PRODUCTION OF QUICKLIME-CALCINED DOLOMITE IN ROTARY KILN USING WASTE PLASTICS

摘要

PURPOSE: To provide a production method of quicklime and calcined dolomite by efficiently burning waste plastics in a rotary kiln. CONSTITUTION: This production method is provided with a process (a) for making waste plastics to a small bundled stream as a portion of a fuel during the production of quicklime and calcined dolomite with a rotary kiln, and (b) a blowing process (b) for blowing both a fine flux flow of the waste plastic particles and main fuel into the rotary kiln so that at least a portion of the fine flux flow crosses a flame of the main fuel and also a falling point of unburned waste plastic particles in the rotary kiln becomes within a distance of the flame length of the main fuel.
