Lambda probe
With some clients we noticed that they misinterpret the role of the probes, so here is a little explanation.
Its mission is to measure the residual oxygen in the burnt gases. If it is too much oxygen it means that the combustion chamber lacks of fuel, or if there is not enough oxygen there is excessive of fuel. Automation through a specific formula (which of course is our secret) calculates the required amount of fuel. It converts from a fixed value which we enter at start-up of the burner. This value may be corrected by yourself according to the type and quality of fuel.If you exaggerate the amount of fuel the lambda will try to fix it but it will probably fail. You will have to reduce the quantity and observe the response of lambda. If the lambda is always below the value "1" then the fuel quantity is too low. You will need to increase the amount of fuel and observe the response of lambda probe. Correctness of settings is displayed on the screen that shows the lambda value and should rotate around number "1".
Also important is parameter called "the lambda probe response" as it limits how much will automatics add or take away fuel which is set in the 2nd working level of the burner. Should not overdo with the amount of response since it will require much more time to find the perfect balance than usual and there is a possibility that occasionally will smoke from chimney. Normally, this value is between 20 and 45%.
If humidity of fuel is over 35% than the lambda probe cease to work and therefore you are required to minimize the influence of lambda to 0%!Since the lambda in this case indicates deficit of fuel it will therefore start adding and thus overwhelm the combustion chamber by a large amount of fuel, which due to the moisture has poor combustion. Sometimes it is also necessary to reduce the amount of fuel in the settings.
For lambda probe to work properly is occasionally necessary to clean it. Simply we unscrew it and blow it with air. Worse is the fuel, more often must be monitored. If fuel is dry (less than 25% of humidity) is enough if lambda is monitored every 3 months.
