Technological innovation points

① Applying the patented technology of dual outlet cyclone separator to cyclone preheater to reduce resistance loss;
② Innovatively transferring the experimental research on incineration of household waste in rotary kilns with current technology to incineration of household waste in pre decomposition furnaces outside the kiln, which can be applied to large-scale specifications, adjustable waste volume, stable calcination quality in rotary kilns, and pollution elimination, utilizing waste heat sources to achieve circular economy;
③ Connect heat-resistant steel bars in series with high insulation performance kiln lining to form an integral insulation layer, improve kiln stiffness, reduce deformation, and avoid brick dropping in the red kiln;
④ We have developed patented technology for circular heat exchangers around the kiln firing zone, which recovers and utilizes the radiant heat from the kiln body, reduces heat loss in the firing zone, and saves energy consumption of cooling fans around the firing zone;
⑤ Innovatively propose the comprehensive optimization and integration of the five components of large-scale rotary kiln calcination, including cyclone preheater, pre decomposition furnace, coal powder burner, rotary kiln, and cooling machine, using a computer intelligent control system.
