Abstract
Recently, Refuse Derived Fuel (RDF) is focused on because of recycling wastes and reducing dioxin emission and so on. Tsukumi plant of Taiheiyo Cement Corporation is using RDF by Tsukumi-city as an alternative fuel and raw materials for the cement production. RDF includes high content of chlorine. It is important to analyze the chlorine content in RDF for the stable operation of the cement production, because the high content of chlorine exerts a bad influence on the cement production.
The aims of this paper are the establishment of analytical method for chlorine content in RDF and the estimation of chlorine content in RDF by Tsukumi-city with the method. The method was optimized, according to compare with existing analytical methods for chlorine content. And then, the chlorine content in RDF by Tsukumi-city was analyzed and estimated for each 8 weeks in winter and in summer in 1998. The results are as follows,
1) The analytical method for chlorine content in RDF has been established.
2) RDF by Tsukumi-city includes about 1wt% of chlorine.
3) The chlorine content in RDF by Tsukumi-city dose not show clearly the seasonal variation.
