Flare

Introduction and Model¶

The flare burns excess sewage gas from the biogas storage, when the storage tank's full capacity is reached.

The flare is implemented as a black box model, as its internal workings are not considered critical and are too complex to model in detail. The biogas consumption of the flare is calculated with the maximum gas uptake power and the current utilization of the flare. The utilization rate \(k_{load}\) of the flare depends on the biogas surplus \(\dot V_{gas}\) of the biogas storage tank. The following cases are assumed:

• High gas surplus (\(\dot V_{gas} \ge \dot V_{gas,max}\)): Flare is fully utilized (\(k_{load} = 1\))

• Partial gas surplus (\(0 \lt \dot V_{gas} \lt \dot V_{gas,max}\)): Flare is partially utilized (\(0 \lt k_{load} \lt 1\))

• No gas surplus (\(\dot V_{gas} = 0\)): Flare is not utilized (\(k_{load} = 0\))
