Abstract: In A Power Plant, heating retrofitting for high-temperature reheating pipeline, low-temperature reheating pipeline and
IP cylinder exhaust steam pipeline of two sets of 1 000 MW ultra-supercritical unit were carried out, and the medium-pressure
and low-pressure steam supply was realized. This paper introduced the reformation such as heating retrofitting system plan, hydraulic
calculation, strength calculation, stress calculation, equipment &pipeline layout and I&C design, etc., which can be used
as a reference for similar type of units.

Key words: heating retrofitting; ultra super-critical; system design
