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 BHKW 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 main purpose of the oxidation catalyst in the BHKW?
It serves the catalytic conversion of pollutants such as CO and formaldehyde into harmless substances at operating temperatures between 380 and 450 °C.
How to recognize a deactivation of the catalyst from the measured value?
A Delta-T close to 0 °C above the catalyst signals that no exothermic reaction is occurring anymore and the catalyst is deactivated.
Why is the temperature difference (Delta-T) so important?
The exothermic reaction produces a typical difference of 10 to 30 °C; this serves as a direct indicator of catalytic activity.
From when must a catalyst be replaced due to H2S poisoning?
A significant drop in Delta-T with a constant inlet temperature indicates chemical poisoning by hydrogen sulfide.
What temperature is typically present before the catalyst?
In reference installations, temperatures before the catalyst are in the range of approximately 464.7 °C.
How does the operating temperature influence efficiency?
The catalyst requires a specific temperature window (380–450 °C) to optimally maintain catalytic activity.
