1. A process heater combustion stabilization method, comprising
sensing current operating parameters for a process heater at a plurality of time intervals;
converting the current operating parameters into a time-varying signal;
comparing the time-varying signal against a multi-dimensional burner stability envelope defined by a stability window of the process heater, each boundary of the stability window indicating when a burner within the combustion system likely enters an unstable state; and
altering operation of at least one burner of the process heater in response to the time-varying signal breaching the boundary of the stability window.
