Abstract
The invention relates to apparatus for producing fired bulk material, particularly cement clinker, wherein the bulk material is first fired and then cooled. The cooling of the hot bulk material takes place by gasification of a fuel, particularly coal, with steam, the reaction enthalpy necessary for the gasification reaction being extracted from the hot bulk material. In this gasification a fuel gas is also produced which is used for firing the bulk material.
Claims7
In apparatus for producing fired bulk material having a rotary kiln for firing said material, a cooler connected to said kiln for receiving hot material from said kiln and cooling said material, first means for delivering fuel to and mixing said fuel with the hot material, and second means for passing steam into the mixed material and fuel to effect a gasification reaction and extraction of reaction enthalpy from such material, the improvement comprising a reactor mounted on said kiln and containing said first and second means.
