Is it in a steel shell or not? I'll try to answer later when I'm back in work (at a refractories manufacturing company)
Edit: ok, I've had a quick look but it's hard to say without knowing more about your particular materials spec, though as a rough idea, our heat flow calculator thingy gives a heat loss figure in the region of 200 to 300 BTU/sq ft/hr
