PROBLEM TO BE SOLVED: To provide a compact water-cooled jacket for burner having a simple structure. SOLUTION: The space between the inner tubes 11, 21 and the outer tubes 12, 22 of double tube structure serves as a cooling water channel and a burner is inserted into the inner tubes 11, 21. Partition members 13 are provided at radially symmetric positions separated by 180 deg. in the circumferential direction in order to section the annular space between the inner tubes 11, 21 and the outer tubes 12, 22 into two in the circumferential direction. Cooling water flows into one sectioned cooling water channel S1 and flows out from the other sectioned cooling water channel S2. |
