一、前言BL-30型沥青混凝土拌和机拌和仓的供热系统原设计是由一台锅炉提供热汽,而我站根据建厂的实际情况,经考查选用了安全、经济、可靠的QXG-60导热油加温沥青装置。经过分析测算尚有余力提供热源保证拌合机的供热。我们自力更生,大胆科学地进行了设备改造,经反复分析论证,成功地完成了利用导热油加温装置与沥青混凝土拌和机配套应用的试验。现将情况介绍如下: I. INTRODUCTION The original design of heating system of BL-30 asphalt mixer mixing plant is provided by a boiler to supply steam. According to the actual conditions of the plant, the station chooses a safe, economical and reliable QXG- 60 HTF heating asphalt plant. After analysis and calculation there is still spare capacity to provide heat to ensure mixer heating. We are self-reliant, bold and scientific equipment transformation, after repeated analysis and demonstration, the successful completion of the use of HTF heating device and asphalt mixing plant supporting the application of the test. Now the situation is as follows:
