Abstract:
1. A system for providing fuel having a desired calorie content to a combustion engine over a range of operating levels, comprising: a. a first fuel supply pipe containing a first fuel; b. a second fuel supply pipe containing a second fuel and connected to the first fuel supply pipe at a mixing point so that the first fuel mixes with the second fuel to create a mixed fuel having a first calorie content; c. a control valve in the second fuel supply pipe upstream of the mixing point; d. a process system downstream of the mixing point for processing the mixed fuel to create a processed mixed fuel having a second calorie content; e. a first control signal reflective of the first calorie content of the mixed fuel; f. a second control signal reflective of the second calorie content of the processed mixed fuel; g. a third control signal reflective of the operating level of the combustion engine; and h. a controller connected to the control valve for operating the control valve based on the first, second, and third control signals.
