Industrial Process Electrification Feasibility Framework - Complete Guide

Electrification feasibility begins with understanding the thermal physics of the incumbent process: how heat is transferred (conduction, convection, radiation), where losses occur (refractory, exhaust, radiation), and how tightly temperature must be controlled to meet product specs. This defines the minimum deliverable thermal power and allowable transient deviation.

Next, engineers translate thermal requirements into electrical domain constraints: required voltage, current, frequency, and duty cycle. Resistive heating demands stable DC or low-frequency AC but suffers from radiative losses above 1000°C; induction enables deeper, more localized heating but requires precise coil design and impedance matching — especially as material resistivity changes with temperature. Plasma systems introduce complex arc stability, electrode erosion, and NOx formation trade-offs that demand rigorous CFD-EM co-simulation.

At the system level, feasibility hinges on three interlocking boundaries: thermodynamic (can the electric source achieve required T and dT/dt?), electrical (can the grid and plant infrastructure support the load profile without violating IEEE 519 harmonic limits or protection coordination?), and economic (does the NPV of avoided fuel, carbon, and maintenance costs exceed capital, O&M, and grid service costs over 20 years — with sensitivity to electricity price volatility and policy risk?). Real-world deployment success depends on treating these not as sequential filters, but as co-optimized variables in a multi-objective optimization engine.
