[0002] A waste heat boiler is a device that utilizes waste heat in industrial production. By recovering the high-temperature heat generated in the industrial production process, it converts it into steam or hot water to supply the energy requirements in the process. The principle of a waste heat boiler is to convert waste heat into utilizable energy, reduce energy consumption, and reduce emissions. It belongs to an energy-saving and environmental protection device. Waste heat boilers are widely used in industries such as steel, chemical, and pharmaceutical industries, and play an important role in industrial production.

[0003] However, during the installation and use of waste heat boilers, since most of the waste heat boiler bodies are placed on the ground in the workshop through the base components, the bottom of the waste heat boiler is unevenly stressed under the support of the steel structure base during long-term use, which causes the boiler body to deform and affects the use of the boiler body. There is also a way to hang the waste heat boiler body on the top of the workshop to prevent the boiler body from deforming. However, since the waste heat boiler body is not only large in volume but also heavy in weight, the existing roof requires a special reinforcement structure to be able to hang and place it, and the required conditions are relatively high.
