Given the significant energy-saving benefits of steam regenerators, why are they not used more in practice?

As the title says.
I heard it’s mainly due to thermal expansion and contraction, and the issue with using steel in heat accumulators hasn’t been properly resolved yet, right?
During design, the amount of heat used is just right, with no excess heat, so a heat accumulator is not necessary. If too much thermal design is used, the review won’t pass. Regenerative heat exchangers were not considered from the outset of the design, and moreover, they are only temporary; over a longer period of time, the losses associated with regenerative heat exchangers still represent a source of heat loss. If it’s not necessary, it’s generally not considered.
The answer above is correct; it better reflects the mindset of a business engineer
This market is not easy to expand; most of the products involved are continuous and balanced-type devices
The main purpose of a heat accumulator is to balance the load and the boiler’s output. In situations where the load fluctuates significantly, it allows the boiler to operate under more stable conditions, thereby improving efficiency and saving energy.
