    摘要: A combination of a dehydration process for dehydrating sewage sludge by mixing a quicklime-containing material with the sludge, a cement conversion process for introducing the solids produced by the dehydration process into a cement kiln with other cement raw materials to yield cement, and a gas treatment process for introducing gases generated in the dehydration process into a cement burning process, thereby enabling conversion of the sewage sludge into cement without releasing wastes, with a reduction in fuel consumption for the cement burning, and a reduction in NOx content of the exhaust gas.

    摘要: A method and an apparatus is disclosed for producing such as Portland cement from pulverant raw material in a system having at least a preheater and a rotary kiln. The preheater may be of the type having a series of stages each provided by a cyclone dust separator for successively preheating the raw material in a counterflow of kiln waste gases and in which an identified one of the stages discharges a gas flow containing more thermal energy than can be used to advantage in preheating material in the remaining stages through which such gases must pass before dispersing in the surrounding atmosphere. A portion of the gases passing from the identified stage is diverted to a heat exchanger which utilizes the heat energy in such kiln waste gases to heat a clean stream of air. The thermal energy transfer to clean heated air is in turn delivered to the kiln and/or an auxiliary furnace connected to discharge into the kiln waste gas flow between the kiln and the identified stage, and such delivery of clean heated air provides heated combustion air for the burning of fuel in the kiln and/or auxiliary furnace.
