[0002] Economizer installation is an essential link in the construction process of thermal power plants. During the installation process, the economizer needs to be hoisted to the height of the boiler frame for welding. When welding, the economizer pipes must first be aligned, and after alignment, the economizer pipes must be aligned. The relative position of the two pipe ports that need to be welded is fixed, so that the welding operation can be carried out, and because of the high-altitude operation, the operator needs to be suspended in mid-air with a sling during the operation. The operation is very complicated and the work efficiency is extremely low. Bottleneck link in thermal power station construction
