    摘要： PROBLEM TO BE SOLVED: To provide a method for utilizing waste plastic in a burning furnace where chlorine consistency in a burnt product can be controlled to be low even when a chlorine-containing synthetic resin is included in the waste plastic when the burnt product such as quicklime, calcined dolomite and the like is manufactured by using the waste plastic as a fuel in the burning furnace such as a rotary kiln and the like. SOLUTION: When the burnt product is manufactured by heating a raw material in the burning furnace by the combustion of the fuel, the waste plastic including the chlorine-containing synthetic resin is used as a part of the fuel in the method for utilizing the waste plastic wherein blowing water or steam into the burning furnace is characterized. It is favorable that water or steam is blown with the combustion air of the fuel and so as to have a molar ratio of the blowing amount of water or steam to the blown amount of chlorine derived from the waste plastic of 1 or more.

    摘要翻译： 要解决的问题：提供一种在燃烧炉中利用废塑料的方法，其中即使在燃烧时废塑料中含有含氯合成树脂时，也可将烧焦产品中的氯稠度控制得较低 通过在诸如回转窑等的燃烧炉中使用废塑料作为燃料来制造诸如生石灰，煅烧白云石等的产品。 解决方案：当燃烧产物通过燃烧燃烧在燃烧炉中加热原料制造时，包括含氯合成树脂的废塑料在使用方法中用作燃料的一部分 特征在于将吹入水或蒸汽进入燃烧炉的废塑料。 有利的是用燃料的燃烧空气吹入水或蒸汽，使得水或蒸汽的吹入量与废塑料的吹出量的摩尔比为1以上。 版权所有（C）2008，JPO＆INPIT
