Abstract

The invention provides an arrangement structure for the lower header of the boiler cladding wall, which can eliminate the welding stress and expansion stress between the sealing steel plate and the pipe, solve the problem that the sealing steel plate tears the pipe wall due to the change of stress, and ensure Ensure the normal use of the boiler wall tube, and then ensure the normal use of the boiler. It includes the lower header of the front wall, the lower header of the side wall, the elbow of the side wall, and the sealing steel plate. The sealing steel plate is welded to the lower header of the front wall, the lower header of the side wall, and the elbow of the side wall. The isolation structure is characterized in that: the lower header of the front wall is located above the level of the lower header of the side wall, the bend of the side wall is one, and the horizontal distance of the bend of the side wall is reduced to the original Half of the sealed steel plate is specifically a carbon steel sealed steel plate.

Description

technical field [0001] The invention relates to the technical field of boiler structures, in particular to an arrangement structure for headers under boiler walls. Background technique [0002] At present, many boilers use the cladding wall structure in the structural design. The cladding wall is generally spliced ​​by pipes and flat steel. Its airtightness far exceeds the traditional brick-laying guard plate furnace wall structure, and the overall weight of the cladding wall is light. , the structure is easy to hang and fix, and it is convenient to solve the problem of expansion. In addition, the cladding wall can be used as a part of the overheated heating surface, so the cladding wall structure can be said to serve multiple purposes. However, during the long-term operation of the boiler, the bent pipe at the lower part of the cladding wall often bursts due to stress concentration, which brings great hidden dangers to the safe and stable operation of the boiler.
