The application of expansion joints in the waste heat boiler industry

author:创欣机械 data:2024-05-05 09:48:29visits:276

    Expansion joints play a crucial role in the waste heat boiler industry. Firstly, the expansion joint is an important component of the boiler system, mainly used to absorb the thermal expansion inside the boiler and compensate for the thermal displacement of the flue gas pipeline. During the operation of the boiler, due to the heat generated by fuel combustion, the temperature inside the boiler will continue to rise, leading to thermal expansion of components such as the furnace and flue. At the same time, the flue gas pipeline will also experience thermal expansion and displacement due to the heating of high-temperature flue gas. In order to ensure the safe operation of the boiler system, expansion joints must be installed to absorb these thermal expansions and displacements.

    In addition, the expansion joint also has advantages such as reliable operation, good performance, and compact structure, which can freely expand and effectively compensate for axial deformation. For example, corrugated expansion joints are widely used in the connection between pipelines, pipelines and equipment, and equipment and equipment. They have the performance of satisfying axial expansion, lateral translation, or angular displacement compensation to compensate for relative displacement caused by temperature differences or geological reasons in pipeline systems, effectively absorbing vibration under equipment startup, shutdown, or normal operating conditions.

    In summary, the main purpose of expansion joints in the waste heat boiler industry is to ensure the safe operation of boiler systems, improve system stability and reliability, and effectively absorb and compensate for various displacements and deformations caused by temperature changes or mechanical vibrations.
