HEAT STORAGE-TYPE COMBUSTION DEVICE

摘要

A heat storage-type combustion device has: a burner (22) which is provided with a fuel gas supply pipe (21); and a heat storage chamber (24) in which a heat storage material (23) is housed. An air guide path (25) which guides combustion air to the heat storage chamber and an exhaust gas guide path (26) which guides combustion exhaust gas discharged through the heat storage chamber are connected to a single gas supply/discharge device (27). Three-way switching valves (28, 29) are respectively provided to the air guide path and the exhaust gas guide path. An exhaust gas discharge pipe (281) is connected to the three-way switching valve of the air guide path, and an air introduction pipe (291) is connected to the three-way switching valve of the exhaust gas guide path.
