Fuel Mixer

Integration Into a Scheme

Connect the fuel flows as shown in the following figure.

The following figure shows an example of how to integrate the component into a scheme.

How the Component Works

The component represents the blending (mixing) process. With the activated Fuel material model Considering composition, different fuel flows must not be connected without the Fuel Mixer component. Otherwise the model message 8523 appears.

Technical Input Data

In the Technical input data (see the following figure with the material model Fuel, Energy), the proportion of the admixing stream in relation to the amount of energy can be limited by specifying the Minimum share of admixture and the Maximum share of admixture.

The share in the unit kW/kW can be converted to volume ratios if the heating values are constant. For example, if you want to mix a natural gas and hydrogen stream and limit the admixing stream of hydrogen to 10 Vol.-%, you can convert this in the following way.

\( \begin{equation} \begin{aligned} x_E &= \dfrac{x_{V,\ H2} \cdot H_{i,\ V,\ H2}}{H_{i,\ V,\ total}} \\&= \dfrac{10\ Vol.\text{-}\% \cdot 10,783\ MJ/m^3}{33,373\ MJ/m^3} \\ &= 0,0323 \end{aligned}\end{equation}\\\)

When the Fuel material model Considering composition is activated, the Technical input data also contain information on the Thermal and chemical state, for which you can Input estimated values or Adopt values from the main input flow:
