Investigation of the heating characteristics in a reheating furnace with pulse combustion

摘要

This paper presents a theoretical and experimental analysis of a pulse combustion in reheating furnace. Measurements of the composition content on flue gases and heat balance tests were carried out for operating parameters in reheating furnace. Experimental results show an intensive and efficient heating process. An attempt was made to perform theoretical computation of composition content in the reheating furnace. Satisfactory agreement between calculations and experimental results was found in certain regions. Discrepancies might be caused by sample of the combustion products which were assumed to be uniform distribution out of the reheating furnace. The results show that the pulse combustion has comparatively large influence upon both combustion and heat efficiency in a reheating furnace.
