X-STREAM® Oxygen Analyzer's extended, adjustable probe length enables more accurate readings for large boilers and furnaces
 |
SOLON, OHIO (August 7, 2008) – Emerson Process Management has enhanced its Rosemount® Analytical X-STREAM® Oxygen Analyzers to improve efficiencies of large boilers and furnaces and provide immediate reduction of carbon dioxide (CO2) emissions with minimal investment.
Large industrial boilers and furnaces are primary generators of the greenhouse gas CO2. Rosemount Analytical X-STREAM O2 in situ combustion flue gas analyzers are a key tool for optimizing combustion, and reducing emissions. These analyzers provide information to control the fuel-to-air ratio of the burner, much in the same way it’s done on today’s automobiles. The X-STREAM O2 probe now offers improved AccuMax™ accuracy specifications, extended temperature capability, and new longer probe lengths up to 18 feet long to satisfy the need of the industry’s biggest boilers and furnaces.

According to Doug Simmers, worldwide product manager for Rosemount Analytical, large furnaces will typically have many burners delivering fuel and air into the combustion zone, which may be the size of a 10 story office building. Balancing the burners maximizes heat rate efficiency, and also minimizes the potential damage to the furnace from flame impingement, tube leaks, excessive soot, slagging, and many other potential operational problems.
To achieve balance and avoid these problems, many facilities use permanently mounted O2 probes at different locations inside the flue gas duct and average the readings inside the control system to optimize the total furnace fuel-to-air-ratio. Readings from the O2 probes also provide an indication of the stratification of flue gases inside the furnace.
“Many traditional O2 analyzers have had a fixed insertion depth, and engineers have had to guess at the best placement of the probes,” Simmers explained. “The new longer probes from Rosemount Analytical not only reach further into these large ducts, but they now have the ability to be adjusted after installation so that the entire width of the flue gas duct can be characterized.”
The X-STREAM line of combustion O2 probes offer long life in this difficult service, and are now designed to be repaired without removing the probe from the furnace duct. Additionally, they can provide indication of reducing conditions that may occur inside the furnace during plant upsets.
