Abstract

The steam boiler has a circulation system for boiler water that has water pipes arranged to circulate boiler water and steam through the water pipes with a cooled device arranged to cool a selected, exposed part of the steam boiler. The cooled device has an outer tube and an inner tube arranged in the outer tube. The outer tube, at an upper end thereof, has an open connection to one of the water pipes in which water pipe a flow is established.
