RE:Contract timeListen if the contract to replace all.plasma torches would take this much time Pascalli would have should have asked if this is to replace all your burners or just a few and if the answer was few then he probably would have not gone in right away Maybe he would have gone with company B or C Especially C who seemed more eager to replace their burners. So installing this 1 to 2 single torches amongst fossil burning burners with in a same plant would not yield the result expected The whole plant would have to be refurnished with torches to see the desired effect.
