COMBUSTION HEATING FURNACE AND HEATING METHOD WITHOUT CAUSING OXIDATION UTILIZING SAID FURNACE

摘要

PURPOSE:To permit continuous heating without causing oxidation with low-grade fuel by segmenting and separating the space in a furnace to a combustion space for forming a flame and a heating space for heating an object to be heated by using a solid surface having many gas passages. CONSTITUTION:Fuel and air are supplied separately through inlet connecting pipe parts 1, 2 to a burner 3 and are mixed in a mixing pipe part 4. The inside of the furnace is partitioned to a combustion space 7 and a heating space 6 by means of a ceramic honeycomb 5 constituted of a solid surface having many gas passages. The gaseous mixture is burned in the space 7. The heat generated by the combustion in the space 7 heats the honeycomb 5 itself to a high temp. thereby accelerating the combustibility of the fuel. An object to be heated is placed in the space 6 and since the space 6 is segmented and separated from the space 7, the combustion condition in the space 7 does not fluctuate even if there is minor fluctuation in the temp. and stable continuous combustion with the low- grade fuel is made possible.
