沥青路面有时出现油包,严重影响交通。为了消除油包,过去采用煤球炉加热路面,然后再铲平,这样做效率低,成本高,烟熏火燎,劳动条件差,同时也有碍市容。我局河西区道路维修队经过反复试验,制成小型红外线沥青路面加热器,简称烤油包炉(见照片)。此加热器是以液化石油气为燃料,适用于沥青路面加热整修(烤油包)及路面接茬加热等,效果很好。构造红外线幅射器用薄钢板作外壳,燃烧网为双层铁铬铝丝金属网,外网规格为φ0.8
Sometimes the asphalt pavement appears oil packets, seriously affecting the traffic. In order to eliminate oil packets, in the past, briquettes were used to heat the pavement and then leveled, which was inefficient, costly, smoky, poor working conditions, and also impeded the appearance of the city. Hexi District Road Maintenance team after repeated tests, made of small infrared asphalt pavement heater, referred to as roasted oil furnace (see photo). This heater is based on liquefied petroleum gas (LPG) fuel and is suitable for heating and repairing asphalt pavement (roasted oil package) and heating on the pavement. The effect is very good. Construction of infrared radiator with a thin steel shell, the combustion network is double iron chromium aluminum wire mesh, the external network size φ0.8
