This Youtuber has recently made a 300-500kW monster rocket burner where he 'breaks the temperature barrier' like the sound barrier in aviation as he calls it. He plays a trick with two oxygen nozzles inside the burner body making it so hot that it melts even the 2700 F rated refractory of his furnace, which is not a usual swirling around the crucible design as we all have, but a central burner inlet design. Looks spectacular, but with a decent welder and carbon arcs the same temperatures and even hotter (e.g. making calcium carbide CaC2 or melting lime CaO: 2600 C (not F)) can be achieved with much less energy and cost.
what a bunch of sick clickbait, I remember when NOBOX made real science , now he is in the same group as KOR, who cares if he can get a furnace stupid hot , Sadly, I have done that!!! what matters is being able to effectively use the furnace or forge for your intended application V/r HT1
