A control system and method for controlling a fuel processing system operational to produce a gas for a downstream process from a fuel, wherein the fuel processing system uses a plurality of fuel processing elements, a fuel input and a waste gas input, each of the fuel processing elements having an individual output and the plurality of fuel processing elements having a collective output, and wherein the downstream process has a waste gas output and a dynamic gas load demand. The control system includes a device for receiving communication from the downstream process indicative of the dynamic load demand and a device for controlling the collective output level of the gas in response to the dynamic load demand. The device for controlling is operative to at least one of substantially equally distribute the dynamic load demand among the plurality of fuel processing elements such that the individual outputs from each of the fuel processing elements are substantially equal to each other for forming the collective output and most efficiently distribute the dynamic load among the plurality of fuel processing elements such that at least one of the individual outputs contributes to the collective output.

Control system and method for controlling a gas generating system

A system for generating a desired output gas from an input fuel for use in a downstream process is disclosed. The system includes a plurality of fuel processing units to generate the desired output gas, wherein each of the plurality of fuel processing units includes a reformer which uses waste gas output from the downstream process to facilitate the processing of the fuel. Each of the fuel processing units is operational over a range up to full capacity, wherein the plurality of fuel processing units are interconnected in an collective operating scheme to process the fuel. A control system is provided for controlling the plurality of fuel processing units in response to requirements of a dynamic load demand from the downstream operation. The control system is operative to adjust the operational level of each of the plurality of fuel processing units to produce individual responses from each of the fuel processing units. The individual responses are combined to produce a collective response for meeting the requirements of the dynamic load demand. A method for generating a desired output gas from an input fuel for use in a downstream process is also provided.
