BOILER COMBUSTION ANALYSER (O2 & COe) 

Combustion Analyser CO/COe measurement is a direct measure of the completeness of combustion, unaffected by air. By monitoring the flue gas CO content at the boiler economiser area, the user can learn about the combustion condition. It serve as the closed loop feedback.

Optimise the combustion with the Stoichiometric Combustion.

Today’s stringent environmental regulations and increase the combustion efficiency of coal fired power station are constant hot issue to address.

One way to achieve this is by keeping a healthy combustion system within burners. The heat rate, efficiency, LOI, fuel consumption, fouling and slagging are all related to the localized concentraction of COe.

With the active CO/COe monitoring and measurements in the boiler, ensure combustion optimize at most times, which help to reduce emission, reduce fuel cost and maintenance, especially since monitoring O levels alone is not effective enough given the unreliability of Oprobes and the high risk of in-furnace air leakage.

CO/COe Measurement

CO/COe is a direct measure of the completeness of combustion, unaffected by air. By monitoring the flue gas CO content at the boiler economiser area, the user can learn about the combustion condition. It serve as the closed loop feedback.

For this, TECG provides the IN-SITU Oxygen (O2) and Carbon Monoxide Equivalent (COe) analyzer specifically designed for use on utility boilers and that features a cost-effective design for reducing operation costs.

The flue gas will be channelled through the gas sensor via the high temperature resistance Stainless steel probe, then return to the boiler.

Gas sensing element:

    • Oxygen (O2) measure by ZrO2 zirconium dioxide oxygen sensor
    • carbon monoxide(CO) equivalent COe (combustibles) by heated solid electrolyte gas sensor

Dust Resistance

The boiler flue gas is filled with the dust. The analyser equipped with the purge air and auto purge actuation to avoid blockage situation.

The analyser equips wit the compact design with die casting aluminium enclosure with field configure HMI – electronics, keyboard, up-front display of O2 and COe. Standard output analog 4 -20 mA and digital RS 485 communication to connect with DCS for optimisation.

 

ZOOM IN TO BOILER – ECONOMIZER GRID LEVEL O2 /COe MONITORING 

By having the grid level O2/COe installation,  we can map the combustion condition across the boiler.
Individual area air flow, burner condition can be monitored and maintained, in order to reach the complete combustion.
