Title:
METHOD AND APPARATUS FOR PRODUCING QUICK LIME USING COKE DRY QUENCHING FACILITY
Document Type and Number:
WIPO Patent Application WO/2020/203629
Kind Code:
A1
Abstract:
Provided are a method and apparatus for producing quick lime using a coke dry quenching facility, whereby it becomes possible to produce quick lime with good thermal efficiency and in a simple configuration. A heated circulating gas that has been heated by cooling red-hot coke in a coke dry quenching facility is fed to a lime calcination furnace, and lime stone is thermally decomposed with the supplied heated circulating gas in the lime calcination furnace to produce quick lime. A cooled circulating gas that has been cooled by the thermal decomposition of lime stone and heat exchange with the lime stone in the lime calcination furnace is fed to the coke dry quenching facility and is used as a cooled circulating gas for cooling red-hot coke.
