AI Technical Summary
When the unit load changes and frequent start and stops in the existing water-cooled wall sealing device in the burner area, the sealing plate and the water-cooled wall pipe are inconsistent due to the expansion coefficient and expansion direction, resulting in greater stress on the corner weld, which is prone to cracks, which leads to leakage of the water-cooled wall, affecting the safe and stable operation of the unit.
Channel steel sealing device is adopted, including channel steel body, mounting plate, compression spring, adjustment frame and other components, which are connected to the water-cooled wall body through the channel steel body. The compression spring and clamping plate are used to ensure that the adjustment frame and channel steel body are installed closely, and the strength and sealing of the overall structure are enhanced.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of burner water-cooled wall sealing, in particular to a channel steel sealing device for preventing cracks from occurring in the water-cooled wall of a burner region. Background Art
[0002] Burner is a general term for devices that spray fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application fields. They are mostly made of corrosion-resistant and high-temperature resistant materials such as stainless steel or titanium. The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner, and under the action of the flame temperature and flame atmosphere, it undergoes processes such as drying, melting, evaporation, and dissociation to produce a large number of ground state atoms, as well as some excited state atoms, ions, and molecules. A well-designed burner should have high atomization efficiency, low noise, and stable flame performance to ensure high absorption sensitivity and measurement precision. Slit burners are often used to produce atomic vapor in atomic absorption spectrometry. Depending on the type of gas and combustion-supporting gas used, the length and width of the burner gap are different. Generally, the applicable gas and combustion-supporting gas are marked on the burner.
[0003] The water-cooled wall is the main heat-receiving part of the boiler. It consists of several rows of steel pipes distributed around the boiler furnace. It has flowing water or steam inside and receives heat from the flame of the boiler furnace from the outside. It mainly absorbs the radiation heat of the high-temperature combustion products in the furnace, and the working fluid moves upward in it and evaporates due to the heat.
[0004] The existing burner area sealing plate is directly welded to the water-cooled wall tube, which plays the role of bearing the weight of the burner and sealing. The corner weld is subjected to greater force. When the unit load changes and the unit is frequently started and stopped, the burner sealing plate and the water-cooled wall tube are inconsistent in expansion coefficient and expansion direction, resulting in greater force on the corner weld between the burner sealing plate and the water-cooled wall tube, which is prone to cracks. When the cracks further expand, they will tear the water-cooled wall tube, causing water-cooled wall leakage, seriously affecting the safe and stable operation of the unit. Therefore, the present invention proposes a channel steel sealing device for preventing cracks from occurring in the water-cooled wall of the burner area to solve the above problem.
