Combustion efficiency is determined by Oxygen content and temperature of Fuel gases. An excess air (Oxygen) condition reduces the efficiency as it carries away the heat while a deficient air (Oxygen) produces an incomplete combustion with consequent higher costs and increased polluting emissions.
A high Flue gas temperature indicates low efficiency as it carries away more energy. Simultaneous measurement of Oxygen and Temperature is essential to effect an optimum Fuel / Air ratio for maximum efficiency. HNL Fuel efficiency monitor precisely performs this function. In addition it calculates and displays the efficiency instantly to afford the operator a continuous feedback to adjust the burner controls to achieve the right Fuel/ Air ratio.
Automatic Self Calibration : Field Calibration is automatic & begins with every start up with fresh air aspirated instead of Gas sample.
Automatic self check for efficiency calculation: With aspirated fresh air specific percentage efficiency of the selected Fuel is displayed as a check on its calculations.
Self Supervisory Diagnosis : Continuously checks the status of :
1) Battery Voltage
2) Sample Flow
3) Oxygen Sensor
B) Different Temp.
E) C02 (Calculated)
|0-25 % in Stack Gas|
B) Different Temp.
D) CO (for other, please contact HNL)
