Burner lines and Positive displacement pump

These lines are made of copper and their diameter is about 230mm. These lines carry the hot compressed air inside the tanker. These lines help to exchange the heat of these gases with the bitumen inside the tanker. The bitumen takes heat from these copper lines and thus fails to stick over the surface and remains in liquid state, the hot bitumen reduces its density after heating and thus its space is taken by cooler bitumen, in this way cycle continues and the bitumen remains in hot condition.

Positive displacement pump is also called bitumen pump which is used to empty the tank and also provide bitumen under pressure(6kg/cm2) to the spray bar consisting nozzles for spaying bitumen on road. It is 2’’ X 2’’ gear pump with output of 350LPM.
