Title:
THERMAL DECOMPOSITION METHOD
Document Type and Number:
Japanese Patent JPH10225668
Kind Code:
A
Abstract:
To efficiently fix a chlorine component discharged into thermal decomposition gas with thermal decomposition of a waste product with a simple means.
In a waste product treatment equipment having a thermal decomposition device for thermally decomposing the waste product, at least one kind among Ca(OH)2, CaO and NaOH is preliminarily added to the waste product and is charged into the thermal decomposition device and is retained for more than 10mins. in a range of 250-300°C, and then is heated at 400-800°C in the same thermal decomposition device to obtain a thermal decomposition product.
