First Claim
1. A system, comprising:
- a gas turbine engine comprising a combustor; and
a fuel blending system, comprising;
a first fuel supply configured to supply a first fuel;
a second fuel supply configured to supply a second fuel;
a first fuel circuit configured to blend the first fuel and the second fuel to form a first fuel mixture;
a second fuel circuit configured to blend the first fuel and the second fuel to form a second fuel mixture; and
a controller configured to regulate blending of the first fuel mixture and blending of the second fuel mixture based on a measured composition of the first fuel.

Abstract
A system includes a gas turbine engine having a combustor, and a fuel blending system. The fuel blending system further includes a first fuel supply configured to supply a first fuel, a second fuel supply configured to supply a second fuel, a first fuel circuit, a second fuel circuit, and a controller. The first fuel circuit may be configured to blend the first fuel and the second fuel to form a first fuel mixture. The second fuel circuit may be configured to blend the first fuel and the second fuel to form a second fuel mixture. The controller may be configured to regulate blending of the first fuel mixture and the second fuel mixture based on a measured composition of the first fuel.
