Подскажите, пожалуйста, какой из этих двух терминов является аналогом русского "щелочение" (котла)?
Описание по тексту:
Two steam generation cleaning method are shown: boilout and alkaline degreasing.
Boilout requires heat input to the steam generation system to raise boiler pressure
and temperature, with the boiler filled up with boilout solution.
Alkaline degreasing does not require heat input from burners or steam and provides
system cleaning by using a water solution with alkaline chemicals.
Boilout can be performed at the same time of dry-out in the commissioning phase or
during startup, when the furnace is being warmed up.
Alkaline degreasing can be performed in the commissioning phase when heat
sources are not available.

Заранее спасибо!

Одновременно со щелочением ведется сушка печи, при температуре на перевале 290°С не менее 12 часов.
