Vitomax  HW high pressure hot water boilers from 0.35 to 20.0  MW for industry

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.

The picture shows the H2 ready 100 % logo, which means that the boiler can be operated with up to 100 % hydrogen.

Product features

The  Vitomax HW high pressure hot water boilers meet all new statutory requirements for particularly clean combustion. The efficiency of these boilers with heat exchanger is over 95.5  percent, even at 100  percent load.

Regardless of the fuel used, the  Vitomax HW delivers an output of up to 20.0 MW. It is specifically designed for the manufacturing industry as well as local and district heating networks where high flow temperatures and pressures are required.

Low stress, space saving design ensures good natural circulation and reliable heat transfer. No additional boiler pumps are required, making hydraulic connection significantly easier. The  Vitomax HW 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. Water cooling guarantees a constant temperature around the burner head – the otherwise usual reflection from a refractory lining (which causes thermal NOx to form) does not occur.

The burner entry point and the rear flue gas reversing chamber of the  Vitomax HW are water-cooled. This means the energy in the flue gases is used exclusively for hot water generation.

All  Vitomax HW high pressure hot water boilers are suitable for the combustion of up to 100  % hydrogen when complying with our general 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 HW.

Just like all other  Vitomax boilers, the  Vitomax HW is equipped with sufficient inspection and access ports for carrying out important checks inside the boiler. As a result,  Vitomax high pressure hot water 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.
