what is the temperature of the firebox in an average woodburning firebox?

Question

considering, aprox 24 lb of kiln dried wood per hour - temperature in farenheit.

Answer 1

That's about 170,000 BTU/hr. I try to keep my firebox below 800F for lifespan considerations. This load sounds like it would be pretty close to that. Of course (if this is for home heating via hot air direct from the box) removing the heat from box to house with a fan is a big help and increases efficiency.
