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 heat exchanger energy rate is calculated by multiplying the flue gas volume, specific heat, density, and temperature difference, then dividing by the conversion factor.
\begin{equation}\label{eq:cascade-high-to-low-hx-energy-rate} Q_{hx} = \frac{V_{flue} \cdot C_{p} \cdot \rho_{flue} \cdot \Delta T}{CF}\end{equation}
| \(Q_{hx}\) | Heat exchanger energy rate \([\unit{ \MMBtu\per\hour}]\) |
| \(V_{flue}\) | Flue gas volume \([\unit{ \scf\per\hour}]\) |
| \(C_{p}\) | Specific heat of flue gas \([\unit{ \btu\per\pound\degreeFahrenheit}]\) |
| \(\rho_{flue}\) | Flue gas density \([\unit{ \pound\per\scf}]\) |
| \(\Delta T\) | Temperature difference \([\unit{ \degreeFahrenheit}]\) |
| \(CF\) | Conversion factor (e.g., 1,000,000 for MMBtu) \([\unit{ \unitless}]\) |
