Abstract

The results of investigation into the nature of damage to tube bends of the low-pressure evaporator of the P-90 heat recovery boiler installed at the Severozapadnaya cogeneration plant are presented. It has been found that damage was caused by cavitation wear due to action of steam-water flow.
