1 导热油加热沥青装置的选择我段于1988年4月开始筹建沥青砼拌和厂,选用 LB-30型沥青砼拌和设备.为了寻找与拌和设备相配套的沥青加温装置,我们先后赴甘肃、咸阳、西安、无锡等地,考察了远红外电热管加热沥青装置、蒸气锅炉加热沥青装置和导热油加热装置.经过反复对比分析,我们认为导热油加热沥青装置与其它装置比较,具有明显的优势,即安装简单,能作到当月安装当月使用;一次性投资较低,比蒸气锅炉加热装置低三分
1 HTF heating asphalt plant selection I paragraph in April 1988 began the construction of asphalt concrete mixing plant, the selection of LB-30 type asphalt concrete mixing equipment.In order to find and supporting the asphalt mixing plant equipment, we went to Gansu, Xianyang, Xi’an, Wuxi and other places, inspected the far-infrared electric heating pipe heating asphalt device, steam boiler heating asphalt device and HTF heating device.After repeated comparative analysis, we believe that HTF heating asphalt device compared with other devices, has obvious advantages , That is, the installation is simple, can be used to install the month of the month; one-time investment is lower than the steam boiler heating device three points lower
