What are dry steam and wet steam?

The transition from water to steam is not a uniform one, and does not take place in its entirety when industrial steam boilers operate. This why the steam that circulates through the boiler circuit is largely wet steam, or in other words, it still contains a small proportion of liquid water.

The larger the fraction of water in the vapour quality, the lower the calorific value that is transferred to the process or product that depends on it.

From the point of view of energy efficiency, operating an industrial steam boiler should provide the maximum dry or saturated steam, i.e. steam that is free of bubbles, drops in suspension and water in liquid form, and with the highest calorific value, with a vapour quality of 1.

ATTSU manufactures and installs saturated dry steam boilers for industrial sectors which need to guarantee steam of the highest quality for their processes.
