<p><P>PROBLEM TO BE SOLVED: To provide a method for producing quicklime/soft-burned dolomite, in which a gas fuel and waste plastics are burned as a main fuel and a sub-fuel, respectively, in a rotary kiln and by which the generation of coating in the rotary kiln can be suppressed. <P>SOLUTION: In the method for producing the quicklime/lightly calcined dolomite, a raw material is fired by burning the waste plastics being the sub-fuel together with the gas fuel being the main fuel in the rotary kiln. The waste plastics are charged through a main fuel burner 20 in which a waste plastic blowing-out port 21, a gas fuel blowing-out port 22, a blowing-out port 23 for an inner flow of primary air, and a blowing-out port 24 for an outer flow of primary air are each formed in the order of from the inside to the outside, and a main fuel burner 20 has a rotating blade is formed at the blowing-out port 23 for the inner flow of the primary air, and waste plastics is charged and burned via the main burner. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
