[0002] A boiler is an energy conversion device. The energy input into the boiler includes forms such as chemical energy in fuel, electrical energy, and thermal energy of high-temperature flue gas. After being converted by the boiler, it outputs steam, high-temperature water, or organic heat carrier with a certain amount of heat energy. It is mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises. The main working principle is a thermal power device that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container, so that the water reaches the required temperature or steam at a certain pressure. When installing and erecting a boiler, it is usually necessary to set up a boiler steel frame in advance. At present, when assembling and fixing the boiler steel frame, the threaded connection method is generally used for assembly.
