The invention discloses a combustor and a gas water heater. The combustor comprises a shell, a premixer, a preheating combustor and a gas injection pipe, wherein the shell forms an air inlet chamber and a combustion chamber which are communicated with each other; gas and air are introduced into the premixer and premixed, and mixed gas is provided for the combustion chamber; the preheating combustor ignites the mixed gas in the combustion chamber and raises the temperature in the combustion chamber to a preset temperature; and the gas injection pipe is provided with an injection opening formed in the side portion of the combustion chamber and used for injecting gas into the combustion chamber, so that a high-temperature air combustion reaction can be carried out in the combustion chamber. The combustor with the high-temperature air combustion function and the gas water heater are realized. 本发明公开一种燃烧器及燃气热水器，燃烧器包括壳体、预混合器、预热燃烧器及燃气喷射管，壳体形成连通的空气进气室和燃烧室；预混合器接入燃气和空气并进行预混合，并向燃烧室提供混合气体；预热燃烧器将燃烧室内的混合气体点燃，并将燃烧室内的温度加热至预设温
