State map facts sheets stress the contribution of the cement and concrete industries to the state and local economy Use them for outreach to public officials and in local and federal advocacy In addition to maps showing cement and concreterelated facilities across the state they also highlight local issues such as the need for
the portland cement kiln system Sulfur in cement kilns is derived from both kiln feed and kiln fuel The form of the sulfur dictates the location in the kiln where the SO2 generation takes place Sulfur in the fuel is oxidized in the burning zone or calciner and is easily removed by reactive lime present in the kiln

Portland Cement Kilns 6 Emissions The quantitative rate of releases of air contaminants to the atmosphere from an emission point as measured by the Continuous Emission Monitoring System source tests or as calculated by the methods specified in
Cement is a finely ground powder which when mixed with water forms a hardening paste of calcium silicate hydrates and calcium aluminate hydrates Cement is used in mortar to bind together bricks or stones and concrete bulk rocklike building material made from cement aggregate sand and water
cement and lime kilns have been combined into one category For oilfired home heating oil the only control option considered is reduction in sulfur content in the fuel oil In addition to the analyses conducted on source categories analyses are presented for 50 specific sources 30 EGUs 17 ICI boilers and three cement kilns
Cement kilns have been identified as a stationary source that emit more than 25 tons of nitrogen oxides NO x per year This alternative control technique ACT document provides technical information for use by State and local agencies to develop and implement regulatory programs to control NO x emissions from cement kilns
burners in a cement kiln Staging of combustion air as achieved by such burners is a possible technique for NO x reduction in cement kilns In the first stage fuel combustion is carried out in a high temperature fuelrich environment and the combustion is completed in
The product called clinker from the kiln is cooled ground and then mixed with a small amount of gypsum to produce portland cement The main source of air toxics emissions from a portland cement plant is the kiln Emissions originate from the burning of fuels and heating of feed materials

Depending on the process 3565 of the production cost is for fuel A typical wet process cement kiln may burn about 150 tons 140 X 103 kg of coal a day to provide approximately 35 billion Btus 3700 GJ of heat A cement kiln may be 1015 ft 346 m in diameter and 350500 ft 107152 m in length
The base year emissions inventory was projected to 2007 by applying scalar growth factors for most source categories Each LADCO State provided estimates of source growth and control factors by source sector Source growth and emission control factors used in EPAs NO X SIP Call were also considered particularly for EGUs Table 1 of the LADCO
