Analysis and countermeasures for cracks in desuperheaters of boilers

The structure and features of the water-chamber type desuperheaters in Yunfu Power Plant are described, and the bursting positions in the desuperheaters indicated. It is concluded upon analysis that the cracks on the intake pipe of the desuperheaters are caused by concentrated stress due to large temperature difference, while those on the circular water chamber by the irrational structure and material. Countermeasures are adopted accordingly.
