Glycerine byproduct from bio-diesel plants is used in a cement plant in Austria as a substitute fuel. This glycerine contains residual amounts of methanol, due to the production process. The fuel is stored in two horizontal tanks, which are equipped with hot-water heating. The pump installed adjacent to these tanks delivers the glycerine, heated to 30 to 50° C, firstly to a preheater and then to the burner of the calciner in the preheater tower. The more than 160 m long delivery line is fitted with trace heating. This combustion system was supplied by Unitherm Cemcon, of Vienna.
