A pyrolyzer-kiln system for generating combustible fume from waste material and supplementing the fuel used to provide heat energy to a clinker kiln. The system includes a pyrolyzer for generating a combustible pyrolytic fume, a kiln for burning the fume as part of a cement-forming process, a conduit for conveying the fume from the pyrolyzer to the kiln, and a closed-loop feedback component for monitoring the heating value of the fume and varying the operational parameters of the pyrolyzer to maintain the heating value of the fume generated within a predetermined range. The closed-loop feedback component includes a calorimeter which continuously samples and burns fume from the conduit. The heating value of the fume is determined by measuring the amount of auxiliary fuel and air required to be mixed with the fume to maintain a predetermined temperature when the combustion is burned within the calorimeter. Controllers monitor the amount of auxiliary fuel and air supplied to the calorimeter and vary the temperature within the pyrolyzer to effect an increase or decrease in the heating value of the fume. The system also includes a burner pipe for injecting the fume into the kiln which has a variable orifice to maintain a constant pressure differential across the orifice and thereby maintain a predetermined flame shape as the fume is burned in the kiln.
