Abstract

High-pressure heaters, as an important auxiliary machine to improve thermal economy, are an important part of a million-level secondary reheat unit. With the continuous deepening of the supply-side reform and the development of high-end power equipment for higher parameters, the serpentine tube heaters will become the mainstream of future development. The pipe bend wall thickness designed by GBT 151 is higher than that of foreign products, and there is a certain gap in economic and energy efficiency compared with foreign products. Through the finite element analysis, it is found that the serpentine tube could be designed according to the EN 12952-3 standard under the premise that the bending process meets the thickness of the inner and outer walls.
