internal firebox temp

[nymapleguy607]

This may seem like an odd question but what would you estimate the tempature is within your fire box when boiling at full bore with forced draft?
I ask because I would like to add a viewing window in my new door and am trying to spec the glass accordingly
Thanks
Jeff

not sure but I am guessing it is greater than 1300 degrees F because you can almost get the doors to glow and cast iron will glow red at about 1200 degrees F. If I remember right anyway I could be wrong!!! that high heat tempered glass is pretty expensive isn't it. I remember the glass I got for my wood stove I think like $150 or something. and that was 5 years ago.

My stack temp sometimes exceeds 1700 degrees 8' from the firebox, so I would guess mine is pushing as high as 2000 degrees sometimes.

I am thinking just a small 2x2 piece would be all I need. the biggest thing would be getting somthing to withstand the heat.

Jeff, would the window from a regular kitchen oven withstand the heat??

Wouldn't that glass get dirty real fast? I wonder how long you could see through it?

Your oven of a stove does not get as hot as a wood stove not even close. Check the temp dail on the oven and you will see the temps it get's to. You need to find glass made for extreme temps.

Woodstoves use a cermaic material Neoceram, you can buy it by the inch don't ask how I know). :(
It has a pretty high rating.

My forced air has as a site glass in the door,it's a 2 inch dia.pipe 2 inches long threaded on the outside and the glass is held on with a collar and it never gets hot.

If you use a threaded pipe as the sight port I think you can use a metal threaded ring or nut that is used in plumbing a sink, and a round piece of glass. The trick is to drill a hole in the pipe on the fire side of the glass and put the pipe where forced draft will enter the hole. This way you have cooler air on the fire side. Take a look at an older thunderbolt.

I can get the glass Neoceram from Mcmaster I think it had a rating around 1300 degrees.
