Contact our sales expertsA corner tube boiler is a natural circulation water tube boiler. It differs from other water tube boilers in that it has the characteristics of a water-steam cycle. The pre-separation of heating steam and steam-water mixture occurs outside the drum in an unheated downcomer. This type of boiler is called a corner tube boiler.
