Vitomax  RS waste heat boiler for steam generation

Waste heat boilers utilise the heat from flue gases generated during combustion processes or hot exhaust air from industrial processes to generate saturated steam. Due to economic and statutory considerations, waste heat boilers are frequently used in conjunction with gas turbines and combined heat and power units. Given increasing energy costs in particular, waste heat boilers can be a very good choice.

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 is avoided.

How waste heat boilers work

Viessmann waste heat boilers are designed according to the flame tube:smoke tube principle. Hot flue gas is routed through pipe bundles, where the heat is transferred to the water inside the boiler body.

To minimise radiation losses, the waste heat boiler is fitted with 100  millimetre thermal insulation and a metallic casing. As with all  Vitomax boilers, a base frame spreads the load evenly across a large floor area.

With or without auxiliary combustion

Waste heat boilers without auxiliary combustion equipment use only flue gas/exhaust air to generate saturated steam. Waste heat boilers with combustion equipment are conventional boilers with a burner and waste heat utilisation.

Waste heat boiler with additional combustion

Conventional Vitomax HS with additional waste heat flues

All fired  Vitomax RS are suitable for the combustion of up to 100  % hydrogen when complying with our general conditions for the use of H2.
