Title:
STRESS RELAXATION MECHANISM IN HEAT-ACCUMULATION PART OF REGENERATIVE BURNER
Document Type and Number:
Japanese Patent JP3714540
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To solve the problem in conventional burners, in which a heat accumulation part formed in a supply and exhaust gas-flow path is constituted as a completely closed space, in which heat-accumulation bodies are packed tightly to cause jostle from expansion arising from waste-heat collection of the heat- accumulation bodies and flow of combustion air and exhaust gas, resulting in that an external force is generated between the heat-accumulation bodies and ventilable support-plates, and the external force produces stress in the inside and causes breakage or deformation in burner tiles, the ventilable support- plates, a fuel-supply pipe and wear of the heat-accumulation bodies.
SOLUTION: The heat-accumulation part 3 is provided by being supported by ventilable support plates 2a, 2b in the supply and exhaust gas-flow path 1 formed horizontally. Heat-accumulation bodies 7 are packed in the part 3. In the pate 2a on one side, the upper part is directed to the outside of the heat-accumulation part, forming an inclination 5, and a release space 6 is provided in the gas-flow path in correspondence with the upper part of the inclined supporting plate.
