[Stoves] Radiant Dome

[John Davies]

Greetings, 

Has anyone thought of replacing the metal mesh dome with one of ceramic ? or
better even a bed of ceramic stones. I will write in detail when I have more
time.

 

Regards,

John Davies.

Matthew,

You say:
Silicon Carbide seems like a reasonable mesh choice - chemically stable and
able to withstand high temperatures. It even has a higher emissivity than
stainless steels in the 0.7-10 micron wavelength range (red visible light -
mid-IR range), meaning that it will emit more EM radiation than a stainless
steel at the same temperature.

You say that silicon carbide has a higher emissivity and will emit more EM
radiation at the same temperature than stainless steel.
I think that this is the critical point: how to get more radiation at the
same temperature.

Thanks.
Paul
