Description

Technical Field

[0001] This utility model relates to the field of boiler reheater technology, specifically to a boiler reheater that is easy to disassemble and assemble. Background Technology

[0002] As a crucial component of a boiler, the reheater primarily increases the steam's enthalpy to enhance its work capacity, thereby improving the power plant's thermal cycle efficiency. To maximize the heating surface area, reheaters typically employ multiple serpentine tubes, secured by multi-layered clamps. These clamps prevent relative movement between the reheater's serpentine tubes and the clamps due to external flue gas and internal steam impacts, which could lead to tube wear.

[0003] In existing technologies, the ash left after the combustion of raw materials will affect the heating effect of the device if it is not dealt with in time. The reheater pipe wall is relatively thin, so the worn reheater pipe may cause boiler reheater leakage, and it is not convenient to disassemble, replace and inspect the reheater. Therefore, we propose a method to facilitate the disassembly and assembly of boiler reheater. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a boiler reheater that is easy to disassemble and assemble, and whose ash left after the combustion of raw materials can be dealt with in a timely manner, making it easy to disassemble, replace and inspect the reheater, which can effectively solve the problems in the background art.
