Bosch Industriekessel GmbH
The steam boiler type UL-S is a three-pass shell boiler and fulfils all the requirements in the medium to high output ranges.
The flame tube, internal water-flushed rear flue gas reversing chamber, first smoke tube and second smoke tube are all arranged for optimum flow within the cylindrical pressure vessel. In interplay with one another, the radiant and convection heating surfaces promote rapid water circulation, thereby accelerating the passage of steam bubbles to the steam chamber. The heat supplied by the fuel is converted into steam quickly and with no material stress due to an even transfer of heat. The large water chamber offers sufficient storage volume to be able to accommodate sudden peaks in demand.
