The safe boiling point temperature is calculated as 96.328% of the saturation temperature at the outlet water pressure. This safety margin prevents the outlet water from reaching the boiling point, which could cause operational issues in the heat exchanger. The saturation temperature is determined from steam tables based on the outlet water pressure.

\begin{equation}\label{eq:water-heating-steam-safe-boiling-point} T_{bp,safe} = 0.96328 \cdot T_{sat}(P_{w,out})\end{equation}

Symbols

\(T_{bp,safe}\)	Safe boiling point temperature \([\unit{ \kelvin}]\)
\(T_{sat}\)	Saturation temperature at outlet pressure \([\unit{ \kelvin}]\)
\(P_{w,out}\)	Outlet water pressure \([\unit{ \mega\pascal\abs}]\)
