2. Description of the Related Art In a cement plant, as shown schematically in FIG. 2, a rotary kiln-type firing furnace (rotary kiln 1) is used.
A cyclone type preheating device (suspension preheater 2) for preheating raw materials with exhaust gas from a rotary kiln, and a kiln with a new suspension preheater (NSP kiln) provided with a calciner 3 between the preheater and the rotary kiln Mainly used. This NSP kiln is a system in which 50 to 60% of the required fuel is burned in a calciner 3 to efficiently promote the decarboxylation reaction of the powdered raw material and feed it into the kiln. The apparent decarbonation rate is high, the specific firing capacity is more than twice that of SP kiln and the productivity is high. (2) Only 40 to 50% of the required fuel on the kiln side is fired, so the heat load of the firing zone (3) The calciner outlet gas temperature is relatively low (for example, 850 to 900 ° C.), and the amount of generated NOx is small.

In such an NSP kiln, when a cement material is introduced into an inlet of a cyclone-type heat exchanger (hereinafter simply referred to as a cyclone) at the uppermost stage constituting a suspension preheater, the introduced material becomes exhaust gas and heat in the cyclone. It is centrifuged while exchanging, and falls downward from the lower end of the inverted cyclone at the bottom of the cyclone. The raw material is further supplied to the lower cyclone inlet gas flow path, and enters the cyclone with the gas and is centrifuged. In this way, the raw materials are sequentially transferred to the lower cyclone while being heated by the exhaust gas, finally calcined in a calciner, and supplied to the rotary kiln from the lower part of the lower cyclone again.
