Associated causal chains
This component is part ofInstallation causal chains— from cause to effect (gas quality → engine → exhaust gas → heat → efficiency). The AI reads the entire chain, not just the individual value.
Link with the entire installation
A CHP unit is never alone: electricity, heat and gas are linked, and with PV and battery storage, it becomes a system. The AI calculates the entire installation.
Frequently asked questions
What is the influence of Lambda on NOx in the CHP?
A higher Lambda (lean operation, e.g., 1.5–1.7) reduces the formation of nitrogen oxides compared to the stoichiometric zone (λ 1.0), as the combustion temperature decreases.
Why is a stable Lambda important for the operation of the CHP?
A stable Lambda ensures a constant chemical environment, which increases the efficiency of exhaust gas post-treatment and prevents uncontrolled NOx peaks.
At what point does the risk of NOx increase with a drop in Lambda?
If the Lambda drops below the target range towards 1.0, the combustion temperature rises rapidly, exponentially promoting the formation of thermal NOx.
How does a Lambda that is too low influence engine speed?
A Lambda that is too low leads to a mixture that is too rich, which increases the risk of knocking and increases the mechanical load on the CHP.
Why is lean operation often chosen for the CHP?
Lean operation allows for a higher operating temperature for efficiency while reducing NOx formation thanks to a controlled excess air ratio.
How does the installation react to Lambda fluctuations?
Large fluctuations in the Lambda value lead to unstable exhaust values, posing challenges for exhaust gas post-treatment control algorithms (e.g., SCR or SNCR).
