Description
Technical Field
[0001] This utility model relates to the technical field of boiler air preheater installation equipment, and in particular to an installation structure for heat storage elements in boiler air preheaters. Background Technology
[0002] Air preheaters are crucial components in industrial boiler systems, primarily used to recover heat generated during combustion. They transfer heat energy from flue gas to water or ash through heat exchange, thereby reducing energy waste and improving the boiler's heat recovery efficiency. In traditional industrial boilers, air preheaters achieve heat recovery through complex heat exchange structures, with heat storage elements being a key component. However, with increasingly stringent environmental regulations and ever-growing demands for energy efficiency, traditional installation structures are no longer sufficient for modern boiler systems.
[0003] In practice, the existing installation structure has a single installation mode, which requires disassembly of the entire equipment during manual maintenance. This increases the labor intensity, occupies a lot of equipment for auxiliary operation, increases maintenance costs and overall operating costs, and brings many inconveniences.
[0004] Therefore, this utility model provides an installation structure for the heat storage element of a boiler air preheater. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an installation structure for the heat storage element of a boiler air preheater.

A second positioning and installation module that works with the fixed box is installed on one side of the heat storage chamber.
[0008] The first installation module includes a second fixing plate. The bottom of the heat storage chamber is fixedly connected to an installation base plate. The bottom of the installation base plate is equipped with the second fixing plate. The top of the second fixing plate is threaded with third positioning bolts that are evenly distributed and extend to the inner wall of the bottom of the fixing box. The third positioning bolts are used for the one-time positioning and installation of the second fixing plate and the fixing box.
[0009] The second installation module includes a third fixing plate. The bottom of the second fixing plate is equipped with the third fixing plate. The top of the third fixing plate and one side of the heat storage chamber are fixedly connected to an installation side plate.
