The invention relates to a tamping coke high-pressure high-temperature CDQ (coke dry quenching) waste heat boiler which utilizes high-temperature waste heat of circulation inert gas to generate high-pressure high-temperature steam in CDQ for a tamping coke oven. The waste heat boiler is composed of a hot-water heating section, a vaporization system and a superheating system, wherein the hot-water heating section is mainly composed of an auxiliary economizer, a low-temperature economizer, and a high-temperature economizer which are all in a spiral extended surface tube structures; the auxiliary economizer is arranged on the tail of the boiler, and the auxiliary economizer is connected with a thermal deaerator used for deoxidizing water which is not deoxidized after the effluent of the economizer; the thermal deaerator is respectively connected with the low-temperature economizer, and the high-temperature economizer and finally connected with a boiler barrel of a vaporization system through a connecting pipe sequentially; a natural cycle system is adopted for the waste heat boiler provided by the invention, and a forced circulation pump is not arranged, the potential fault point is reduced, and the power consumption is saved; and the superheating system comprises a low temperature superheater, an attemperator, and a high-temperature superheater, the high-temperature superheater is arranged in a downstream manner, the heat of the stable high-temperature superheater is transferred uniformly, thereby avoiding overtemperature booster of a superheater tube.
