Ο2 Probe

A Zirgonia Oxygen probe is placed at the chimney and receives continiously measurements of the residual oxygen concentration. The Oxygen percentage is been calculated according to the Nernst formula.

Control Unit

The Control Unit, consists of a touch screen that indicates the combustion results, emission measurements, inverter operation levels and fault alarms.

Control Unit

Control Unit operates along with the inverter of the primary air of the burnerIt controls the speed of inverter and has the possibility of automatic or manual operation.

Combustion Analysis

Contacts flue gas measurements and calculates combustion efficiency.By pressing F3 combustion analysis is printed at the printer connected with the control unit. Type 4ECO2-L keeps record of one year combustion data.

Energy Saving4ECO2 provides the ability to carry out continuous measurement and correction of combustion quality, regardless of fuel quality and other conditions It saves energy 2-5% without taking into consideration energy saving from VCD

Controlling excess air is the most important tool for managing the energy efficiency and atmospheric emissions of a fuel combustion

Payback investment calculationEfficiency CheckBase Case (as Found):

Excess O2, %: 5,00%

Stack Temp: 220,00 deg C

Ambient Air Temp: 15,00 deg C

Sensible Heat Loss= 9,0%

Combustion Efficiency= 91,0%

Have the plant operator set the boiler load to the average load and maintain steady conditions (I.e. Boiler Master in manual):

Payback investment calculationNew Case with 4ECO2:

Excess O2, %*: 2,00%

Stack Temp: 187,00 deg C

Ambient Air Temp: 15,00 deg C

*Standard Excess Ο2 per Fuel type ( >50% Load, at Burner)

Sensible Heat Loss= 6,1%

Combustion Efficiency= 93,9%

Have the plant operator adjust the air flow to the standard %O2 below. Maintain safe firing by using good boiler operating practice (I.e. monitor Combustibles / CO in stack and/or visual combustion checks).
