The invention provides an inspection door structure of a waste heat boiler. The problem that according to an existing boiler inspection door structure, due to high-temperature deformation, boiler sealing performance cannot be ensured can be solved. The inspection door structure comprises an inspection door frame and a panel; the panel is mounted on the front side end face of the inspection door frame in a sealed manner; and the structure is characterized in that the inspection door frame is of a hollow frame type structure defined by four side walls, the interior of the inspection door frame is sequentially filled with a blocky ceramic fiber board and an aluminum silicate fiber layer from back to front, the rear side face of the blocky ceramic fiber board is limited through a peripheral baffle on the rear side of the inspection door frame, and the front side of the aluminum silicate fiber layer is compressed by the panel.
Description
technical field [0001] The invention relates to the field of waste heat boilers, in particular to an inspection door structure of waste heat boilers. Background technique [0002] At present, the inspection door of conventional boilers is mostly a structure with a panel on the door frame. The material used is generally cast iron or steel for ordinary boilers. Its thermal insulation and high temperature resistance are not enough to meet the waste heat of some imported flue gas with extremely high limit temperature. Therefore, ordinary inspection doors are easily deformed at high temperatures and cannot guarantee the tightness of the boiler, causing various safety hazards. Contents of the invention [0003] In view of the above problems, the present invention provides an inspection door structure for waste heat boilers, which can solve the problem that the existing boiler inspection door structure cannot guarantee the sealing performance of the boiler due to high temperature...
