The invention discloses a process for feeding sludge into a furnace by adding a stepped preheating process. The process comprises the following steps: A, conveying sludge; b, sludge enters a kiln tail step pre-combustion furnace through an air locking system; c, pre-burning the sludge by a stepped pre-burning furnace; d, flue gas obtained after incineration and small-particle sintering slag enter a decomposing furnace, and organic components continue to be decomposed or cracked through the decomposing furnace; e, a small amount of large-particle sintering slag falls into the rotary kiln from the uptake flue at the tail of the kiln and then is calcined into cement clinker through a rotary kiln system.The sludge treatment process is easy to operate, good in environmental protection performance and sufficient in sludge combustion, meanwhile, smoke can be thoroughly filtered, and harmless treatment of the sludge can be achieved; the stepped combustion platform is adopted, sufficient combustion ...
