PURPOSE:To enable saving of energy by a construction wherein a heat storage part filled with a heat storage material is provided in a burner head on the upstream side of a flame holder, while an exhaust heat collecting pipe equipped with an air supply and exhaust pipe and having the heat storage material incorporated is provided. CONSTITUTION:In side-A burner equipment, air for combustion is supplied from an air supply and exhaust pipe 5, preheated by a heat storage material 3 of an exhaust heat collecting pipe 6, preheated further by a heat storage part 4 in a burner head 2, preheated then by a heat transfer part 8 and mixed with gas for combustion from a gas pipe 7 in a flame holder 1 and combustion is started. After the combustion gas is used for heating in a furnace, it enters side-B burner equipment, preheats the heat transfer part 8, the heat storage part 4 of the burner head 2 and then the heat storage material 3 in the exhaust heat collecting pipe 6 and then it is exhausted from the air supply and exhaust pipe 5 via an exhaust valve 10. This combustion is conducted at an interval of 10 seconds, for instance, by changing over the side-A burner equipment and the side-B burner equipment alternately. According to this constitution, saving of energy is enabled. |
