- Abstract
- An evaluation was made of the effects of radiant heat transfer from hot stove and chimney pipes to unprotected and protected room walls and ceilings. Pipe surface temperatures were 350 deg. C (662 deg. F) for normal operation, and 400-450 deg. C (752-842 deg. F) to simulate overfire conditions. Unprotected ceilings at 457 mm (18 in.) clearance met code recommended temperature rise limits for normal operation, but protection was needed for overfire exposures. Some protected walls allowed for clearance reductions to 76 mm (3 in.) for all exposures, while others needed at least 304 mm (12 in.) for normal and 457 mm (18 in.) for overfire exposures. Recommendations for model building code specifications for wall and ceiling protection are provided.
