Narrative:

During initial taxi out; my first officer did not get a satisfactory test on the engine anti-ice with idle thrust as is a common occurrence on the fleet. He decided to wait until I advanced the throttles and had more pneumatic pressure to verify the valves would open; however he did not mention this to me. As we taxied out; we ran the checklist and I did not catch the fact that the engine anti-ice valves were still open. I don't have an explanation as to why I may have been temporarily distraction. ATC did not interfere with our checklist as we were about the only airplane on the ramp. Perhaps I turned my attention somewhere just as he called for the anti-ice valves on the checklist. I always make it a habit to touch the control that is called for on the checklist; but again; I have no explanation for how I missed the anti-ice valves in the wrong position. As a result; we taxied out and took off with the engine anti-ice valves in the on position with an OAT of 32 degrees C. Shortly after liftoff; we got a 'thermal anti-ice on above 10 degrees C' on the FMC scratch pad. At that point; I reached up and turned them off.

Narrative: DURING INITIAL TAXI OUT; MY FO DID NOT GET A SATISFACTORY TEST ON THE ENG ANTI-ICE WITH IDLE THRUST AS IS A COMMON OCCURRENCE ON THE FLEET. HE DECIDED TO WAIT UNTIL I ADVANCED THE THROTTLES AND HAD MORE PNEUMATIC PRESSURE TO VERIFY THE VALVES WOULD OPEN; HOWEVER HE DID NOT MENTION THIS TO ME. AS WE TAXIED OUT; WE RAN THE CHKLIST AND I DID NOT CATCH THE FACT THAT THE ENG ANTI-ICE VALVES WERE STILL OPEN. I DON'T HAVE AN EXPLANATION AS TO WHY I MAY HAVE BEEN TEMPORARILY DISTR. ATC DID NOT INTERFERE WITH OUR CHKLIST AS WE WERE ABOUT THE ONLY AIRPLANE ON THE RAMP. PERHAPS I TURNED MY ATTN SOMEWHERE JUST AS HE CALLED FOR THE ANTI-ICE VALVES ON THE CHKLIST. I ALWAYS MAKE IT A HABIT TO TOUCH THE CTL THAT IS CALLED FOR ON THE CHKLIST; BUT AGAIN; I HAVE NO EXPLANATION FOR HOW I MISSED THE ANTI-ICE VALVES IN THE WRONG POS. AS A RESULT; WE TAXIED OUT AND TOOK OFF WITH THE ENG ANTI-ICE VALVES IN THE ON POS WITH AN OAT OF 32 DEGS C. SHORTLY AFTER LIFTOFF; WE GOT A 'THERMAL ANTI-ICE ON ABOVE 10 DEGS C' ON THE FMC SCRATCH PAD. AT THAT POINT; I REACHED UP AND TURNED THEM OFF.
