I wonder if they could run on wood gas.

  Probably. The 1300C burn temperature ought to even make it quite clean. I would guess the main limiting factor will be that these machines cost tens of millions of dollars, and even with a small probability of the wood gas damaging the machine, the owner will say no to any experimentation. Having said that, the manufacturers do tend to like to add extra things to the spec sheets of their turbines, so might well support trials of such things. It's obviously gonna be needing extra infrastructure for heated feed pipes (to keep the wood gas from condensing) and high temperature valves, filters, and flow meters. You might be needing gas composition sensors and a feedback system to deal with the fact wood gas can be pretty variable in its composition. I would imagine you might also tap off some of the post-combustion hot gasses from before (or even after) the turbine to act as thermal input to your gasifier too. That wouldn't be strictly necessary, but should improve efficiency.
