Sintering Atmosphere
Sintering Atmosphere
(OP)
Can anyone advise on a problem observed looking inside a continuous mesh belt sintering furnace whilst at temperature, there appears to be a 'will o the wisp' haze at the front section just on and above the belt in the preheat zone just behind the flame curtain, this doesn't seem to moving around much considering the amount of gas flow which should be moving towards and passing over and through this area of the furnace, what exactly is this?





RE: Sintering Atmosphere
What is it hurting? Are you making density and properties?

Thanks for the reply, the observed situation was made when the furnace was empty and yet to be loaded. My concern is would this be detrimental to any components to be loaded into the furnace particularly because Of the unsure nature of what this "wispy haze' was. I am surprised that the gas flowing through the furnace and towards the front was not causing more turbulence of the haze? I just wondered what the haze could be and what may be causing this.
RE: Sintering Atmosphere
And second what oxygen and dew point are you running (and what gases)?
It could be some condensation from the flame curtain or debris on the belt.

RE: Sintering Atmosphere
The haze area is behind the flame curtain and constantly comes from a point which is on top of the belt surface in a central position only and never moves from that area even though the belt is moving through the furnace , the flame curtain is free of any moisture/condensation.

The op is running N2 apparently for purging or neutral atmosphere and H2.
Good point "what dew point?" Yes what dewpoint is the H2?
Could be H2O vaporizing - dew point?
