[0002] A boiler is an energy conversion device. Energy input to the boiler includes chemical energy from the fuel and electrical energy, and the boiler outputs a certain amount of thermal energy in the form of steam, high-temperature water, or an organic heat carrier. The boiler guard, a protective plate attached to the boiler's insulation, primarily protects the insulation layer from external damage. The presence of a boiler guard is crucial for maintaining proper operation and extending the boiler's service life. Existing boiler guards are mostly monolithic, fixed directly to the boiler's inner wall, making them inconvenient to install, remove, and maintain.

[0003] In view of this, the present utility model is proposed. Utility Model Content
