CHECK OF THE GAS QUANTITY ON START-UP
The check of the gas quantity on start-up is performed by using the following formula:
Ts x Qs 100
≤
where = Safety interval in seconds
Ts
Qs = Energy released in the safety interval expressed in kW
The Qs value is obtained by :
where Q1 is the flow rate in litres released in 10 starts within the safety interval.
Ts1 is the sum of the actual safety interval in 10 starts.
Qn is the nominal power.
To obtain Q1 perform the following:
● Disconnect the control electrode (ionisation electrode) cable
● Take the reading from the gas meter before the test
● Have the burner start ten times. This will correspond to 10 safety blocks.
● Retake the reading from the gas meter and subtract the initial reading. This will be the value of Q1.
example:
Initial reading
Final reading
Total Q1
● By performing these operations we can obtain Ts1 by timing one start (safety blocks) and multiplying it by
the number of starts.
example:
Actual safety interval 1.95 sec
Ts1 = 1.95 sec x 10 = 19.5 sec
● Should a value over 100 result at the end of this check, regulate the opening speed of the main valve.
