Problems solved by technology

In the actual production process of this structure, because the suspension beam needs to be inserted into the gap between the two rows of tube panels, the precision of the tube panel bending is relatively high. In addition, due to the limited welding space, welding must be carried out every time a row of tube panels is passed through. When the number of tube panels is large, assembly is more difficult, especially when the last few rows of tube panels are installed, welding deformation, assembly tolerances, manufacturing tolerances and other unfavorable factors are superimposed, and assembly is extremely difficult, resulting in a longer assembly period

Abstract

Provided is a suspension tube structure for a tube screen of a boiler heating surface. With a suspension tube to replace a suspension beam structure to not only play the role of a suspension beam butalso increase the area of heating surface, the suspension tube structure for the tube screen of the boiler heating surface provides improvement in two different directions, wherein one is to effectively increase the area of the heating surface and improve heat exchange rate with the overall structure and the number of tube screens not changed, and the other is to increase the heating area of the suspension tube and reduces the number of the tube screens passing through the suspension tube with the heat exchange rate of the heating surface not affected to greatly reduce the difficulty of assembly. The suspension tube structure for the tube screen of the boiler heating surface comprises multiple U-shaped tubes, two hanging tubes and multiple suspension units, wherein the multiple suspensionunits are arranged side by side, adjacent suspension units are connected through one U-shaped tube, and the two suspension units located on both ends are respectively connected with the two hanging tubes. The suspension tube structure for the tube screen of the boiler heating surface is applied to the technical field of boilers.

Description

technical field [0001] The invention relates to a suspension tube structure, in particular to a tube panel suspension tube structure on a heating surface of a boiler. The invention belongs to the technical field of boilers. Background technique [0002] The tube panel on the heating surface of the boiler uses the heat of the high-temperature flue gas to heat the working medium in the tube panel, thereby reducing the exhaust gas temperature and increasing the combined cycle rate of the boiler to achieve the purpose of energy saving and environmental protection. Therefore, the heat transfer rate of the tube panel on the heating surface of the boiler plays a vital role in the operation of the boiler. [0003] See the accompanying drawings in the manual Figure 7 to Figure 12 Most of the suspension structure of the existing tube panels on the heating surface of the boiler adopts the form of square steel penetrating the tube panel, and the tube panel is fixed by the cooperation o...
