June 30, 2009 - Emerson Process Management has enhanced its Rosemount Analytical OCX8800 oxygen and combustibles transmitter to offer advanced functionality and reliability in coal-fired applications, helping to improve burner efficiency and reduce nitrogen oxide (NOx) emissions. Featuring oxygen and combustibles measurement capabilities in a single design, the new OCX8800 boasts an improved sensor technology that reduces drift. It is the first transmitter of its kind to support FOUNDATION fieldbus communications.Adaptable to any oxygen and combustibles installation, the enhanced OCX8800 is NEMA 4X rated for weather resistance, corrosion resistance and is rated as explosion-proof.
The device can be configured for general purpose installations or it can be configured for hazardous area locations in which CSA/FM Class 1, Zone 1 ATEX II 2 G EExd and IECex ratings are required.The proprietary software also includes new features that minimize COe cell degradation for improved reliability with fewer calibrations. And for added flexibility, the OCX8800 supports FOUNDATION fieldbus and HART communication. The transmitters are part of Emerson’s broad range of intelligent, digital field devices that power the PlantWeb architecture.
Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the transmitters are integrated into the PlantWeb digital plant architecture.The OCX8800 is easy-to-install with no electronics box, probe cable or conduit, and features a universal power supply for automatic line-voltage selection. Integral or remote-mounted electronics options are also available. “Until now, coal-fired facilities had an unmet need for reliable oxygen and combustibles data because environmental conditions prohibited the supply of information,” said George Keeler of Emerson’s Rosemount Analytical 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.”
