The utility model discloses a heat-pipe type double-fire grate back-burning boiler. The structure of the water jacket of a boiler body is composed of a boiler shell, a boiler container and a vertical pipe. The transverse water pipe of the interior of the boiler container is connected with the water jacket of the boiler body. The interior of the boiler container are provided with an upper combustion chamber and a lower combustion chamber. The boiler container is provided with an upper fire door and a lower fire door corresponding to the boiler body. The upper combustion chamber is composed of a shed pipe which is connected with the water jacket of the boiler body, fire-resistant material which is arranged in the shed pipe and a fire grate which is composed of a group of gravity type heat pipes. The evaporation section of a gravity type boiler pipe is made into a fire grate, and the condensing section of the gravity type boiler pipe is arranged in the water jacket of the boiler body. The utility model solves the problems that the water cooling fire grate is scaled, and then the heat efficiency of the boiler is reduced, etc. The utility model is suitable for steam boilers, hot-water boilers and atmospheric hot water boilers.
