Inquiry (采购产品): Cost estimate for SO2 CEM Hello, I work for the Cleveland Division of Air Quality and we are currently working on a permit for a facility that processes raw shale in a kiln. The facility is proposing to burn coal in the kiln to help save on fuel costs. We are interested in obtaining some general cost estimates for installing an SO2 CEM. This facility is already required to install a Continuous Opacity Monitor (COM) per USEPA regulation. It is our understanding that the cost for adding the SO2 CEM should be reduced since the installation of the COM already addresses things such as available port and energy source. The existing rotary kiln will use coal as the primary fuel and will use low-NOx burner or equivalent technology. The kiln has a 45 tons/hr capacity used for the production of expanded shale. The kiln will also be equipped with a baghouse to control PE, PM10, Pb, Hg, As, Cd and Cr emissions. A lime slurry injection system is employed to control SO2, HF and HCl emissions via the same baghouse. In addition to coal, this emissions unit also uses re-refined used #4 fuel oil and/or natural gas as backup fuels. The allowable SO2 emission rate proposed for this project is approximately 270 lbs SO2/hour and 822 tons SO2/year. If possible, please provide some average or general costs associated with the installation of an SO2 CEM for a system that will already be equipped with a COM. We need to resolve this issue soon so a timely response will be appreciated.
