Product features

High pressure steam for industrial use

The boiler provides a continuous supply of steam at an output of 0.5 to 31.5 t/h whilst its operating pressure extends from 6 to 25 bar.

The lateral arrangement of the flame tube results in a highly compact boiler design that meets all the requirements for efficient steam generation.

Designed for larger industrial concerns

Water-cooled with low NOx values

No concrete is used for the optional innovative burner entry point in Vitomax boilers. This means it is water-cooled, and wear and maintenance-free, eliminating the need for replacement during the service life of the boiler. The water cooling guarantees a constant temperature at the burner head –– the otherwise usual reflection from a refractory lining (which causes thermal NO_x to form) does not occur.

The burner entry point and the rear flue gas reversing chamber of the Vitomax HS are water-cooled. Therefore the energy in the flue gases is used exclusively for steam generation.

Use of hydrogen

Long boiler service life thanks to low shearing forces

The spacing between the individual smoke tubes, as well as from the smoke tubes to the boiler casing and to the flame tube, comply with statutory requirements. The shearing force on the end face floors caused by different linear expansion in the smoke tubes and the flame tube is therefore extremely low. This design guarantees a long service life for the Vitomax HS.

To make it particularly easy to service and maintain, just like all other Vitomax boilers, the Vitomax HS is equipped with sufficient inspection and access ports for carrying out important checks inside the boiler. As a result, Vitomax high pressure steam boilers achieve the longest possible inspection intervals. Easy to open boiler doors and a cleaning door at the end of the boiler also ensure that maintenance is simple and contribute to low running costs.
