The utility model discloses a low-noise boiler structure. Boiler comprising a boiler chamber, a smoke outlet is formed in the top end of the boiler chamber; a pressure control interface is mounted onone side of the smoke outlet; one side of the pressure control interface is provided with an air valve interface; a sound insulation cover is mounted on the other side of the boiler chamber; a combustor is mounted on the inner side of the sound insulation cover; a connecting plate is mounted above the sound insulation cover; second damping springs are mounted on the two sides of the boiler chambercorrespondingly. Supporting columns are mounted on the two sides of the second damping spring correspondingly. First damping springs are installed below the supporting columns, supporting plates areinstalled at the two ends of each first damping spring, a combustion chamber is installed in the boiler chamber, a return smoke pipe is installed above the combustion chamber, a heat insulation layeris installed on the inner wall of the boiler chamber, and a sound insulation plate is installed on the inner side of the heat insulation layer. Due to the fact that the damping springs and the sound insulation plates are arranged, noise generated when the boiler works is effectively reduced.
