it will generate three simultanious sparks,,which will help fully quickly burn the ful,, it will not create an effect thrice of the single spark,,
multi tip sparks are usefull when the turbulance is according to it,, so that the fire wavefront reinforce each other rather then counteract each other,,
in this case i dont think it will give any positive results however i m also not too much sure but it will degrade performance to certain extent,,
