Calculation and display of combustion efficiency
 Using the following formula, calculate the combustion efficiency E.
Combustion efficiency E [ ％ ] =100 – Fuel coefficient [k]
•
Standard oxygen concentration value [vol%]－Measured oxygen concentration value [vol%]
Note 1: Fuel coefficient [k] is according to the fuel used.
Refer to the table below.
Note 2: Temperature of flue gases should be measured separately.
Connect the electromotive force signal of the thermocouple type temperature detector (R-
type) to this unit.
Note 3: The standard oxygen concentration value is to be 20.8 [vol ％ ].
Note 4: When the internal calculation result of the combustion efficiency [E]
exceeds 0 [%] ≤ E ≤ 100 [%], % is displayed.
Setting the fuel coefficient [k] to 0.73.
