FUEL GAS WITH LOW HEATING VALUE AND BLENDING CONTROL

PROBLEM TO BE SOLVED: To control an improved blending of fuel gas. SOLUTION: A method includes blending a first fuel (84) with a second fuel (76) at a ratio to produce a third mixed fuel (66). The first fuel (84) has a first heating value, the second fuel (76) has a second heating value, and the thi...

Zusammenfassung:	PROBLEM TO BE SOLVED: To control an improved blending of fuel gas. SOLUTION: A method includes blending a first fuel (84) with a second fuel (76) at a ratio to produce a third mixed fuel (66). The first fuel (84) has a first heating value, the second fuel (76) has a second heating value, and the third mixed fuel (66) has a third heating value. In addition, the first heating value is different from the second heating value. The method also includes feedforward controlling the third heating value of the third mixed fuel (66) via prediction and correction of a fuel flow rate of the first and/or second fuels (84, 76) and adjusting the ratio of the first and second fuels (84, 76) based on at least partly a comparison between a measurement and a target for the third heating value.
