HONEYCOMB HEAT RESERVOIR, HEAT STORAGE BURNER USING THE HEAT RESERVOIR, HEATING FURNACE, AND HEATING METHOD

摘要

A honeycomb heat reservoir (11) and a heat storage burner using the heat reservoir, the honeycomb heat reservoir comprising a plurality of honeycomb structural bodies having partition walls and through holes surrounded by the partition walls, wherein the opening ratio of the honeycomb structural body (1-1) positioned at a center part and/or the hydraulic diameter of the through hole of the honeycomb structural body (1-1) is smaller than the opening ratio of the honeycomb structural body (1-2) positioned at the outer peripheral parts other than the center part and/or the hydraulic diameter of the through hole of the honeycomb structural body (1-2), whereby a flow at each part of the heat reservoir can be kept constant, a heat exchange efficiency can be increased, and the life of the heat reservoir can be extended.
