Instrumentation used to perform

continuous Fuel / Air trim on coal

fired Power Boilers, and the benefits

of an Online Extractive CO/O2 Grid.

Continuous Combustion Management (CCM) is

measurement and control of parameters previously ignored

that are critical to efficiency and emissions reduction

Why Delta CO ?

DMCC – CO Monitor Is

Designed for Power Plants

Resistant to latent ash

•Probe purge purges the probe and flushes sample line

•Sintered filter at probe head

Multiple (3) stages of

moisture and water vapor separation

Continuously, automatically

zeroes the non-dispersive

infrared analyzer.

Probe Features

Patented “ Extractive Venturi “ Designed to keep

ash out, Sintered Hastelloy filtration makes it last.

PROBE - Venturi Design, and Slip Stream ( Inertia )

effect, reduces ash contact with sintered filter

Separate Sample and Purge Lines, ensures lines and

sintered filter are kept clean.

CCM Benefits

• Reduced emissions

• Improved Efficiency

• Reduced (SCR) Ammonia Consumption

• Reduced LOI

• Reduced pulverizer wear

• Reduced wear on Coal Yard equipment.

• Reduced boiler tube & non-pressure part erosion due to lower flue gas velocities. Less Fan required.

• Improved ESP performance due to lower flue gas velocities.

• Reduced potential for slagging and fouling events

• Improved Pressure part life due to improved temperature profile

• Reduced ash disposal costs

• Reduced boiler tube failures due to reducing atmospheres
