RADIATION HEATING ENHANCED FURNACE

摘要

PROBLEM TO BE SOLVED: To utilize heat supply sufficiently by providing a radiation heat storage member for heating an object with radiation heat made of a melt growth ceramic composite material produced through unilateral solidification in the heating chamber within a furnace. SOLUTION: A granular radiation heat storage member 13 is dispersed into the heating chamber 2 within a furnace. The radiation heat storage member 13 is produced through conditioning of raw material powder and unilateral solidification process. A pit 15 for collecting the radiation heat storage member 13 is punched at a lower position of a hot air stagnant part 14 in the heating chamber 2 within the furnace. A part 17 for sucking the radiation heat storage member 13 collected in the pit 15 into the combustion air is provided in the path from a blower 16 to a burner port. A reheat/introduction mechanism returns the collected radiation heat storage member 13 back to a burner 8 and reheats the member 13 with a combustion flame 7 before introducing the member 13 into the heating chamber 2 within the furnace.
