Inquiry (采购产品): Heater Retrofit Barry Weiner: Barry, I am doing some air permitting work for SemMaterials and would like to get some information regarding retrofit of a hot oil heater. Mike Sattler of SemMaterials asked me to contact you. We have a heater at the Billings, MT facility that is 10.5 MMbtu/hr heat input (model number AHE650). The state has asked us to do a BACT analysis for the heater. Can you give me rough cost estimates for installing low-NOx and ultra low-NOx burners on this unit? I'd also like to get the mass emission levels (e.g. lb/hr or lb/MMBtu) that each type of burner would provide for NOx and CO. Thanks for you help on this. **** Hidden Message ***** Emmett Keegan 60526 USA Company: VBA Compliance Assurance Phone: 708-352-3811 E-mail: vbaekeegan@aol.com **** Hidden Message ***** vbaekeegan@aol.com
