Emissions Testing of a Precalciner Cement Kiln at Louisville, Nebraska

摘要

The EPA is developing regulations to control emissions of products of incomplete combustion (PICs) from cement kilns. The emission parameters planned for use in this regulation are total hydrocarbons (HCs) and carbon monoxide (CO). To support the use of these parameters as surrogates for PICs, more information from full-scale testing of dry cement kilns is needed. As a part of this data-gathering effort, a test was conducted at the Ash Grove Cement Company precalciner kiln in Louisville, Nebraska.
