25 Figure 3: PYROROTOR ® PYROCLON® Calcinedrs with Combustion Chamber for Utilization of coarse fuels with poor ignition and burning properties like coarse anthracite, Petcoke and coarse secondary fuels or waste derived fuels. The key features of KHD offered system are: • Utilization of coarse fuels with poor ignition and burning properties like coarse anthracite, Petcoke and coarse secondary fuels or waste derived fuels. • Ignition and start of combustion in pure air at high temperature (T > 1200°C). • Calcinedr retention time > 7 sec. • High efficiency and flexibility. • Lower demand on fuel quality and preparation efforts Figure 2: PYROCLON® Calcinedr – Table 2: Alternative Fuels Particle Size Range Description Heat Value [MJ/kg] PYROJET Kiln burner PYROCLON R Calcinedr PYROCLON R + Combustion Chamber Pet coke Anthracite ~ 33 Max. 5% R 90µm Max. 5% R 90µm Max. 10% R 90µm Fluff-RDF (2-D Material) ~ 18 0 – 30 mm 0 – 40 mm 0 – 100 mm (3-D Material) ~ 25 0 – 4 mm 0 – 5 mm 0 – 50 mm Waste Oil ~ 33 + + + Animal Meal ~ 17 < 20 % R @ 90 µm < 20 % R @ 90 µm < 40 % R @ 90 µm Dry Sewage Sludge ~ 9 Pulverized, mixed with coal dust + + Tire Chips ~ 32 - Max. 40 x 40 mm Max. 70 x 70 mm Biomass (shredded) ~ 15 0 – 4 mm 0 – 6 mm 0 – 50 mm PYROROTOR® is a rotary reactor that uses tertiary air as combustion air to process materials with inferior burning properties reliably as a secondary fuel for your cement production. Thanks to a direct drive, the combustion reactor enables constant material movement. Combined with adjustable rpm and long residence times, the PYROROTOR® enables complete burn-out of alternative fuels such as low-processed RDF, coarsest waste matter or even whole tires. With a PYROROTOR®, an unmatched level of flexibility for alternative fuels, paired with a significant potential for cost reduction can be achieved.
