Description

Technical Field

[0001] The utility model relates to the field of mounting brackets, in particular to a mounting bracket for furnace water-cooled wall tubes. Background Art

[0002] A boiler is a device that converts the chemical energy of fuel into thermal energy, and then transfers the thermal energy to water, ultimately generating steam. Boilers are widely used in many industries and daily life. Water-cooled wall tubes are an important heat transfer pipe material in boilers. They are usually used in the boiler water of high-temperature and high-pressure boilers to absorb heat, transfer heat and cool. Existing water-cooled wall tubes are usually directly fixed to the inside of the boiler by welding during use. When the boiler is heated to generate steam and vibrates, the welding points are easily vibrated and become loose and not firm, causing the water-cooled wall tubes to loosen and shake. Therefore, we propose a mounting bracket for boiler water-cooled wall tubes to solve the above-mentioned problems. Utility Model Content
