MEASUR-Tools-Suite v1.0.11
The MEASUR Tools Suite is a collection of industrial efficiency calculations written in C++ and with bindings for compilation to WebAssembly.

The steam mass flow rate is calculated using the boiler rating, available heat fraction, blowdown percentage, and the enthalpy difference between steam and feedwater. Available heat accounts for losses in the combustion process.
\begin{equation}\label{eq:water-heating-flue-steam-mass-flow} \dot{m}_{steam} = \frac{R_{boiler} \cdot 10^{6} \cdot AH \cdot (1 - BD)}{h_{steam} - h_{fw}}\end{equation}
| \(\dot{m}_{steam}\) | Steam mass flow rate \([\unit{ \kilogram\per\hour}]\) |
| \(R_{boiler}\) | Boiler rating \([\unit{ \giga\joule\per\hour}]\) |
| \(AH\) | Available heat fraction \([\unit{ \unitless}]\) |
| \(BD\) | Blowdown percentage (fraction) \([\unit{ \unitless}]\) |
| \(h_{steam}\) | Steam specific enthalpy \([\unit{ \kilo\joule\per\kilogram}]\) |
| \(h_{fw}\) | Feedwater specific enthalpy \([\unit{ \kilo\joule\per\kilogram}]\) |
