A burner and a gas water-heating device, the burner comprising: a burner body (100), the burner body (100) having a gas intake chamber (10), a first combustion chamber (20) and a second combustion chamber (30) that communicate in sequence; and a flow divider (200), which is arranged between the gas intake chamber (10) and the first combustion chamber (20), the flow divider (200) being used to divide a gas flow of the gas intake chamber (10) and deliver same to the first combustion chamber (20) and the second combustion chamber (30) separately. In high-temperature air combustion completed by means of the flow divider, gas, or air, or a mixture of gas and air is properly distributed to the two-stage combustion chambers, which reduces the emission of pollutants and reduces the noise of the gas water-heating device. |
