Title: white flames at below -0f
Post by: heat550 on February 20, 2015, 01:23:34 AM

 It was -10f and my 200ss does this if you keep loading 3-5 pieces of dry oak in every 3-4 hours .  water always above 150f
when you have door open fan on when loading and watch the flames change from yellow red blue to straight white .
when it does it you can feel mass of heat . anyone ever notice this . seen it few times only at -0f or colder .  cycle times are quit fast
also when its doing this .  I call it short loading the stove but wow does it heat up the house :)  Searched on net says its burning at 2900f with white flames .  Only noticed this sense burning some nice dry oak 20-25%

Im not saying that you are not seeing white flames but I will say you are not burning at 2900degrees thats a bit warm I think.

I get the same flames on my waste oil boiler when the air is just right, not 2900 degrees though, the cast iron firepot would never take that 8-12 hours a day.

I don't know if its 2900f but its dam hot . I read a bit more on it on the net about white flames . Its said its when the carbon partials
coming off a yellow to red flame ignites . I know it only did this white flame thing sense I burned nice dry oak . and yes I think 2900f would start milting stuff over time . But at below -10f and about 1 hour after loading stove . my cycle times fan on are fast like 10 -15 mins water temp of 150f to 170f  till its needs wood again 7-10 hours subzero. But I have good size load on the old 1996 model 200ss 5600 square feet . building temp range 45 f to 75f I feel lucky I got that video of it . Its the short loading 3-4 hours stove gets super hot .

The temperature range from Red to White: Wood

    Red
        Just visible: 525 °C (980 °F)
        Dull: 700 °C (1,300 °F)
        Cherry, dull: 800 °C (1,500 °F)
        Cherry, full: 900 °C (1,700 °F)
        Cherry, clear: 1,000 °C (1,800 °F)
    Orange
        Deep: 1,100 °C (2,000 °F)
        Clear: 1,200 °C (2,200 °F)
    White
        Whitish: 1,300 °C (2,400 °F)
        Bright: 1,400 °C (2,600 °F)
        Dazzling: 1,500 °C (2,700 °F)

I couldn't get info off a physics website but I  got this even 2600-2700f pretty dam hot .  :)
