高热值动力燃料。热解提质:在500~600℃温度范围内,褐煤热解,析出低热值挥发分,使固定碳富集,加工成为高品质的煤炭及煤焦油产品。三、带式炉特点1、薄煤层、大床面、低温大风量、气体热载体穿层加热,热交换强度高,快速连续生产,改性(热解)周期在60分钟之内,
In the temperature range of 180 ~ 300 ℃, lignite is heated to remove all water, crystal water and some oxygen-containing functional groups, the lignite is modified by deoxidation, the calorific value of lignite is greatly improved, and it becomes High calorific value fuel. Pyrolysis quality: In the temperature range of 500 ~ 600 ℃, lignite pyrolysis, precipitation of low calorific value of volatile matter, the fixed carbon enrichment, processed into high-quality coal and coal tar products. Third, the characteristics of belt furnace 1, thin coal seam, large bed, low temperature wind volume, gas heat carrier through layer heating, heat exchange strength, rapid continuous production, modification (pyrolysis) cycle within 60 minutes,
