The invention relates to the technical field of combustion heaters, aims to solve the problems that in the prior art, when a combustion heater operates, noise is high, gas temperature is high, the environment is polluted by direct emission, and pre-research or test plans of related equipment are easily exposed, and provides a silencing exhaust system for a combustion heater. The device specifically comprises a switching section, a thermal protection section, a spraying section, an axial expansion joint, a force bearing section, a height difference adjusting section, a diffusion section and a noise reduction tower which are sequentially connected. Wherein the switching section is used for being connected with a high-temperature fuel gas discharge outlet of a combustion heater; the spraying section is used for reducing the temperature of the fuel gas; the axial expansion joint is used for counteracting the axial thermal expansion stress of the pipeline; the diffusion section is used for reducing the flow rate o
