Narrative:

We had a completely full flight including a jump seater. As a result; we had approximately 300 lbs of fuel to burn to accommodate the jump seater. After push back; we told ground control that we needed to run up the engines to burn the fuel and we were ready for taxi. Ground control cleared us to taxi to runway 33 via taxiway a; C; short of runway 1. After an airplane landed on runway 1; we were cleared to cross and taxi via taxiway C; K; J and hold short of runway 33. About half way down taxiway C; ground control asked us to hold short of runway 33 at taxiway C and we could do our run up there. After sitting there with the engines powered up (75% N2) for approximately 5 minutes; ground control cleared a general aviation airplane to taxi to runway 33 holding short of runway 33 at intersection J. I looked to the west at the general aviation ramp and did not see an airplane taxi from that direction. There is another general aviation ramp further east of taxiway J. Since it was clear from the west; I assumed it was coming from the east taxiway and left the engines powered up. About 3 minutes later; ground control asked me to reduce the power to idle until further advised. We sat short of the runway for approximately 7 minutes more as we waited for edct (expect departure clearance time) time. We were then cleared to takeoff; and tower told us to use minimal thrust when taking the runway as there was a disabled aircraft behind us. I do not know if the aircraft taxied into our jet blast or whether that was what caused the aircraft to become disabled.looking back on the situation; ground control should have been contacted to determine the location of where the aircraft was taxing from and asked if I needed to reduce thrust to accommodate their taxi path. I don't know if there was an event but there should not have been an aircraft behind us.
