Technology and engineering company Emerson has launched an in-situ oxygen analyzer which is designed to improve the energy efficiency for small and midsize boiler markets and also meet environmental regulatory requirements.

The US-headquartered company says the Rosemount CX1100 is the first high-performance, zirconia cell-based combustion control system designed for flue gas measurement for these users.

“Midsize and small boiler users need a system that provides a high level of measurement reliability but justifying the costs and complexity of industrial combustion systems can be a challenge,” said Peter Lagerlof, vice-president for liquid and combustion analysis products at Emerson Automation Solutions.

“Our customers have requested a system that is right-sized for their needs – one that provides the performance they need without incorporating features the smaller end user doesn’t require.”

With increasing environmental requirements, users of light industrial and commercial boilers are faced with escalating compliance demands that increase the need for measurement and control of the fuel-air ratio, which optimises energy efficiency and reduces emissions.

Many small to midsize boiler users currently do not measure oxygen in combustion flue gas, leaving themselves open to regulatory as well as energy inefficiency problems.

Enerson said that with the Rosemount CX1100, “it is now economically feasible to bring high quality and repeatable zirconia technology to these markets”.

“The lifespan of the sensor resulting from the zirconia sensing cell and the all-welded probe gives users and OEMs the quality and reliability they need,” said Lagerlof.

“At the same time, the system offers an easy-replacement design that enables simplified post-warranty service. The combustion control system requires no reference gas, which keeps installation and maintenance costs low”.
