Abstract
There has been provided an improved process control optimizer for regulating at least one parameter of the process relative to optimum utilization of available energy. Temperature responsive open loop control means regulates the fuel flow and the optimizer is operatively responsive to the fuel flow for regulating air flow for combustion of fuels such that the fuel air mixture is minimized. The improvement includes a means for delivering a digital output code for governing the air mixture in accordance with the optimum characteristic of the process and digitally responsive means receive said codes for decreasing air at a selected first rate and increasing air at a relatively faster second rate, the rates corresponding to respective reductions and increases in fuel flow about a selected optimum operating point.
Claims12
An improved process control and optimizer for regulating at least one parameter for the process relative to optimal utilization of available energy wherein temperature responsive open loop control means regulates fuel flow and the optimizer is operatively responsive to the fuel flow for regulating air flow for combustion thereof such that the fuel air mixture is minimized in accordance with optimum operating characteristics for a selected temperature of the process wherein the improvement comprises:
- means for delivering digital output representative of the change of fuel flow for governing the air mixture in accordance with said optimum characteristic of the process, and means responsive to said output for decreasing air at a selected first relatively slow rate and increasing air at a relatively faster second rate, corresponding to respective reductions and increases in fuel flow about a selected optimum operating point.
