Vitomax HS –– ideal for industrial use

The Vitomax HS steam boiler complies with category IV of the Pressure Equipment Directive 97/23/EC, with a permissible operating pressure of 6 to 30 bar. It is used in manufacturing industries such as food processing, fertiliser production, construction materials, paper, beverages, chemical and pharmaceutical industries, hospitals and refineries, where steam is used as a process, propulsive or reaction medium.

Hydrogen up to 100 percent

In chemical operations such as the manufacture of chlorine and other industrial processes, most of the hydrogen gas is not used and is released into the atmosphere. Vitomax boilers, which can run on 100 percent hydrogen with an appropriate burner, offer a cost effective and efficient solution. At the same time a large amount of climate-damaging CO₂ emissions is avoided.

Product features

Vitomax HS high pressure steam boilers meet all the statutory requirements for clean combustion. The efficiency of these boilers with economiser is over 95.5 percent, even at 100 percent load.

Irrespective of the fuel used, the Vitomax HS delivers an output of up to 31.5 tonnes of steam per hour. It is specifically designed for manufacturing industries, where steam is required continuously. Thanks to its large evaporator with integral steam drier, high steam quality with low residual moisture is a key feature. The Vitomax HS can be operated very flexibly with light or heavy fuel oil, bio-oil or even (bio) natural gas.

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.

All Vitomax HS high pressure steam boilers are suitable for the combustion of up to 100 % hydrogen, subject to compliance with our conditions for the use of H₂.

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.
