Combined Heat and Power Plants – Efficient Energy Generation and Clean Emissions

Catalysts specifically reduce critical pollutants such as VOCs, CO and formaldehyde. This ensures that emission limits are reliably complied with – even under varying operating conditions.

Yes, the performance of a catalytic converter can be impaired by ageing or impurities (e.g. sulphur, siloxanes). Regular monitoring and maintenance are therefore crucial for a permanently high separation efficiency.

Catalytic systems enable the oxidation of pollutants at significantly lower temperatures. This reduces energy consumption, lowers operating costs, and allows for a more compact system design.

Catalytic converters are usually installed in the exhaust tract downstream of the engine. Depending on the system, oxidation catalytic converters or combined solutions are used, which are specially adapted to the composition of biogas.

Biogas is not a fuel with a constant composition. Fluctuations in methane content or impurities can lead to incomplete combustion – and thus to increased VOC emissions. These must be treated in a targeted manner in order to comply with limit values.

In addition to CO₂ and water vapor, nitrogen oxides (NOₓ), carbon monoxide (CO) and unburned hydrocarbons – in particular VOCs and formaldehyde – are also produced during operation. The level of emissions depends heavily on the gas quality and combustion efficiency.
