High Efficiency - Reduced Emissions Boiler Systems for Steam, Heat, and Processing.

摘要

The demonstration of a cost effective solution to the problem of improving boiler efficiency and reducing emissions by means of a novel combustion control system and a sensor package was the main objective of this project. United Technologies Research Center and Fireye Inc., worked together to bring the new combustion control and monitoring system from Technology Readiness Level (TRL) 4 to TRL6 and demonstrate its effectiveness in a retrofit of the 30 year old Trane 25 MMBTU boiler at Watervliet Arsenal in NY state. During a one year testing campaign between February 2011 and March 2012, it was demonstrated that the new system would enable fuel savings of about 4% for typical utilization, and a corresponding reduction of CO2 emissions. The investment in the new technology on a similar boiler burning natural gas would pay back in slightly more than 2 years with expected fuel savings of $17,000 yearly. When adopted for all 10-100MMbtu/hr boilers older than ten year across DoD, the demonstrated technology has the potential to save $56 million of fuel costs annually, and avoid the emission of 600,000 tons of CO2.
