Oxygen and combustibles transmitter for coal-fired boilers
Enhanced sensor technology in Rosemount OCX8800 transmitter provides data to support emission reductions and burner efficiency improvements.
Emerson Process Management has enhanced its Rosemount Analytical OCX8800 oxygen and combustibles transmitter to offer advanced functionality and reliability in coal-fired applications, providing data to help improve burner efficiency and reduce nitrogen oxide (NOx) emissions.
With oxygen and combustibles measurement in a single design, Emerson says the new OCX8800 uses an improved sensor technology that reduces drift. Plus, it is the first transmitter of its kind to support Foundation fieldbus communications.
"Until now, coal-fired facilities had an unmet need for reliable oxygen and combustibles data because environmental conditions prohibited the supply of information," says George Keeler of Emerson's Rosemount process analytic division. "The rugged design and new sensor technology of the OCX8800 has finally made it possible to achieve stable and reliable measurements under many coal-fired conditions. Access to this data helps operators fine-tune the fuel-to-air ratio and minimize NOx emissions by properly monitoring burner performance."
Adaptable to a wide range of oxygen and combustibles installations, the device is NEMA 4X rated for weather resistance, corrosion resistance, and is explosion-proof. It can be configured for general purpose installations or hazardous area locations with CSA/FM Class 1, Zone 1; ATEX II 2 G EExd; and IECex ratings.
The proprietary software includes new features that reportedly minimize COe cell degradation for improved reliability with fewer calibrations. For networking flexibility, the OCX8800 supports Foundation fieldbus and HART communication.
